“Structural integrity be damned!” Bike shop mechanics perplexed by shocking valve-finding wheel bodge – and suggest a “couple pieces of thick tape to hide the shame”; Demi Vollering’s double power nap + more on the live blog

As far as Wednesdays go, this is a pretty good one – plenty of sunshine still hanging around, a classics-style stage at the Tour de France, and Ryan Mallon keeping up to speed with all the latest cycling news and views on the live blog. You lucky people…

“Structural integrity be damned!” Bike shop mechanics perplexed by shocking valve-finding wheel bodge – and suggest a “couple pieces of thick tape to hide the shame”, as cyclists say “that’s one way to balance a wheel”

There must be something in the summer air that makes it especially conducive to crimes against bikes.

Yesterday on the live blog we featured the absolute monstrosity that is Brett’s drop-less DIY handlebar look

The "no-regrets" handlebar set-up (Brett Reynolds on Facebook)

… Which may be fine for the occasional hill climb (I’m still not convinced it’s necessary even for the British championships, if I’m honest), but has no place on an everyday bike. Sorry, Brett. It’s a no from me.

> "I should have done it sooner": Cyclist turns heads with "no regrets" handlebar set-up, cutting off drops because "it just feels perfect"

And last week, our eyes were exposed to the horrors of what the kind, benevolent people over at Trench Tales described as the “toothless wonder” jockey wheel:

Arrrghhh.

Today, we’re back at Trench Tales, that Instagram gold mine for mechanical misfortune that always makes you feel slightly better about your own neglected machine, to inspect one of the most bonkers bodges I’ve seen in a long, long while:

Now, that’s grim. Talking about taking ‘Your Bike Hates You’ to a whole new level.

I can picture the scene now: ‘I put the tube in, but the valve’s not poking through the wee hole for some reason’… ‘Hold on, I’ll get the toolbox – reckon a saw or some pliers would do the trick?’

After what must have been a good few minutes of head shaking, it seems the good people at Trench Tales still aren’t entirely sure what went on to that poor wheel.

“They knew the lil’ valve stem was under there somewhere, structural integrity be damned!!” they wrote on Instagram, after helpfully installing a longer replacement valve stem, to prevent further wheel hacking occurrences in the future.

“Sometimes, in the trenches, you gotta dig deep but I can’t even tell what they used to hack out that bodge! Perhaps a couple pieces of thick tape over that replacement long valve stem, to hide the shame?”

Might take more than a few pieces of tape to atone for those sins, mind you… But, hey, at least it amused a few people in the comments.

> "Every. Last. Drop...": Bike shop mechanics stunned by cyclist's "toothless wonder" jockey wheels that should have been binned months ago

“Never underestimate the power of meth and a set of pliers,” said one investigative Instagram user. I think he could be on to something there, you know.

“Handheld Dremel using a grinding wheel, with the wheel itself not held securely,” another user suggested.

“That’s one way to balance a wheel,” noted John.

“Seen that… more than once. You can imagine the pride in the artist after finishing that piece!” added Sargento, while another commenter tactfully described the technique as “marginal gains”. Who knows, maybe the hill climb crowd will pick up on it in time for the autumn season?

While Just Keep Spinning concluded: “At least you fixed the problem with the longer valve stem. Another happy customer.”

I’m sure they’re delighted with themselves anyway…

Live blog question of the day
Live blog bodged rim comment

Good point.

Adding to the speculation, road.cc reader hawkinspeter said: “That rim must be well over-engineered to still be working after that level of fettling. Looks to me like it’s a cheapish deep section rim for a fixie – looks cool, but heavier than it needs to be.

“I certainly wouldn't trust that as my understanding of wheels is that the strength comes from the rim acting as a compressive component (or whatever the correct term is), so cutting out a wedge like that is going to drastically reduce the strength.”

“I suspect the rim isn’t that weaker because most of the strength in a BSO rim like that will be coming from the rim channel, not the aero side wall,” added Secret Squirrel.

Though stonojrn countered: “I’d resist the temptation to ride that down a steep hill though.”

Me too, me too…

Tashkent City team, 2024 Tour de France Femmes (A.S.O./Thomas Maheux)
Tashkent City team down to just one rider with four Tour de France stage remaining, as DNFs rack up on treacherous day in the Ardennes

The Tashkent City team – the Uzbekistan-based Continental team controversially invited to this year’s Tour de France Femmes, while teams like the recently collapsed Lifeplus Wahoo were denied a wildcard spot – are down to just one rider left, with four stages of this year’s race remaining.

