Flatting(5 posts)

This year i just got a new bike (used but new to me). 2 weeks ago i was racing in a tri and my front tire blew, 2 k from finish. I didn't have a spare inner tube, so i finshed (slowly) on the rim. I was wondering, what can i do to ensure it doesn't happen again?

Bummer! Glad you finished but rolling on the rims is a great way to screw up your wheels which can cost hundreds to repair/replace if they are nice (read fragile!). You could try using a heavier duty kevlar type tire to avoid punctures... change your tubes frequently especially in the weeks before a big race (but never right before, you might get a bad tube), carry a spare tube, a changing lever,a co2 cartridge, and an appropriate allen wrench if needed in a small under seat bag. The extra weight is worth it especialy if you get a flat on a longer course. my $.02....

I've heard that you can actually ride on tubular rims even when flatting, alot more than you can on clincers since the tubulars don't have as much...erh any sidewall rim like the clinchers do. Plus tubulars weight less.

If you are getting frequent flats I use a few tricks--Change you rim tape (I like Velox cloth tape) so your spoke nipples can't put pressure on the tube, change your tires if they have a lot of wear (if not make sure you check to remove anything embedded in the old ones), and you can try on of those protective strips you can get to keep punctures from getting through--heard "slime" works good too.

I flatted in three straight USTS races in 1988. I have never raced on clinchers in a triathlon since. Switched to tubular race wheels and(knock on wood) have never flatted in a race since. If tubulars are not an option, get yourself a high end clincher tire. This may help. However, I train on top of the line Vittoria clinchers and have still experienced pinch flats while on training rides. Good luck.
