For Sale: High Sierra Syncronizer cranks. If you use them- you already know what they are. Cranks specialy designed to work with High Sierra rings for various strength/power differences.
I have at least 3-4 set of both 172.5 and 175 syncronizer cranks. Also have 172.5 and 175 adjustable syncronizer cranks (allows you to move chanring configuration around). Also have mountain bike triple syncronizer cranks. Make offers on any of it. This is a good opportunity to outfit multiple bikes if you only have 1 set.
