SRAM Red Crankarm Trade?
 

Not quite sure if this is the right place to do this but I was hoping to trade SRAM Red Crankarms locally in Northern California. I have a set of good condition 175mm crankarms that I would love to swap for some 170mms. In addition, if anyone happens to have a compact red crankset that they're willing to trade for a set of 175 standards, I'd be up to do that as well.

Good luck. If you succeed, I might try posting something similar, offering to swap S-works 172.5 crankarms for some 170s. :)

thanks no luck yet but we'll see
