When I built up our last touring bike I could not find a set of 9-speed Shimano bar ends anyplace, or even a set of 8-speeds to use in friction mode untill I could get some. I tried new and used, E-bay, Gregs list etc. with out luck. What I did find was a N.O.S. pair of Sun Tour bar ends, and I installed them. Thinking I would just swap them out with a pair of indexed bar ends when I could get them.
But I don't miss the indexing, so Im not going to bother. The old shifters work fine with the 9 speed so why bother.
"When the spirits are low, when the day appears dark, when work becomes monotonous, when hope hardly seems worth having, just mount a bicycle and go out for a spin down the road, without thought on anything but the ride you are taking." - Arthur Conan Doyle
