How the pros are gearing up for the roughest, toughest race of the year

Paris-Roubaix is a tough event that puts huge demands on both riders and bikes so there’s lots of technology on display that’s not used in everyday road races, and here are some examples you can expect to see this weekend.

Many riders use wide tyres run at lower pressure than normal and double-wrapped handlebar tape to cope with the cobbles. Some add secondary brake levers to provide extra control when riding on the tops and put grip tape on bottle cages to prevent drink from flying out over the bumps.

Read our story: 7 pro tweaks to tame the Hell of the North.

The bike industry uses this race to demonstrate the durability of new products. Brands don’t develop a new bike, brake or wheel just for Paris-Roubaix, but if they do have something that makes a difference in a race as demanding as this then they have a marketing win. 

Of course, there are plenty of examples of riders winning Paris-Roubaix without any unusual equipment. Orica-GreenEdge’s Mathew Hayman famously won a couple of years ago on a Scott Foil aero road bike with no tweaks other than 28mm tyres rather than the typical 25s and a 53/44-tooth chainset instead of a 53/39. 

Many riders will opt for unusual setups, though. 

Shimano Ultegra RX rear derailleur

Why could it make a difference? All the bouncing and vibration over the cobbles can cause drivetrain issues. Most pros use a chain catcher to stop the chain dropping off the inner ring, but Tom Boonen’s still got stuck between the chainset and the frame in last year’s Tour of Flanders. Then, when he changed bikes, the same thing happened again and he was left stranded and any chance of an individual victory disappeared.shimano_ultegra_rx_-_1.jpg

The new Shimano Ultegra RX rear derailleur – available for both mechanical and Di2 (electronic) systems – features what’s called Shimano Shadow RD+ technology with a chain stabilising switch to control the drivetrain over rough surfaces like the Paris-Roubaix pavé.

pave-recon-16.jpg

This picture shows a chain bouncing around on the pavé with a standard (non-clutch) rear derailleur.

When you flick the switch it’s harder for the rear derailleur pivot to move, resulting in less chain bounce over uneven surfaces. The result is that the performance of the drivetrain is more stable; the chain is less likely to hit the chainstay, there’s less chance of it dropping off the chainring, and it stays on the cassette better. That’s what makes it an attractive option for the cobbles. The essential elements of the design have been tried and tested in mountain biking for a few years now.

Read our story on the launch of the Shimano Ultegra RX rear derailleur here. 

Who has it? Members of Trek-Segafredo were using the Ultegra RX rear derailleur at the Tour of Flanders last weekend so there’s a high chance that they will be again at Paris-Roubaix. A total of 14 (out of 18) World Tour teams use Shimano, so perhaps others will fit the new derailleur for Sunday’s race.

Can I get one too? The Shimano Ultegra RX rear derailleur will be available from mid-June 2018.

Disc brakes

Why could they make a difference? Paris-Roubaix is flat – there are no screaming descents – but if it rains the pavé becomes slippery, water puddles in the holes, and the dust quickly turns to mud. 

Disc brakes are able to offer a more consistent performance than rim brakes in rainy conditions because the braking surface is further from the wet and grimy road surface. 

Also, that braking surface is steel rather than the carbon fibre that’s used for most high-end wheels these days. Brands are continually trying to improve braking performance on carbon (see Bontrager’s new Aeolus XXX wheels, for example) but it’s generally not amazing.

One other potential benefit is that disc brakes provide more tyre clearance, although you see the pros squeezing 30mm tyres into dual pivot brake callipers with a nominal maximum tyre width of 28mm.

Of course, there are downsides to disc brakes too, wheel changes in the event of a puncture being the biggest concern. Most riders will be sticking with rim brakes but it looks like some think the positives outweigh the negatives. 

Who has them? Although no one (to our knowledge) rode with disc brakes at last weekend’s Tour of Flanders, they could make a re-appearance at Paris-Roubaix, where they were first seen in 2016 – used by Lampre-Merida and Direct Energie – before the UCI suspended their use in the peloton. 

Trek-Segafredo, for example, has said that the whole of its Paris-Roubaix team will be on disc brake bikes – the Domane SLR Disc, the Emonda SLR Disc or perhaps even the as yet unreleased Madone Disc (we wouldn’t bet on the latter making an appearance; that’s more likely to be launched in the summer). Team riders have been using disc brake bikes throught the spring. Trek-Segafredo includes 2015 Paris-Roubaix winner John Degenkolb, 2017 fourth place rider Jasper Stuyven and Mads Pedersen who finished second in this year’s Tour of Flanders, so there’s the chance of a disc brake bike being ridden to a big finish.

