Yeah, I wonder about that last night. Hmm, I'll see what options I have. The problem is my MC21 forks are bent (not a huge amount, but still bent enough for me to want new ones). So getting new forks I either need to rebuild my R fork (with new stanchions), by used R forks, buy SP forks, buy RVF forks (easiest USDs) or mod other USDs to fit. I guess whichever is the cheapest will do at this point. I might just use my MC18 forks for now since they're in good condition.
