re-brazing canti bosses
I have an old lugged touring fork i want to use again (frame broken). The problem is that it's for 27" and I want to have the bosses rebrazed for 700c. I am wondering whether this will compromise the strength of the fork legs.
did you try a 700c wheel to see if it would work without modification? Seems a shame to ruin a paint job for 4 mm in spacing.
It shouldn't be a problem to move canti bosses assuming it is well done.
yeah the pivot is too close to the pads. It can be made to work, but it's tweaky, goes out of adjustment easily and not very powerful.
that's too bad. I am afraid I'm going to have to do this with my tandem if I want to change sizes. I also would have to respace the massively overbuilt rear triangle, so that's on the back burner for now.
What about these guys? It would seem they would move down the 4mm required to adapt, and you would get more power, These can be a little finicky on touring bikes if the wheels go out of adjustment, but mine don't so I would try them. You could ask them what they would recomend and what kind of lever would suit.
That said, 27" wheel are a pretty good choice for touring. Just look up any article on why 29ers are the salvation of the wheeled world and all the same arguments may obtain. Walmart sells a folding Bell tire for them that comes in a number of treads, where you find it, and the smoother ones seem pretty good to me. I was toying with the idea of building a 27" wheel touring bike. I was also like 700C, and 26". So far 650B hasn't called me.
Relocating the braze-ons is easy and safe. Done properly it will not affect the strength of the tubing. It is probably a good idea to grind off the old bosses rather than heating them. It takes quite a bit of heat to unstick brass brazed parts.
