I have a shimano tri color corncob on my touring bike, with an ovaltech triple. It ended up there by accident, after I broke the removal ears on the original freewheel. It was all I had on hand, so on it went. Since we don't have that much elevation here sans the occasional overpass, I rarely shift more than a gear or two. If I were to take it on a longer ride through the hills, I may wish for more gear, but that's what that granny gear is for. Sure I'll have to shift a few times to get everything lined up, but this bike isn't built for speed anyway.
