Here is my project.
21" Chinese carbon with 2x10 system, hope to finish under 10kg.

Building a Carbon Rigid 29er 1 X 10. The build it finished and comes in at 16.90 lbs but the rigid fork has a split in the steerer which was noticed right after cutting the steerer. Lucky that I caught it while doing the install and not later while riding. Lets see how well they look after this issue.

Screw that, I'll either take a Lefty or stay rigid! You go man (jbbikerider)! All 4 bikes look sweet as hell. Still loven' the BS though!

BTW, I'm poor so I'm still rigid.
