Slightly over-thick cantilever post
I just got a new OTP Bob Jackson world tour, and I can barely force a canti brake onto the left canti post on the fork. Once I get it on, it doesn't turn very easily at all -- clearly unworkable.
My question is whether this is common, and what a shop/framebuilder might be able to do about this, or whether this is something that I should just take some sandpaper to.
The problem is not the brake, I tried a few old crap cantis that I have lying around, and nothing would fit (or at least not easily).
So, take it to a framebuilder? Johnny Coast and Brooklyn Machine Works are nearby. Would a reputable shop be able to handle this? Or should I try to sand it down? Any tips on this? What kind of sandpaper, what pitfalls to avoid, etc?
Thanks for tips!
