jmaccelari Posted February 11, 2009 Posted February 11, 2009 Go for tubbies!...Here goes the thread... I have two sets of tubbies I use only for racing. IMHO, I think theyare the best thing to race on. It might also be the fact that they'rebonded onto Zipps, tho'... For training I have some Dura Ace clinchers. At least I can fix thepunctures and replacing tubes & worn/cut tyres is cheap. Different strokes for different folks...
shade Posted February 11, 2009 Posted February 11, 2009 and fyi, manufacturer TUFO , have designed and made a tubular tyre ,to fit a clincher rim ! claiming it gives most of the tubby characteristics ..

Speed Devil Posted February 11, 2009 Posted February 11, 2009 When choosing between tubby and clinchers at the time of purchase, the deciding factor is mainly price. Tubby rims are cheaper, especially when looking at full carbon, compared to their clincher counterparts.It is up to the individual whether they want to take the risk of running a flat on a tubby in a race and not completing the event, or paying a bit more and have peace of mind. Personally, I don't see how people can use the higher pressure rating of a tubby over a clincher as a deciding factor, as riders who weigh less, like myself, run a lower pressure to compensate for the harshness of the road surface.
gyro Posted February 12, 2009 Posted February 12, 2009 tubbys are crap (personal experience) -stay away! If you puncture, you are stuck on the side of the road. Sealant does not always work and then your expensive new tire is also trash.

Aaaah....Once again the voice of reason has spoken Reason......mmmm.....Oom Johan, like Christie and all other engineers, only trust in figures.Go ride it and FEEL the difference. That is it. Easy hey. I have done extensive research on the subject.... Tubbies can take pressure up to 14 bar.Tubbies puncture easy.The glue.gu/sh*t inside the tubbie does not seal the tubbie always.You pay R1 000.00 for a good new tubbie if you punctureIt has a different feel to clinchers Clinchers go up to 11 bar. Most of them up to 8.Clinchers (tube) can be repaired at minimal costNew good clincher costs R500The best Clincher has a better rolling resistance than the best tubbie out there. And yes, I have fact sheet etc.The average Clincher Carbon deep sections wheel weighs more than Tubbie Carbon deep section counterpart. There are two manufacturers that I know off that makes a light Carbon Clinchers. Lightweight and DT Swiss. Both of them costs over R25 000.00
AndreZA Posted February 12, 2009 Posted February 12, 2009 The "feel" term is not a selling point for me. The same as non of us mortals that race in the wonderfull super competative racing circuit here in SA can tell the differance between a R20 000 carbon and R10 000 carbon frame. Everybody just read something somewhere and relay it to someone else. Next someone is gonna say that Conti tubes are better the Kenda. BTW, Conti tubes are crap an my BBB is better.
slowtwitch Posted February 12, 2009 Posted February 12, 2009 Tubbies are better PERIODDon't tell me ALL pro teams run them just because of sponsorship issuesDon't you think they've got access to the best clinchers available anywhere? Now it's a different issue whether they're the best for your application/ budget/ following car (or lack thereof) etc. PS Speed Devildevil & Tibones, I cracked myself for your discription page 1
