The IRD thumbshifter is a shortened Silver ratchet shifter, so it should fit onto the IRD stem mount just fine. But you might be able to skip this step altogether and just mount your shifters-with-clamps onto your quill stem. The diameter of your clamps and the stem mount is the same, so just put a wrap of cloth tape around the stem and slide them on. This will be a bit clunky with two shifters - and I'm not sure how the cable angle will work - but should work fine with just one.
Keeping the front derailer without a shifter will work if you can get the limit screws adjusted to hold it in place over the big ring. Or you can ditch it so you can stop and put the chain on the small ring for that inevitable big hill. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