22-year-old national champion Yanina Kuskova is the last woman standing for the squad, who lost four of their seven riders on the very first stage on Monday, after Nafosat Kozieva failed to start today’s stage from Valkenburg to Liège, while Margarita Misyurina pulled out during the wet and constantly hilly ride.

Kuskova, meanwhile, is coping extremely well on her debut Tour de France, considering the circumstances and her lack of experience, finishing 62nd alongside Lorena Wiebes today on the hardest stage of the race so far, and sitting 73rd overall.

And her Tashkent teammates weren’t the only riders to fall victim to the difficult course and treacherous conditions this afternoon.

Misyurina was among six riders to DNF before Liège, including recent Olympic omnium silver medallist Daria Pikulik (who finishes sixth on stage one), Maggie Coles-Lyster, Elyne Roussel, Debora Silvestri, and Martina Alzini, while three other riders, Elisse Chabbey, Clara Emond, and Christina Schweinberger didn’t start this morning.

And the hill only started today…

Is cutting your drops off with a saw the perfect bike fit solution? One road.cc reader doesn’t think so…

The debate around Brett’s ‘cut your bars off’ advice for cyclists seeking the most comfortable bike position on the live blog yesterday shows no signs of slowing down.

Today, road.cc reader Kevin – another cyclist who found he had no need for the drops due to a persistent neck problem – got in touch to tell us he had also sawed his drops off in the past (I know, can’t believe two non-hill climbers have resorted to such measures).

> "I should have done it sooner": Cyclist turns heads with "no regrets" handlebar set-up, cutting off drops because "it just feels perfect"

However, Kevin reckons that the bike mutilation approach didn’t solve his problems – and that it was the decision to repurpose some tri bars which did the trick, without the need to rip a good handlebar apart.

Tri bar set-up to alleviate neck pain (Kevin McDermott)

“The guy thinks he has reinvented the wheel and his solution is not the best,” Kevin tells us about Brett’s DIY bar destruction.

“I am a cyclist and coming into the sport late at 30 (now 64) I always struggled on the drops due to a depressed vertebrae in my neck from playing rugby. Did what your guy did initially and chopped off the drops. It worked but was not the best solution.

“Luckily I am mates with a guy called Sean who runs Ken Foster cycling shop in Manchester. I discussed the issue with him and he came up with the solution – using H bars or tri flat bars. And this was 25 years ago.

Tri bar set-up to alleviate neck pain (Kevin McDermott)

“The levers are situated in such a position that you are always on the hoods. I have three bikes and they all have the same setup thanks to Sean. Yes, slightly old school with exposed cables on the bars. But it works. Out of the saddle climbing is a joy, no problem with shifting, either Shimano or Campag as I have both. With electronic shifting the cable issue would be tidied up.

“Just thought I would let you know that he needs to have a look at other solutions that have been around for decades.”

You tell ‘em Kevin.

And if you can’t get enough of all this drops discussion, Dan is currently working on a tech feature on that very subject – so keep your eyes peeled for that one.

Meanwhile, over at the Tour of Poland…

Away from the Tour de France/Benelux, and to more sunnier climes, as the ridiculously strong Thibau Nys proved two out of three ain’t bad at the Tour of Poland, the young Belgian taking his second uphill sprint of the race so far by overhauling Diego Ulissi at the end of a relentlessly tough mountain stage.

Wilco Kelderman and Ireland’s Archie Ryan finished third and fourth respectively on the steep, technical final climb, while Jonas Vingegaard comfortably held on to the race lead after testing his legs on a climb earlier in the day.

But if there’s one thing that this year’s edition of Tour of Poland has proved, it’s that on an uphill finish, it’s hard to beat Nys.

“I didn’t feel my legs at all”: Puck Pieterse hangs on for first professional road victory in epic sprint duel with yellow jersey Demi Vollering after scintillating and sodden classics-style stage at Tour de France, as Vollering and Kasia Niewiadoma land

Puck Pieterse may be used to winning on her cyclocross and mountain bike by now, but the 22-year-old multidisciplinary star is still a relative newbie on the road.

