Some advice about this would be much appreciated.
I have an old '87 stumpjumper that I love, but it has under chainstay U brakes.
They're annoying to adjust and get clogged up with mud (not that I've given it much mud action recently). They also hit any ring over 42t.
What I want to do is remove them and graft some canti mounts on the seat stays, but is this safe?
I know it's not designed to have cantis but I figure with these older bikes it doesn't matter as much as it's essentially tough old gaspipe. Will the U brake mounts be safe to have lopped off and filled? Better to leave them on? Bearing in mind I won't be doing any of this myself - I just wanted to see if the idea was pie in the sky before I gave a framebuilder a ring.
Many thanks in advance.
Thanks @laner for the photo
I’ve just dropped a frame to Stayer cycles to have exactly this done. He said it was fine.
Is it worth it for how much its going to cost to have done and painted?
Small chainring 1x, wide range cassette is what I'd do
How much you reckon it'll cost?
Not gonna get it repainted, just want the cantis.
It's a 6 speed and cassette choice is very, very limited.
That's good to know, cheers
He quoted £45 to add new rear canti mounts + remove old ones.
Will just he chop off the U brake mounts and sand down?
Did you get new cable guides too?
Yeah I wasn’t bothered about aesthetics so no paint finished, no filling on the u brake and I’m going to run a v brake so will just use zip ties.
Needing new cable guides is the perfect excuse to treat yourself to a shiny new Mapp torch.
Last time I welded something was in 2008, and it wasn't pretty.
