I really could have used this last weekend at the slopestyle, but here is a quick little 31.6mm pivotal post. My dropper post is 2-3" taller than this and prevents this hardtail from being a good dirt jumper. The added standover makes for a much better rocky terrain DJ bike.
Sand bike in the works. Just waiting on 100mm BB shells and some RaceFace cranks
some V brake posts and a disc tab for Dave's polo fork