EF Education First-Drapac’s Taylor Phinney stuck a picture on Instagram recently of the disc braked Cannondale Synapse that he intends to ride in Paris-Roubaix. 

Several members of Team Sunweb will be riding Giant Defy Advanced SL Disc bikes.

Can I get them too? Oh yes! They’re everywhere! The Trek 2018 Domane SL 5 Disc, for example is £2,495 here.

Check out 12 of 2018’s hottest disc brake-equipped race bikes here. 

Suspension

Why could it make a difference? When you watch Paris-Roubaix on TV the pavé looks bumpy. When you ride it yourself it feels like you’re being repeatedly kicked in the arse while struggling to operate a jackhammer. The longer the sector goes on the more hurty and energy sapping it gets… But it’s fun! Anything that can help soften the bumps has to be welcome in terms of control, ability to lay the power down and reduction of fatigue.

Who has it? Some Trek-Segafredo riders are likely to be on the Trek Domane SLR Disc which has been around for a couple of years now. This bike comes with IsoSpeed technology front and rear which, although it’s nothing like mountain bike suspension, does help smooth the ride.

Go to our Trek Domane SLR 6 review for more details on IsoSpeed.

Specialized Roubaix Expert - Future Shock.jpg

Specialized supplies Bora-Hansgrohe and Quick-Step Floors with its S-Works Roubaix (among other bikes) which features a FutureShock system. This uses a spring housed inside the head tube to provide 20mm of vertical movement at the handlebar. Several pro riders, including world champion Peter Sagan, used this bike in last year’s Paris-Roubaix so don’t be surprised to see it make another appearance this year.

Read our review of the Specialized Roubaix Expert, another bike with the FutureShock system. 

Members of Team Sky have used Pinarellos with suspension over the past few years. Bradley Wiggins, for example, rode the Dogma K8-S – a bike that coupled flexible chainstays with a small elastomer damper at the top of the seatstays to provide a bit of extra cushioning – back in 2015.

Check out our story on the Pinarello Dogma K8-S from that time.

pinarello dogma k8-s 2017 3.jpg

Last year, a couple of Team Sky riders used the K8-S with an adjustable electronic rear damper. Pinarello partnered with a suspension company called HiRide to develop the uprated system. The eDSS 2.0 (Electronic Dogma Suspension System) uses six axis accelerometers and gyroscopes that are able to take feedback from the road and adjust the damper unit accordingly. Pinarello says it can adapt the suspension to suit all types of road surface and terrain in milliseconds. 

Check out our story on the Dogma K8-S for more details. 

The UCI approved the Pinarello Dogma K10S on 19 March 2018 (the disc version was approved towards the end of last year) so there’s a good chance that we’ll see that new bike raced at Paris-Roubaix. 

[Edit: And – hey presto! – Pinarello has just Tweeted a pic, below]

Can I get it too? You can certainly buy a Trek Domane with IsoSpeed and a Specialized Roubaix with FutureShock. You can buy the Specialized Roubaix here for £1,900.

The Pinarello Dogma K10S Disk frameset is available here for £6,699, although no rim brake Dogma K10S has yet been released.

And the stuff you won’t see…

SRAM 1x 

sram_force_1_rear_derailleur_1.jpg

sram_force_1_rear_derailleur_1.jpg

SRAM’s 1x (single chainring) system uses a rear derailleur that features a clutch to eliminate chain slack (it has been around since 2015 on the road, unlike the Shimano Ultegra RX rear derailleur that was announced earlier this week). This helps to keep the chain in place over bumpy surfaces.

sram_force_1x_chainset_1.jpg

sram_force_1x_chainset_1.jpg

SRAM’s X-Sync chainrings have tall, square teeth edges that engage the chain earlier, and the traditional sharp and narrow tooth profile helps manage a deflected chain.

Plus, Paris-Roubaix is flat so you could easily use a cassette that offers all the gears you need without having any big jumps between them.

Although the Aqua Blue Sport Pro Continental team competes on 3T Strada bikes equipped with SRAM 1x drivetrains, it won’t be racing Paris-Roubaix. 

Read our review of SRAM Force 1 here.

Tubeless tyres

Tubeless road tyres have been around for years now and they’re gradually growing in popularity, especially since Mavic introduced its Road UST wheel/tyre system last year. Advantages of tubeless tyres over standard clinchers include lower rolling resistance, reduced risk of flats and increased grip.

