  1. I have a 1995 Raleigh M60 with the Shimano ALIVIO derailleurs and a 7-speed cassette. The brake/shift combo (it's a one piece deal) is the ST-MC12 model. The right hand (1-7 speed) shifter is broken. You can can move the shift lever without resistance.

    My question(s): 1) Can these be repaired? I can't find any useful tech drawings. 2) If it can't really be fixed, can you still get ST-MC12s anywhere? 3) If I need to just bite the bullet and replace the ST-MC12 with a newer model, what model should I get? I'd like to avoid replacing or upgrading the cassette to 8 or 9 speeds because that would lead to other issues like hubs, derailleurs, chains, etc. I just want the shifter working and the left and right shifters to be a matched set (and maybe keep the repair cost under $75).

    Any help or suggestions? Thank you.

    1 - no
    2 - if its the one im thinking it is no, you'll have to get something similar but it should cost around $40-50USD for the shifter, mabie even cheaper.
    3 - whatever, depends what you wanna spend and what style you get

    is everything else on the bike alright ?

    Yeah, everything else on the bike is fine. Mechanically, fairly light wear. The paint job has taken the brunt of the wear. The whole bike needs a good cleaning and a tune-up.

  4. OK. So if I can't repair the shifter and everything on the bike is OEM and set up for the ST-MC12, then what model brake/shifter combo or brake and shifter separate will work on the bike (and not require that other components be changed out)? Will an ST-MC32 work, for example? Is there an equivalency table I can use?😕

    Thanks for your help.

  5. The MC-12 is a pretty common shifter/lever setup and almost all bike shops should have them in stock or something equivelant to it.

  6. Hi do you still keep the left hand shifting lever unit?

  7. You mean like these..............hurry before they're gone, lol..................Holy [censored] on the old thread revival,lol. Wonder if OP still even has the same bike.
