Subject: Mount V-brakes to a Disc-only frame?
|
I'm trying to build up a "cheap" bike to use my old bike parts.
Adding a disc wheelset/brakes defeats the purpose of this exercise.
Most of you will just tell me to use a different frame...but has
anyone tried adding V-brakes/bosses to a disc-only ALUMINUM frame?
Can it be done? Are there 3rd-party add-ons (i.e. bolt-on bosses), or
is welding an option?

Why don't you use long reach caliper brakes instead? No need for bosses.

Proper post welding heat treatment is not exactly a do-it-yourself
proposition.
I rode a bike for a while that had linear pull brakes mounted on an
older version of this adapter, fastened to the fork blades with

There's always that $50 Nashbar steel mtb frame--now with free
seatpost. :-D It's the cheapest option, actually.

Use a different frame.

I haven't tried this, but you might be able to use a BMX adaptor plate:

You bolt the top to the seatstay bridge and attach the lower tines to the
seatstays with hose clamps. I don't know if they're the right size to work
with mountain bike frames.

I'll have to look into this. There's a frame or two I'd like to try it
on. I'll have to see if any of my local stores have it on hand and
could measure the drop for me. Alternately I suppose I could email Dans
comp.

AFAIK, welding Aluminum effectively requires special atmospheres and
extraterrestrial know-how. It's not something you can get bubba at the
Earl Schieb to do for a six pack of Olympia. And if he did manage to
get the bosses on there, would you trust them?
Some basic cable discs are going to be far cheaper than finding
somebody with six fingers that can do this properly.
