Moving Brazed-On Cantilever Studs

[Question Man]

All -

Is it possible to have a frame builder move cantilever studs from the
postion for 700C wheels to the position for 27" wheels?

Is there any risk in the structural strength of the seat stay when
doing so? That is, when the studs are taken off & then re-brazed, is
the overall strength of the seat stay affected?

The bike is an old steel Raleigh, by the way.

Thanks!

Phil

It won't be a problem for a properly equipped framebuilder. He may
choose to use new studs. The structural strength shouldn't be a
problem. I suspect you will find when talking to the framebuilder,
that he will indicate a small possibility of failure, just to cover
his butt. Assuming a steel frame, it should be trivial for a competent
person.

If you really want to go from 700c to 27" (a dubious expedient imo),
it should not be difficult to find "tall" cantilever brakes that will
gain the extra 4mm in height. Some cantis have a lot of vertical
adjustability - e.g. certain Pauls, Avid Tri-Aligns, and some Tektros
that look like less fancy versions of the Avids. Going from 27" to 700c
is harder.

I just had the studs moved down (27"-700) on my touring bikes forks. Had
lowrider bosses installed too while it was there. It's actually a very
simple process and quite inexpensive.

The folks here turned me on to the idea and now I can use stock
linear-pulls on the front as well as on the rear. Dopn't need my (and
Sheldon's) Macgyverism anymore.
