Try this...very evenly spaced ratios...deraileurs don't have any huge jumps ...the near 1:1 low was plenty for a loaded touring rig on the transamerica route back in the day before "grannys". On a lot of cranksets, these three rings can be the s ame BCD which simplifies maintenance and it really does have a road bike feel to the shifting.

I am now the proud owner of the Black 1983 Bruce Gordon that was briefly discussed on this list a while back. I would sing the praises of the listmember who made that possible, but I recall such things may be against the rules. He knows who he is and if ever I can return the favor I would i n a heartbeat. This bike proves Dale's observation about black bikes. It does not photograph well, but in person it is very, very nice.
Loking at a 1981 Catolog, this frame is the Bruce Gordon Racing model. Probably not a custom build. My intention is to build it up to take my older and slower self over the more challenging Colorado passes. But I wan t the bike to still be true to its self. So, I am wondering what the list thinks would be a good setup functionally and asthetically. Also, with 6 cogs and a triple, what are the best ratios? I tried the archives with minimal sucess. Except on a mountain bike I have never run a triple.
