If it was me really wanting to put bar ends on a trekking bar, I could probably make some adapter sleeves.
I also think I’ve seem some TT bar end shifters that go over - as opposed to inside - the bar. Shimming these to fit a narrower bar wouldn’t be that difficult.
A Sora front front derailer won’t index cleanly with a MTB front shifter.
Then there are Paul’s Thumbies, which would allow mounting bar ends on flat bars but in a thumb shifter position.
How do you feel about GripShift?
dabac,
That's a lot of great information there. I'm retired and don't work in an industrial setting any more, so making adapters and the such isn't an option for me. But you gave me some great info for things I can look into.
I've never used grip shifters to any extent but didn't really like them too much. They don't seem very durable to me...at least the couple that I tried.
Thanks, Tony
