That means lifetime warranty on the frame. They can offer that warranty because very few break. They do carbon fiber bikes better than anyone. You may not want to tell them you had SS'd it if you do happen to break it. I considered it myself and even found out I could buy it as a frame only. I ended up going with a custom steel 29r for about the same money. I do think it would make a very sweet bike with an ENO rear wheel and a bling light build kit. I'm thinking sub 20# probably pretty easily.synkronized23 said:I was thinking of getting a Trek 9.8 carbon frame and converting it into a singlespeed. Do you think it'll hold up? How strong is the 9.8 frame? What do you guys think? Thanks.
