  • budget around £40 per tyre. Does anyone have any recommendations?

    Other than find some more budget?

    Seriously though, £40 is not a lot for a decent tub. I’m thinking that might cover a Tufo but it won’t get you anything (track legal) from Vittoria or Conti I wouldn’t have thought.

  • @M_V fair enough, and thanks for the reply. I had seen some road tubs that were around £40 and thought they might be ok (they'd be ok for HHV, but not for LVV I presume?).

    For example:
    https://www.wiggle.co.uk/vittoria-rubino­-pro-iv-g20-road-tyre-tubular

    Or:
    https://www.merlincycles.com/vittoria-ru­bino-pro-g-all-round-tubular-road-tyre-7­00c-140868.html

  • Yeah, not sure what the script is with tyres for Herne Hill but those definitely wouldn’t cut it at Lee Valley.

    For indoor you definitely want something where the manufacturer states ‘track’, ‘velodrome’ or ‘pista’ in the name/description. (Except Maxxis who say a dual compound tyre is for the track).

  • Great, thanks for the help! Will up the budget and see what I can find (there doesn't seem to be a whole lot of anything in stock right now).

  • Conti Sprinters are the cheap go to for training and track league at Newport.

  • Conti Sprinters are not listed as a track tyre by the manufacturer

    FTFY.

    They are widely used, without issue it seems, but by Conti's own defintion, they are not a track tyre.

  • Doesn't need to be defined by the manufacturer as a track tyre to be useable, just not dual compound and vinegared a few times before first usage. (They do say no coloured tread as well, but try telling that to the Dutch national squad... 😂) Are they starting to say that at LVVP? May be simpler to message it that way, I suppose...? Never used to is all.

    I've used Podium TT, Sprinter and Competition tubs and various incarnations of Vittoria Corsas/Chronos on LVVP with no issue whatsoever since they opened it up to the public in, what was it, 2015?

    I think things are tightening since this incident:

  • Would be quite the overreaction if it was, but stranger things have happened at sea... current regs were put in place after that crash (though I'm not sure if that was a direct consequence or just a coincidence).

    That was specifically about dual compound tyres, which the current regs have already addressed? Maybe a Lee Valley risk assessment done by someone who didn't actually know about the case, or track cycling in general?

    No mention of it in the current LVVP or Manchester guidance though. Interestingly, Manchester Velodrome says the OP's choice of Rubino pros is one of the recommended ones: http://www.nationalcyclingcentre.com/tra­ck/information/track-bike-specification/­

  • People use road and TT tubs all the time at Lee Valley (and all the other velodromes I have raced at).
    I used Veloflex road clinchers there for a madison training session there the other week no problem.

  • I dunno how much I can say really but yeah, that incident has made a lot of people that work in indoor velodromes in the UK somewhat concerned about tyres.

    The tyres were a pivotal part of that lawsuit (although maybe not the actual incident) and you’d have to be naive to think that tyres wouldn’t be heavily scrutinised in any future such cases.

    In the case of where I work, we are torn between producing a list of acceptable/unacceptable tyres (which would be out of date before anyone looked at it and would rile up those brands that don’t make the ‘acceptable’ list) and producing a more general definition of what a ‘track’ tyre should be.

  • I can understand it making people nervous, but I'm not sure they really understand why that case was successful. It was caused by the tyres, no doubt, but if the current guidance (no dual compound, vinegar/isopropyl alcohol etc) was adhered to, that poor guy would still be alive and no-one would have gotten sued.

    Case hinged on the publishing date of that current guidance. It was published after the accident and the velodrome's defence was "there was no guidance, so we couldn't have been negligent in its absence." Reason the case was successful was they managed to dig up an article on the BC site, published before the accident, which proved proved they already knew the tyres to be dangerous, with or without the guidance. Guessing that's why it took 7 years tbh!

    Do understand the need for caution (very scary, very dangerous) but in regards to that specific case, that window for litigation has been closed for years, so long as people enforce their own regs.

  • The links that were posted here represent where the lawyers found an avenue they could pursue, not the actual cause of the accident.

  • It is interesting to note that the trl article says some other dual compound tyres are grippier by the measurement method used.

    https://expertwitness.trl.co.uk/velodrom­e-case-study/

    It'd maybe be a useful follow up experiment to factor in more variables such as different tyre pressures, rider weight/mass, different speeds, track & arena temperature & humidity etc to get an even wider picture of the gripiness of the range of tested tyres across various conditions that may be encountered day to day.

  • Vittoria used to do a track tub with a light grey stickier section on one side

  • Just to add to the confusion,

    Maxxis make a triple compound 'velodrome tyre'.

  • Looking at how well mounted the tyres were on the test rig, I think the error bars on their results should maybe be slightly larger.

    It looks like they've basically chopped down existing tyres and wrapped it around a 16" diameter wooden disc.

    (BTW, I'm not disputing the overall conclusion. It would just be nice if the test could be done rigorously to get data that is definitely representative of real world conditions)
