Maybe – or maybe a youth
Maybe – or maybe a youth rider with a non-smart or otherwise highly inaccurate trainer/power measurement device. Meh.

‘m riding in the contraflow cycle lane, a bus is approaching (did I forget to say its more-or-less a single lane road, one way, but a main bus route?); the bus moves to go around a van parked unloading to the Chinese supermarket, not paying attention, then brakes as he sees me and another bloke riding a trike coming toward him.Now, I was riding in a marked lane and was actually at the pinch point caused by the parked van before the bus was, which from my point of view gives me priority so the bus ought to have waited until the road was clear of oncoming traffic (ie. me and trike guy!).
In my mind, if you guys were clearly visible and got to the pinch point first, then he should have let you go and in any case, certainly not just carry on. That said, if you had sight of the bus and anticipated the pinch point, then it might have been good to have let them through first (HC advice apart from anything else). I normally try to give extra allowance for PSVs and similar whether i’m in a car, on a bike or as a pedestrian and (HC aside) that is mainly that i’d prefer to slightly delay me, or a maybe a couple of others, rather than lots of other people – often in a time and resource constrained service. Greater good and all that. Blah blah. That’s just me though.

I’ve always thought hydrogen was the answer, as it is considerably cleaner than any current battery technology. If we want clean, we are backing the wrong horse. While there are now a few hydrogen vehicles on sale (most notably the new Hyundai), I doubt there will be the appetite to roll out hydrogen infractructure in addition to chargers.Alas hydrogen is a pretty dire thing to use for a fuel – current production techniques don’t help (vast majority of it is still produced using steam reformation) but even so you’re bleeding efficiency at every stage. Currently, electricity consumption per mile seems to be reckoned to be several times worse for hydrogen fuel cell vehicles over straight EV, and that’s without considering greenhouse-gas emissions. It’s a lovely idea, but it just doesn’t add up at the moment (maybe never).
A point that is yet to be mentioned here is that humanities addiction to the car will atleast drive a surge in battery technology – which is going to be necessary to move the grids to more renewable sources. In fact major advances are already happening – the man credited with inventing the Lithium Ion battery, may have just create (along with his assistant) the first solid state battery which is sodium based – so not a rare earth material, this battery:– Doesn’t suffer from the combustibility problem most convential batteries do
– Have a much better energy density – can be lighter and store more energy
– Much shorter charging times.
Hell yeah, and looks like they should have
* cheaper and easier manufacturing
* far greater active lifespan (lower cell degradation/charge cycle)
* much wider operating temperature range
He also absolutely has the best name going *
* ..and also part of the group that created the first ‘modern’ RAM modules. Still working, late nineties, boy’s a legend.
For any future reference, 11
For any future reference, 11-36 would have been fine with a RD-5800 GS without a hanger extender (Wolftooth, SunRace or loads on eBay for buttons) – they’ll actually run more than that but the shifting does start to go downhill apparently.