In fact, before this year’s Tour de France started on Monday, the Dutch star had only raced 10 times as a professional road rider.

Mind you, on eight of those occasions, she finished in the top 10, including at some of the sport’s biggest classics.

So, it’s no surprise that she’s taken to racing at the sport’s biggest event like a duck to a wet Belgian day, as Pieterse attacked alongside seasoned stalwarts Demi Vollering and Kasia Niewiadoma, before holding off Vollering at the line, to take her first pro road victory at the end of a sodden stage in Liège – and one that blew the GC race apart.

(A.S.O./Charly Lopez)

On a brilliantly designed spring classics mash-up course, the yellow jersey contenders initially engaged in a phony war through the Ardennes, as the rain poured on La Redoute and the Côte des Forges and first Chloe Dygert, then potential GC hopeful Cecilie Uttrup Ludwig fell foul of the conditions, crashing on the sketchy looking descents that make up Liège-Bastogne-Liège’s finale every April.

But on the final climb of the day, the Roche aux Faucons, the group exploded, as yellow jersey Vollering drove the pace. Niewiadoma, a perennial contender at the Tour, then launched, forging a group clear containing Vollering, Pieterse, and the young Dutch star’s Fenix-Deceuninck teammate Pauliena Rooijakkers.

(A.S.O./Charly Lopez)

After Pieterse added another few mountain points to the collection she’d inadvertently started earlier in the day while working for Yara Kastelijn, the impetus in the group slowly stalled as Vollering – for whatever reason – refused to co-operate.

However, buoyed by the promise of bonus seconds ASO had plonked on a drag not long after the Roche aux Faucons, and just as the chasers came into view, Vollering kicked again. That was that for Rooijakkers, but the remaining trio ploughed on, building a 30-second lead over a group containing GC rivals Évita Muzic and Juliette Labous (other pre-race contenders such as Mavi García and Riejanne Markus were even further backed) as they descending into Liège’s urban sprawl.

Niewiadoma, like she’s done on so many occasions in past classics, was the first to move, attacking with 800m to go.

But the Polish rider’s move only served to set up Pieterse who – unaware of where the finish was, she later revealed – kicked hard with 200m remaining. The imperious Vollering’s late burst, however, drew her level with her young compatriot, as the two crossed the line side-by-side after a scintillating sprint that looked, for a moment at least, as if it had succumbed to the yellow jersey’s unflinching inevitability.

An agonising wait later, however, and Pieterse’s breakthrough win on the road – just over a week after a puncture robbed her of a medal at the Olympic mountain biking – was confirmed.

29 seconds later, another revelation of 2024, Mauritius’ Kim Le Court led the next group home, after working hard on the front to limit her losses for most of the final kilometres. Despite Le Court’s effort, the writing already looks on the wall for anyone who missed out on the sodden Belgian hills this afternoon.

But while Vollering and Niewiadoma can be happy with their GC efforts, the day belonged to Pieterse.

“It’s quite unbelievable actually. The last few days I’ve had super good legs, and today I didn’t feel my legs at all. And to take the sprint here against Demi, it’s a dream come true,” the delighted 22-year-old said at the finish.

“I knew they were riding for the GC, and I’m just here to win a stage while I’m fresh, so I could play poker a bit in the final. I knew Kasia would attack, and Demi would have to follow, so I just tried to keep a poker face and take it in the sprint. I think I went quite early, but I’ve never been here so I didn’t know where the finish line was!

“We had to wait what felt like ages for the result, but I’m so happy to take the win. I live for this, I worked so much for the Olympic Games, and if you have good legs there, you have good legs here.”

Puck Pieterse has arrived.

Children “traumatised” after teenagers kick boy and steal his bike at BMX track

Children riding their bikes at a BMX track in Yeadon, Leeds, were left traumatised after a bikejacking attack in which two teenagers abused, pushed, and kicked a young cyclist off his bike, before stealing it and running away.

