That is an interesting comment
francophile . I have a co-worker that doesn't like Cannondale or at least their crazy forks because you have to go to a specialist to get parts or repair it. He thinks Cannondale kind of went off the deep end and started making proprietary things so that you'd have to come back to them.
I don't think that was their goal, but it didn't hurt either. I like the HeadShock or at least the design of it, however, I don't think I would ever spend the long cash that these things are going for. Same with Lefty forks.
The design itself is simple enough. A square with roller bearings. But getting it rebuilt??? $$$.
So, good find. The best of all possible outcomes. The frame and wheels look great. It should turn out to be a fun ride when you are done.
