Thanks for the thoughts on these shifters. I doubt I will be running anything more than a 7 speed freewheel or cassette so I think these are just what I need.
I like the idea of the bar ends. I know I have a few extra and I am pretty sure I have some x-mart bikes that have them I could steal from. The other good thing would it would give some people another hand position since its not like these bikes are going to fit everyone that well. For the tall people I plan to put some straightbars on a couple big Schwinn Varsity bikes and just roll with the stem shifters. Its tough to improve on those for this purpose.
Anymore thoughts would be great.