I hear a train comin’ on round: Level crossing halts peloton as riders prepare to hit Ardennes climbs

A rare sighting in pro cycling this year (but one that’s etched into the history of the sport), as the Tour de France Femmes peloton was forced to stop at a level crossing to allow a train to pass, just as the pace was ratcheting up ahead of the extremely hilly final 40km in the Ardennes:

For those of you new to the sport, once the level crossing lifted, breakaway rider Sara Martin of Movistar was allowed to head back up the road, reinstating the gap between the Movistar rider and the bunch that existed as she was brought to a halt. But with the action about to explode in the final 50km, I imagine her days are numbered anyway…

There’s Strava Art, then there’s world record-breaking Strava Art: American touring cyclist completes 4,708km, two-month drawing of her dog through the Netherlands, France, Belgium, Switzerland, the Czech Republic, Austria, and Germany

Move over you snowman doodlers and self-portrait enthusiasts – there’s a new Strava Art sheriff in town (and when I say town, I mean seven different countries and over almost 3,000 miles).

That’s because American touring cyclist Kristen Bellmer spent the entirety of May and June riding her bike around northern and western Europe, in order to draw a tribute to her dog Slinky, who died in November 2022, through the fitting medium of GPS.

Guinness record-breaking Strava Art (Kristen Bellmer)

By the time she finished her ride on 4 July, back in Amsterdam where it all began on 1 May, Kristy had cycled through the Netherlands, France, Belgium, Switzerland, the Czech Republic, Austria, and Germany – battling rain almost every day to boot during what she described as a very wet “summer” – and covered a whopping 4,707.67km (2,925 miles).

That mammoth ride saw her smash the Guinness world record for the largest GPS drawing by bicycle, previously held by two UK-based cyclists, Georgie Cottle and David Charles, who sketched out a 2,200km-long ‘Refugees Welcome’ GPS sign across the south of England in 2021.

“Guess I am officially amazing after all!” Kristy wrote on her blog, which documented her tough, wet, dog-shaped ride through Europe this summer. “Too bad I don’t actually have a wall to put my certificate on…”

Fair play Kristy, what a ride. Makes me feel like I should get my own dog a better Christmas present this year…

Mathieu van der Poel set to miss Vuelta a España ahead of rainbow jersey defence in Zurich

Mathieu van der Poel is eschewing the grand tour preparation that helped him win his first world road race title in Glasgow last year, as his Alpecin-Deceuninck team revealed that the Dutch star won’t be lining up in Lisbon this Saturday for the start of the Vuelta a España, ahead of his defence of his rainbow bands in Zurich at the end of September.

Instead, Van der Poel – who raced the Tour de France before soloing to victory on the rainy streets of Glasgow last August – will likely take on a series of one-day races as he builds up his form this year’s very hilly worlds, after taking some time off the bike following the Paris Olympics, where he finished 12th in the road race after missing the winning moves that led to Remco Evenepoel’s win.

The Tour de France does the classics: Stage four set for epic Amstel Gold/Liège-Bastogne-Liège mash-up

What’s going on? We’re in the middle of August and the sun’s out (for now), but today’s stage of the Tour de France Femmes is giving off such strong late April vibes that it’s got me reaching for my light jacket:

Tour de France Femmes 2024 stage four

In what I think is one of the great route designs of recent years, stage four is a brilliant spring classics mash-up, and one that could lead to some thrilling, GC-defining racing.

Starting in Valkenburg, the home of Amstel Gold, the early kilometres feature some of Amstel’s defining climbs, with an ascent of the Cauberg and two goes up the Bemelerberg, before the Tour heads south across the border into Belgium and Liège-Bastogne-Liège country.

The concluding 40km are a direct copy of Liège’s finale, and will see the riders tackle the Mont-Theux, the legendary La Redoute, the Forges, and the Roche aux Faucons, before a 13km drop down into Liège itself. It’s going to be epic.

Watch out for Olympic TT champion Grace Brown, who won Liège earlier this year (above), and will be looking for redemption after a puncture robbed her of a chance of victory aboard her golden bike during yesterday’s time trial.

All eyes, however, will be on yellow jersey Demi Vollering, a previous winner of both Amstel Gold and Liège, who could well put the GC to bed this afternoon, long before we reach France, let alone the Alps.

Demi Vollering wins stage three of the 2024 Tour de France Femmes in Rotterdam (A.S.O./Charly Lopez)
Demi Vollering’s guide to winning stages and wearing the yellow jersey at the Tour de France: Take two power naps a day

Finally, some pro cycling training advice I can fully get behind.

It turns out that Demi Vollering’s surprise time trial win at the Tour de France Femmes on home soil in Rotterdam yesterday (we say surprise, but it is Vollering after all), and earlier than expected reacquaintance with the yellow jersey, was the result of two perfectly timed day-time snoozes.

