    We the people ... Done it: Mtb rapidfire shifters on drop Bar

    Hi Everyone,

    I thought I'd share a recent project I did on my commuter.
    I've been using downtube friction shifters on a 8 speed Freewheel but the shifting was annoying requiring constant trimming. On the lowest geat, the lever sits almost parallel to the ground which snags my shorts.

    So I thought about upgrading to a pair of STIs or bar ends. I don't like bar ends and STI are $$ so I came up with a cheaper alternative. I decided to mount a pair of rapidfires on my drop bars.

    People have tried unsucessfully because the clamp Dia (22.2 mm) of the shifters are too narrow to fit over drop bars (23.8 mm).

    I used Shimano STX-RCMC38 Rapidfire because it has a removable and meaty clamp to work with. A few minutes of sanding on the drum sander and Voila!

    I'm quite pleased with the results. She works perfectly on the SunRace Freewheel
    Here's how it looks.

    Nice work.

    Alternately you can just use a large flat blade screwdriver to spread the clamp a bit wider and slide it on.

    Absolutely
    But the newer style clamps are much thinner with the pod/clamp and the brake lever integrated in one assembly.
    Some people have tried just spreading the clamp but ended up cracking and ruining the entire assembly. Even Sheldon did this!

    A beefy clamp is ideal for this application. If it breaks, just replace the clamp.
