Brake/Chain Clearance

(1/2) > >>

Wayne Ryder:
 I think there's an expensive goof happened at Chez Moi. Finally, all the pieces were in place, so the 13t freewheel went on, the 36t sprocket (complete with homemade solution to the lack of top-hat spacer) went onto the crank and the tyre was moved to the new wheel. The chain was shortened to the appropriate length...
And only then did the problem of the chainstay-mounted rear brake let itself be known: It rubs.
The brake's a Dia-Compe X-CE or something, and the only spare I have is a Hombre. There's no significant height difference to speak of.

 So what (decent) brake's got the lowest height so that the chain can run freely? It's only a couple of millimetres, if the chain's kept tight, they'll never clash again.
 Anyone had any experience of grinding down the 'nut' and bolt on a 990/Hombre slightly?

motomagII:
mine was just and only just catching on my evolver i stuck a puncture rubber patch on the brake so it didnt do any damnage when rudding every now qnd then is was okay for ages

TwoBobRob:
Hombre's are only a cheap thing anyway, and Billy's will sell you any spares you might need..... so.....

Get grinding!!!   ;D ;D ;D


It'll be fine as long as you can still get the allen key in for adjustments and stuff.

Wayne Ryder:
I suspected it'd be OK, but wanted to make sure no-one came out of the woodwork with a shocked expression and some horror-story about what would happen. Or, 'You don't wanna do that, you wanna buy one of those £50 CNC brakes."
At the moment, that's not really what I wanna do -at all.

evamedia:
Never understand why they put the brakes on the chainstay's , my old HAF was a nightmare, for brake clearence, chain length etc.

Seatstays FTW, unless of course you wanna do a cherrypicker ;)