MavicSAS - 2.jpg

Check out our story: Mavic introduces Road UST tubeless system covering huge section of wheel range. 

While a tubeless system might make sense if you’re riding a sportive over the cobbles, the pros want the weight and performance advantages of tubulars, and if they do get a flat they'll just swap the wheel.

Tiesj Bendot won Strada Bianche on a non disc bike in piss poor weather conditions, what was Nick Terpstra, Vlaanderen winner - no discs ... when are you lot going to realise it's the grip of the tyres and the bike handling that is massively more important factors.

Discs are a joke in terms of how you and the manufacturers are pushing them, they simply are not needed for road racing even in very wet conditions, it certainly doesn't make it safer nor is there any performance advantage, quite the opposite.

Tubeless: SOME tubeless tyres are faster than SOME clinchers.

Have you got a disc brake bike or have you ridden one?  One of my bikes has 105 rim brakes with Swiss Stop pads on an aluminium rim and the other one has hydraulic SRAM disc brakes.  The rim brakes work fine.  Both systems slow the bike down, but for the same decrease in speed, the disc brakes are SO much easier in terms of the amount of pressure you need on the lever.  So, why wouldn't you go for the system that needs less strength to use?  Yes, they're heavier, but not by anything that I notice.  They are brilliant and, from my point of view, loads better.

and guess what Walt Van Aert the famous Cyclocross rider rode in a wet and muddy Strade Bianchi! (And Flanders) And Sagen, who’s pretty handy on a mountain bike, rode in the Tour of Flanders!

Looks like they pay the pros to ride discs in the more famous races (Roubaix, TDF) and the rest of the time they stick to what they need. 

Btw, discs are great on an MTB with 2” wide knobby tyres that can grip in mud.

Given how much goes into special suspension bikes for PR, surprised not to see the odd ShockStop stem in use. Fantastic & simple!

Ladders and BehinfTheBikeSheds are both bang on. The majority of riders are now choosing not to take the disc bike when given the choice (or in the case of the big hitters they’ll be refusing in case it hinders their chances of winning). The domestiques are generally the ones on the bikes, showing off the tech for the sponsors. If you’re a Pro rider you want the best bike for the job and it’s turning out to be the rim version. Trek started to the year stating that all riders would be on discs, but by Caltalunya they were down to one or two riders (I think it was one). Degenkolb is off them, GVA is off them, Sagan is off them, the list goes on.

 

Yes disc bike owners we hear you. You like the ‘modulation’ (or so you’ve convinced yourself after buying the next big thing) but the Pros are choosing not to ride them. They don’t give them any advantage and a wheel change is not fast enough compared to skewers.

So you readily admit you aren't that great at braking, fine, we can't all be able to learn how to brake properly and be bothered to set our brakes up properly, I've no beef with that.

But don't try the bullshit of saying the solution is a system that is flawed to high heaven and takes more effort to maintain the same speed than a caliper braked bike to make up for the fact you and others aren't able to use their brakes properly. This applies in racing/competition and offers no more safety benefit nor speed advantage for non competitive types either.

I've never not being able to modulate my braking, the only time I ever didn't have enough braking in 35 years of road riding was when I was using some old chrome steel rims in the wet in the early 80s, I was probably about 14/15 and I got a bit over-enthusiastic.

Maybe all the greats throughout cycling history have been doing it wrong without discs, how did they cope with narrow tyres too.

Wow.

Apparently in your incandescent disc brake fury you misunderstood both the tone and the content of my post.  Let's spell it out in big colourful letters so you get what I said.

I said rim brakes work fine.  I said they slow the bike down.  It sounds to me like they're working OK.  It sounds like I slow down when I apply the brakes.  Hooray.

I also said that it takes less effort to apply the brakes on a disc brake bike.  I didn't say that it was difficult to use rim brakes.  I didn't say anything about modulation.  I didn't say anything about maintenance.

So, in summary, rim brakes are fine, disc brakes are also fine but one takes slightly less force at the lever than the other.

The difference between riding disc or calipers could also be rider preference.

Let's face it, they'll hardly use their brakes in a flat classic, rim brakes will be sufficient.

But when it comes to using neutral service in the event of a puncture, I bet they've probably got more rim brake wheelsets onboard, plus these will have normal quick releases, less likely the thru axle front or rear your bike has.

For the favourites, it's a safer option to run normal brakes, for a domestique, not such a big deal.

Wooden rims were great, very light, but expensive to make.
