  • Cheers for the suggestions all :) Tempted to start a CP for my bikes and riding.

    Front mech doesn't shift well but think it is going from a 34-50 if that has anything to do with it? Don't know if it is 105 or tiagra. Also think my mech is a 105 RD5701, short/medium cage so don't confidently know how big I could go.

    Where can I find out what shifters will work with what mech? Think these suggestions cover me though. The chainset is an eyesore so may upgrade that, possibly something sugino and maybe a new front mech.

    @StevePeel cheers :) If I get space for a road bike may do that, do for some relaxed gearing here and front rack/basket. My rear mech shifts amazingly so shame to ditch it but hills loaded.

    @AlexD just enjoyed your thread! I moved to Bristol start of September, let me know if you want to do any riding!

    @cnnchi Tiagra 4700 (done some googling now) seems to be a solid/economical option

  • Hey, welcome to Brizzle! I ride with a local gravel group - I’ll pm you with details of that sounds appealing.

    There’s info regarding mech/shifter compatibility out there across many squillions of articles and forum posts.

    If you’re sticking to shimano, basically 9 speed road/mtb and also 10spd road is all the same cable pull ratio, (apart from 4700 which is different!) so is compatible (so, you can use a 9speed mtb mech with 10 speed road shifters).

    Then after that it all goes nuts and everything is speed and discipline specific.

    I know zilch about front mechs and only have one across 5 bikes so can’t help you with that :-)

    Edit: that looks like a GS (medium cage) mech to me - you can use that with a 32t cassette, possibly a 36t.

  • @AlexD cheers! yes please do that would be ace. Could it do 34 or are mtb and road cassettes different? Just started a CP thread as to not ruin the genesis thread!
