Carbon fork life expectancy?(2 posts)

Recent threads about carbon forks have gotten me wondering.

I have a Time Vectran fork, which has been on my Litespeed Ultimate since early 1994. I figure it probably
has about 8K miles on it. Steel 1" steer tube, of course, as that's all there was back then. I haven't spotted
any cracks or noticed any problems, but I'm just wondering. I'm sure these things can't last forever, unlike
the steel forks on my other bikes, and I'm wondering if I'm heading into any problems. These days, I use this
bike almost exclusively for racing and crit. practices.

I've seen recommendations that ultralight handlebars, helmets, and various other parts need regular
replacement, but I haven't seen anything on this topic.

Any thoughts?

Check out the fatigue testing shown on the AME website. Several forks shown will fail in as little as 100,000 cycles, the minimum to qualify. Several, like a Time, and of course, the AME product are still ready to rock after 250,000 cycles. (My old Time fork was as good as new after eight years). Several are shockers which might lead to a really paranoid feeling of a major faceplant! The AME Alpha Q fork is the best out there IMO. www.alphaqfork.com
