Tubulars on Carbon rim vs Clinchers question(4 posts)

Tubulars on Carbon rim vs Clinchers questionhammer_cycle
Oct 15, 2001 5:05 AM
I've been interested in picking up a set of Zipp 404s for quite some time now, but since I plan on using them only for racing, I wanted to purchase the tubular version since they are lighter. On Saturday, my local shop had the 2002 clincher model in stock and offered me a great deal. The mechanic told me that the tubular rims are so smooth that it is very difficult to get the tire to glue properly to the rim. Has anyone had problems with tire rolling on all carbon rims? The clinchers are great rims, but they are a bit heavier. My goal for these wheels is to race them and not ride them on the local hammer sessions.

Thanks in advance for any insight.

I race on carbon Zipp 303 with Vittoria CX tubs with no problems. Don't know if your mechanic has a lot of experience gluing tubulars, but aluminum rims are "smooth" also. I have read reports that the adhesive bond is not as strong with carbon rims as with aluminum, but with proper mounting I have 100% confidence in my wheels. If these are race only wheels you should go tubular - the weight savings are significant.

Just make sure you take your time with the gluing process and use good quality glue. I use Vittoria Mastik with one coat on the base tape, two cured coats (12 hours each coat) on the rim and a third coat on the rim just prior to mounting.

I own a set of Zipp 404 tubulars. I have not experienced any problems with them at all. I agree with the other poster in regards to the comments your mechanic said about these rims. I have bombed down mountains in excess of 50 mph and not experienced any tire roll-off problems. With this wheelset, you get the best of both worlds, lightweight and very aero at the same time. By the way, you may want to contact Charlie at www.empirebicycles.com for a great deal on a set of Zipps. That's where I bought mine for $775. Hope this helps.

I have been using 440's for about 1500 miles. No problems.