Summary – more stuff inline below if you want
- This is not about tubeless for Veloflex
- I said you made a judgement on the Veloflex SPS tyres without any experience, i’ll stand by that judgement until shown otherwise.
- I said ‘hate’, not you, that’s on me.
Yeah, at you. Bad afternoon and not in the mode for more bollocks. Yeah it will increase the rolling resistance to some degree, exactly what you don’t know but you already know they’re garbage. Not tried them, not apparently considered actually where the change *is*, not waiting for anyone to actually test them, nothing. FFS, another mouth attached to an opinion and no experience to base it on. Brilliant. Just what the world needs more of.As for the tyres – Veloflex are currently producing the non-SPS tyres and still selling them on the their site. Go look. Yeah they will “will gradually substitute the traditional version” in Veloflexs own words, but not now. They have a lot of track and TT people using the old open tubs, they’ll not disappear soon. When they do, if they finally get rid of all the open tubs, then we’ll have the SPS versions – the thing you hate, but have no idea about, but – given what Veloflex say about where and how the reinforcement is made – will make fuck all difference i’d bet given the details released so far and where the changes have been made. Do I know ? No, which is why i’ll reserve judgement until they’re put their paces on the road and in the lab. YMMV pretty fucking clearly.
Edit. Oh yeah, sorry forgot. They’re adding this to all the open tubs, because they’re worried about shit rims damaging the tyres. Not a tubeless thing.
you’ve got a real potty mouth roid rage going on there buddy bud bud, you might want to lay off for a while and go for a bike ride, it’ll calm your nerves.
Yeah, like I said, bad day – patience with some things at a low point.
. How many miles do you have riding tubeless tyres on standard clinchers with tubes in them, what widths (for me 25s and 32s) As you’re giving it the daddy big bollocks I expect you’ll have thousands of miles of experience of the two types of set up with similar tyres right. A best guesstimate is fine, plus name the tyres and even tubes because that’s actually quite important to keep constants when comparing and exchanging/sharing information.I have zero miles riding tubeless tyres on standard clinchers with tubes in them. Why on earth would I do that ? I do have a reasonably decent experience of tubeless tyres being used as intended, e.g. on the road, a few thousand km on 23mm Hutchinson Fusion 3s, quite a lot of thousand km on Specialized S-Works Turbo 2Bliss 28mm (going through a second set now) and about a 1000km or so on some new 25mm Mavic Yksion Pro UST (aka Hutchison Fusion 5 Storm 11).
2. Are tubeless tyres heavier/more re-enforced at the sidewalls than non tubeless tyres, yes or no?In general, yup.
3. Does a tubeless tyres’ re-enforced sidewalls give a more complient ride with tubes compared to the equivalent non tubeless tyre with a tube, yes or no?Nope.
ou understand the role that sidewalls play in tyres and how that effects matters directly on the road right?
Yes, I do, and the effect of inner tubes (butyl, latex or plastic) on compliance, Crr and ride. Ditto roughly where on the tyre the majority of the hysteresis losses occur. I also know what Veloflex say is the reason for the reinforcement and would have a guess (and that’s all it is) at where it might be. Based on those last two, i’d further hazard a guess at what sort of effect it might have on ride and Crr (hint: they probably don’t overlap much) but i’ll wait until they’re actually tested before actually making a judgement. We are talking about the Veloflex SPS system specifically remember.4. Could the added weight to re-enforce the tyre be added in a more useful/constructive manner, say to add to the tread thickness, which would give better longevity/puncture protection, yes or no?Yes, it could be added elsewhere. No, it would probably not be more useful/constructive if the wall or wall + sealant no longer performs its function. We are talking about the Veloflex SPS system though, in which the reinforcement is for a specific reason and so moving that reinforcement would therefore be counter-productive.
5. Hate is such a strong word, did I use the word hate or was it in fact you, yes or no, answer truthfully?No, true, projection on my part based on my interpretation of your previous posts. Mea culpa.
I really don’t think the internet is ready for you yet, making up stuff that people have said when they haven’t, a narrow minded singular view with no real world experience/no experience of what someone else has in fact but prepared to use foul language to tell someone they are completely wrong yet can’t produce any facts/evidence regarding that … oh hang on, the internet is perfect for you.
I was pissed off, as I said, and not ready for more bollocks, and apart from attriubuting ‘hate’ i haven’t made anything up by the look of it.Look what I said about the Veloflex tyres, look at what they are trying to do and where the reinforcement is likely to be made, and maybe consider how you know they’re “garbage”.
Ride what you like but tubeless specific tyres with tubes are garbage compared to like for like non tubeless tyres, the difference is noticeable to this user, the ride is harsher, slower and the tyres are for the most part more expensive too.Of course they are, never said otherwise, but why the hell would you run tubeless tyres with tubes ? If you want a discussion about tubeless/tubeless-ready and regular clinchers, then i’m more than happy to – I use both and have favourites from both camps, no axe to grind for either – but i’m not wasting time discussing how using something wrong makes them perform more poorly.
Yeah, at you. Bad afternoon

