Tubular Report: Greg Reain Method
Well, Croutch just won the provincials on the last set of tubulars that I glued, and they held up just fine through the last half of the season racing in dry, snow and mud. They were glued using the Greg Reain method plus a little extra:
- Vittoria Mastik One glue (this glue is a lot firmer than the Gommitalia)
- Three layers on the rim – the middle one quite thick
- Two layers on the base tape, one thick
- A last think layer on the rim
- Mount the tire when the glue is wet
- Mask the tire sidewall and the rim braking surface, deflate the tire, run a bead of glue in the crease between the rim and the tire
All told, 5.5 tubes of glue and four days for two wheels – Grifo tires on Ambrosio rims. I still don’t think the Ambrosio Excellence rims are the best rim for CX tubulars, but it all worked out. Croutch ran the tires around 35psi, and gave them rave reviews.

With you up to the bead down the crease, but you lost me on the masking. Good idea, thanks!

Stick electrical tape on the braking surface of the rim and on the side walls of the tire. I did this before gluing anything. It lets you get the glue right to the edges of the rim and the tape on the tire, without making a mess. When you mount the tire, the tape gets pulled off and there is a bit of a mess, but if you put electrical tape back on the braking surface and the sidewall, you can run a nice thick bead of glue down the crease, and then let it dry and peel off the tape – no glue on the braking surface….

Maybe I should take some pictures….

Jeez – I forgot about the masking. Hence all of the squeeling brakes for the last couple of weeks. Luckily I get to try again – a few more times I’m sure.
Also have this stuff now – Goo-Gone I think it is, seems to work well after the fact.
