I've been putting barcons on all of my bikes and even a couple sets for friends. It seems I'm not the only one, as the price of Suntour ratchets seems to be in the low 30's lately.

I saw that Rivendell had some adaptor pods that let you add your own DT shifters.

Unfortunately the mint Suntour power ratchets I have will need a longer mounting bolt (I'm working on it) but they don't feel bad at all with these friction Suntours. The longer levers seem to help make up for the lack of a ratchet.