OP. Yeah you can just remove
OP. Yeah you can just remove the tyres and flog them – they turn up regularly on eBay – then put regular clinchers on.
Oh do give it a rest… at
Oh do give it a rest… at least until you’ve actually tried them. Seems like Veloflex are still producing the regular open tubulars without the SPS reinforcement anyway, but I understand that’s not the point.
About 0m. Otherwise you just constantly change the distance because ‘it’s only a few m more’.BUT it “is immediately before a 50MPH limit stretch of road, so motorists starting to increase speed above the 30 MPH by a few miles an hour, does not justify the grumpy face on the sign or a criminal offence or deploying our PC Revenue Generators in force as real crimes are escalating out of control.” Money making scheme !The hill to which they refer is about a half mile before the change in speed limit.
How far before a speed limit change should the authorities just say, “Yeah, fine, whatever…”?
Yeah, while you should just wait in this case I think it’s all about context. The ‘hill’ bit they’re talking about is a dip about 100m before the speed monitor, about 8-10% according to the Garmin last time I went up, itself about 40m from the limit sign and leading onto a straight section of dual lane road with a 50mph limit with bugger all side-roads- apart form a lane about 300m on the right, that i’ve seen maybe 2 people enter or leave in a decade or so. If you’re at or below the speed limit heading in that stretch you’re probably actively breaking to remain so, even after the side-road.Just before the monitor is a garden centre, which often means that traffic is at a stand-still waiting for people to turn right. Since they’ve had the speed monitor there i’ve seen a whole bunch of triggers – can’t say i’ve seen much if anything outside 33-35mph at the time i’ve been there (earlyish morning) – so while that might add to the stats, i’m not convinced it’s a particular safety issue in the most part during that period – could be a nightmare at other times obviously.. or not. Problem with Deenyview Road joining ? Not sure what that is, suspect it’s pulling out of Leigh Court garden centre.. be interested to hear more. To be clear, i’m absolutely not excusing people speeding up to ‘reach that limit !’ – that’s just wrong – but i’m curious as to why and where this testing is done given the many other issues with that road.
You do get some idiots on that road, but IME generally not there in that direction. The opposite direction is another story – going from 50-30 through that bit seems a tricky prospect for many.. The problems with that road appear much further down (North) towards the motorway with advisory markings, but no mandatory limit, to slow down past some houses and a pub – there’s been a number of incidents including cyclist fatalities there – and where there is a 2+ lane where there’s a regular bunch of idiots solo, speeding or both when i’ve been there in the car or on the bike. Recent fataility there too. The proposed reduction in speed limits should hopefully help there.
Lots of things to improve around there, and definitely put enforced speed cameras there, but headlines seem to be more about clicks than safety though, IMO anyway.

Also SRAM have somehow made it acceptable to charge more for 1x groupsets, it might be sexy and new but as you point out, there’s less to it!Wait a while, I bet you’ll start to see 2x GRX cheaper than 1x GRX…
Maybe, maybe not… currently the price difference between GRX 600 2x and 1x in the places with stock seems to be about 80 Euro, e.g. https://www.bike-components.de
As others have pointed out though, the difference between the 105 and GRX 600 is due to discount, 105 R7020 is about £799 full asking in the UK – it’s a non-question.
Depends on what Mavic you
Depends on what Mavic rims you have, but how about the Mavic Yksion Pro UST series or Hutchinson Fusion 5 11-Storm (same thing basically) ? Excellent reviews (and rolling resistance if that’s your thing) and may be designed to fit the rim you have.
I think I’ll stick to the cassette/derailleur mod…You guys reckon I could either use a Roadlink with existing medium cage derailleur OR replace the derailleur with the new GRX one?
I’d be tempted to try the existing rear mech with the cassette before trying a RoadLink or getting a new one – feedback from various places online seems to indicate it could well work with either winding the B-tension screw in or reversing it; when I went to an 11-34T from an 11-32T (fully supported) I didn’t need to even need to adjust it on a Shimano 6800 medium cage so I wouldn’t be surprised if it went at least a couple of teeth more with minimal furtling..
