    Hi all,

    Having just managed to snap(!) the pivot arm off my front caliper (Promax Render-R), I find myself in need of new brakes.
    The brakes would be going on a 2015 Cannondale Caadx Tiagra, so 160mm front and 140mm rear discs.

    I’m thinking something like Shimano CX-77 or am I better off going for something like TRP Hy-Rd?

    Cheers!

    If you are using ‘wavy’
    If you are using ‘wavy’ rotors – ditch ’em. You don’t need mud shedding on a roadbike, and the wavy cutouts just create noise and weaken the feel. Fitting Hayes continuous rotors over the standard TRP wavy ones made a huge difference.

    And yes, both were set up correctly and burnt in.

    Should have ’em fitted tomorrow, so I’ll keep you posted :)

    Had a couple of rides on them now. All good. Really powerful (compared to the Renders) and lever throw doesn’t seem as bad as many reviews seem to make out.

    Thanks again for the help and advice everyone.

    My fault, didn’t read your message properly!

    That link seems to suggest that it is a bad idea to run 140mm discs… I ended up getting the Hy/Rds because there is a 140mm option for those (couldn’t find them in the UK, but found them on a German website).

    The cx77 (and BR517 : same
    The cx77 (and BR517 : same brake different paint) work very well in my experience. Downside is that they need 3 different sized ale keys to adjust them but otherwise they Re effective and low maintenance. Regarding the rotor size, that is mostly determined by the mount on the frame so if you have a 140 on the back then it shouldn’t be a problem. You can use an adapter to size up To a larger rotor but not down.

    Apparently the Juin brakes aren’t compatible with 140mm discs, although I can’t think of a reason why that might be!

    It could be that the calliper offset is sufficiently large that the pads don’t contact a 140mm rotor even if they’re bolted directly to the mount without an adapter.

    “However, am I right in thinking that the Hy-Rds are worth the extra dosh?”

    I got fed up with adjusting BB7’s and despite being a bit cynical about a combined cable/hydraulic system I ignore my unfounded prejudice in favour of all the good reviews – my opinion was well worth the extra – you get a lot more performance than the extra cost – feel similar to full hydro on my MTB

    Don’t leave your bike upside down though – I did after getting a lift home with it wheel less on back seat – next day there was a horrible whistling noise when turned the right way up – checked and apparently they do vent to the air and will suffer if left upside down

    EDIT ***as above on the Juin (which get good review) need to check if will work with 140mm, mine came with 2 x 160mm rotors possibly because that’s what I ordered or it may be no 140mm option**

    I’d love to but I’m not fancying stumping up £silly on levers as well as calipers.
