Cindy’s Featherweight Cross Bike

August 27th, 2012

Cindy is one of the luminaries on the Bikes Not Bombs-Circle A Cycles ‘cross team, and for this season she wanted something with a better fit and lighter weight. Something to win on. She’s not tall, and was eager to engineer in some toe/tire clearance. This is what we came out with.



The frame consists of a True Temper S3 front triangle, with Dedacciai rear triangle featuring Zero chainstays and Zerouno s-bend seat stays, and weighs in just a tick over 3 lbs. The fork is by Enve. I’ll be building a steel rando fork for her as well, so I’ve included rack and fender mounts. Putting the “light” in light touring.

        

The S3 tubeset is a bit tricky to work with; only the seat tube is round, and the extremely thin walls (.5 mm at the butts!) make it easy for it to tear in the mill, so every miter is done by hand. And they have to be tight if I’m not going to burn through while welding. Also the small size of the frame demanded a funky compound miter at the head.

     

Next: Dan’s single speed MTB, Charlie’s ‘cross machine, Bert’s rando rolls!
