View Full Version : MTB brakes: going hydro to cable question...

Call me crazy, but I am retrofying my 29er, by going rigid and putting my 7 spd Deore XT on it :) My one concession is that I am using disc brakes, but in keeping with my vintage Ritchey love, I want to use my Ritchey Logic canti brake levers and some Road BB7s, although hydros are far and away better.

My question is: is there an adaptor to allow the use of cable actuated brakes on a frame with guides for hydraulic (a closed line) brakes only?

There must be, but I don't know who makes them or how they'd work. When I switched to hydros from BB7s on my now departed 26er, I bought $5 worth of little adaptors that clipped into the cable brake lines - but now I need to go the other way.

Any suggestions?

Thanks!

Run full length Housing?

Yup.

Also, use BB7 roads or other road pull mech discs and you won't have to use weird cable pull converters. Spyres, etc, whatever.

OK, but what does it pull against? I guess the stop at the brake lever?

I found this, but damn, those are ugly.

Just run full housing and use the hydraulic guides.

Depending on what kind of guides the frame has on it, something like this might work.

Yep. Plenty of bikes use full length shift housing. Same concept. Try and use compressionless housing though.

Will do. As it turns out, I somehow have about 20ft of compressionless housing in a bag right now - not sure why - maybe a shelved project that I had forgotten about ?

Too much stuff, but that worked to my favour this time :)

Just confirming what others said. I'm running full length Jagwire compressionless housing with mechanical discs on an XL frame and it works very well.
