Which Tyres?

  • It should, the new Corsa 28mm in 18mm internal fit exactly 28mm wide, and the other good news is that the width of the thread on the 25mm is reasonably wide enough to compensate for the extra wide rims (if the thread width is narrower, the sidewall is gonna get cut up easily on extra wide rims).

    I also spoken to a Vittoria spokesperson today about it, and they were saying the new Corsa is better designed for wider rims.

  • Thanks; Kojak 35s ordered.

    Will report back.

  • Can confirm that 28's on a 28mm wide enve 3.4 rim fits under a DA 9000 caliper and enve 2.0 fork.

  • They generally turn a blind eye but they can fine you 20 EUROs-- 25 if they feel someone was endangered and 35 if you got into an accident. The law demands that you have "at all times" working lights (including reflectors). On random controls and dragnets (usually in the Spring when the masses haul their bikes out) they tend be on the lookout for standard push-bikes and supermarket MTBs but if the officers don't like the way you look or ride and "suspect" that the bicycle is perhaps unsafe...

  • Awesome, you'll enjoy it, feel real smooth on the straight and confident inspiring in corners.

  • New Corsas were faultless over a long weekend in Flanders. Great over the cobbles but to echo Ed they really impressed me through tight bends and descents. Confidence inspiring indeed.

  • What about continental sprinters?

  • Is there a comprehensive list of rolling resistance for TUBULAR tyres somewhere? All I can ever find is clincher lists.

  • YES! Braking all good? How wide are the tyres coming in at?

  • Have not measured. Can do later though. Braking is fine (wheels have the fancy new braking surface from enve), and you can take the wheel in/out with the tyre fully inflated with no probs.

    Laods of clearance at the bridge at the rear, but i dont think i'd get anything bigger in the rear direct mount caliper.

  • absolute winner!

  • rolling resistance for TUBULAR tyres

    You can't really test them. Most of the tests remind of bicycle testing in consumer reports. How often have bicycles with identical brakes and rims gotten different results in their braking power?
    Tubular tyres are too difficult to test. There are just too many variation in roundness of tubular tyres and the state of their rubber. The best ones are, afterall, handmade. Relevant to their rolling resistance is not just how round they are but how well they are mounted and with what adhesive. Some tyres just mount better-- straighter-- on some rims. And even in the hand of an experienced mechanic things are never really consistant enough to set a baseline. And the glue? Using tape-- as some tests have done-- results in significantly higher rolling resistance. The difference in rolling resistance between using a stricky road mastic and a strong adhesive such as Terokal 2444 or even old-school shellac is highly significant. And what inflation? Again different tyre constructions are better at different inflations.
    To test tubular tyres one would need to have a number of random samples of each model, a number of different rims and use a strong adhesive. One would need to also plot inflation, weight and rolling resistance. One would probably have to repeat the testing over time to see the influence of age and wear on rolling resistance-- older somewhat worn tyres are known to have lower rolling resistance. One could then throw out the singular samples and talk about "typical".. Frankly why?
    But to the question about the Sprinter? They are OK.. Current ones are even much better than old ones.. Just don't get the Gatorskin..

  • Re: sprinters

    1) are they fast?
    2) how do they handle?
    3) are they as hard as other continentals tubs to get on the rim?

    Asking because they seem reasonably priced

  • Sprinters are ok... but feel like their clinchers. Conti tubs are hard(er) to get on, although they benefit from stretching. They're far more durable than Veloflex/Vittoria etc though, so fine if you're training (or commuting on tubs).

    On a good set of wheels for summer days I'd probably want one of the high TPI tubs though.

  • Has anyone used Vittoria Open Triathlon Evo clincher?

    Picked it up new off eBay for about £7 and thinking about using it on the front of the TT bike.. Not a bad price for 320tpi @ 190g

  • ) are they fast?

    What does fast mean? The new ones use Black Chili and have great grip and roll nicely. The older ones were not bad either..

    2) how do they handle?

    They handle OK.. They are not as consistent as the Competitions.. and perhaps not as robust but still quite robust.

    3) are they as hard as other continentals tubs to get on the rim?

    Yup. They have nylon cords. The main difference between the Sprinters and Competitions are they they are a bit less consistent, a bit heavier and provide less puncture protection... The new competions have not just Black Chili but also a Vectran belt--- like the GP4000s clinchers. The older Competitions had a Poly breaker but were also "hard as nails"..

    Asking because they seem reasonably priced

    Yes. In my opinion the absolute cheapest tubular tyre worth buying. For under 35 EUROs they are great deal.

  • You're only allowed to ride them at threshold. It's a bit like that film Speed - they explode the minute you go 1w over your FTP.

  • That's alright then, I'm always under FTP

  • I dont even know what FTP is.

  • File Transfer Protocol.
