My Avid BB7 are in the bin, looking at new brakes. What options do I have?

Keeping Avid levers, staying with cable
or hydraulic set

front and rear 16cm rotors
Say... That's a nice bike..

    flat bar or drops?

    If the former, then you could stay with Mechanical and go with TRP Spyres, or go the whole hog and change to hydraulic.

    I've just replaced the front BB7 with an XT hydro and the difference is positive; no more squeaking (esp in the rain) or adjustment, with just the right amount of power when you need it.

    flats. What about this set?

    I have the rotors from BB7 and the Tektros before them, plus mounting from the Avid BB7's

    Looks like a good price for the set, I also used the BB7 rotor and mount for the replacement brake and it worked fine.

    The only issue I had was hose length and had to shorten the hose to make it work. This looked to be a bit of a faff and without a vice time consuming, so asked the LBC to do it for the princely sum of £9.

    I got the next level up from Merlin for about another 25 quid - superb brakes. Difficult to say what the difference is with my previous but the Shimano XT brakes really do fill me with confidence

    It all depends what you want...

    Mechanical are mostly heavier (although mine on my Gryphon are lighter than many hydraulic) need more frequent maintenance but are easier to maintain.

    Hydraulic will be a bit more expensive and more powerful (mostly), require less routine maintenance but when needed is a bigger faff.

    For a commuter you don't need anything flash have you considered the Shimano trecking options? Such as http://www.chainreactioncycles.com/in/e ... at=product
    Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.

    That's £5 more expensive than what has already been suggested, as it's per brake

    I'm ok with mounts and those M615 I won't need to buy another set?

    brakes arrived but it seems to be euro method, right is rear, left is front! So when I get them shortened I have to flip the hoses around

    having problems fitting, mainly the front one- the avid disc mount doesn't seem to match up. Just putting on the caliper on the mount, the inner part of the brake hits the mount. If I flip the mount, the lower part of the caliper internal stops out I cannot push the caliper onto the mount.

    I'll have to take it the bike shop I think

    pretty sure I need this

    Getting the hoses shortened involves removing the hose from the reservoir, so swapping them round shouldnt be an issue. I specifically ordered mine to be front brake on the left, as I wanted to keep the RH shifter....I just have to remember which bike I'm on.

    I had no issues using the post mount from the BB7for mine but not like for like, as mine's an XT....good luck.

    just bought offical shimano 160mm front IS mount. Fingers crossed should fit