No, I’m not joking. Faced with the first split stage at the Tour de France since 1991, Vollering chose to wind down after the morning’s short 68km stage for the sprinters by taking a quick power nap at the hotel – which was rudely interrupted by her alarmed teammates – before finding time for some extra shuteye on the team bus before her time trial.

Demi Vollering wins stage three of the 2024 Tour de France Femmes in Rotterdam (A.S.O./Thomas Maheux)

(A.S.O./Thomas Maheux)

“I did two times a power nap, after the first stage,” Vollering said during the post-TT press conference yesterday evening.

“When we came back to the hotel I lay down on the bed and I fell asleep. Also, because I left my phone on the bus and didn’t have anything else to do, I fell asleep for 20 minutes, it was very nice.

“Then my teammates were knocking on my door and I stood up too quick and was like, ‘What?!’ They were like, ‘You were sleeping?'

“And then in the bus here after the recon I wanted to do some meditation and fell asleep again. I think I was bit too relaxed in the AM, I thought to myself it’s not going to go so good because I’m too relaxed and it’s such a short time trial, so you need to be very awake.

“But maybe power naps are very good for me.”

Demi Vollering wins stage three of the 2024 Tour de France Femmes in Rotterdam (A.S.O./Charly Lopez)

 (A.S.O./Charly Lopez)

I don’t think there can be much arguing with that, after home hero Vollering stunned Chloe Dygert in the afternoon time trial, beating the American by five seconds over the pan-flat 6.3km course through the streets of Rotterdam to win the stage and take the yellow jersey, in front of a jubilant Dutch crowd.

“I didn’t see this coming,” the 27-year-old admitted after the stage. “I really had no idea that I could do this today, so I’m surprised, actually.”

Reflecting on winning a stage of the Tour de France in her home nation, an emotional Vollering continued: “First of all, I’ve realised how special all this is for women’s sports in general, but to have so many loved ones at the side of the road. I’m a pretty sensitive person. I go with the moment and I’m really feeling. I do everything based on feeling.

“This year, I say, ‘Emotion is my power’. I always put all my emotions into the sport. I train with my feelings, I race with my feelings, so I think that this is my power. I’ve tried to put it away because a lot of people don’t like to see it, because you should show that you are strong in sports, but I think that sport is emotion for me.

(A.S.O./Charly Lopez)

“You work so hard toward goals and have so many people around you who support you and dedicate so much to you. I think that sports is emotion, so why not show it. For me, it comes out. A lot of people feel it, but you may not see it properly. But, for me, you just see it.”

Emotion and power naps – that’s what it takes to win the Tour de France. And write the live blog too, apparently.

I was looking at the description of the Vuelta route yesterday: one flat stage, five medium mountain stages, eight mountain stages, two individual time-trial stages and five hilly stages (2 with high-altitude finales) - so to do better than last year he'd have to take the three hilly stages that don't have high-altitude finishes and the flat stage, big ask!

Ref the drop-less handlebars, I have seen much more radical alternatives for hill climbing bikes. Ive seen a bike with flat handlebars and etap blips for the gears no shifters I think the rider just kept to transmitter electronics bit in their back pocket or somethng, but it wasnt on the shifter. the brakes were kids cable pull with enough to get 2 maybe 3 fingers on it. Its amazing how you can shed weight of a road bike.

You're absolutely right. The brake levers are Specialized Top Mount (usually used as secondary levers inline with the brifter cables), they weigh 80g for the pair. The SW-R600 is 79g and this shifter/lever combo was less than £100 - compared to say Dura Ace brifters weighing ~250g and much more expensive. Bike is currently 5.99kg and I reckon if I replaced the Mavic Ksyrium SL25 (1580g) with some cheap no-name carbon wheels from a popular far-eastern retail site and then put something lighter than butyl tubes in, it could be touching 5.5kg.

All academic, I won't be breaking any records, I'm 55, 85kg, dodgy knees, it's just fun for the love of bikes.

I'd resist the temptation to ride that down a steep hill though.

I'd have thought it puts force, essentially a bending force as the wheel rotates and compensates for the gap in the aero cover, to the rim channel in a direction it's not designed to cope with and be at risk of metal fatigue.

Probably thought that anyone doing that to a wheel needs to be removed from the gene pool asap.
