Does anyone use this gearing setup? Ken Kifer wrote about it, saying he liked a 10% difference between his top two chainrings. His setup sounded pretty useful, with 14 out of 15 usable gears, but it had a 5-cog cassette, which I can't put on a modern touring bike. Does anyone know of a good setup one could put on a Surly LHT? I tried to create a 7-cog version of Ken's setup, but I'm not sure if an LHT will take 7 cogs:
* 42-38-24 in front
* 11-13-15-19-22-27-33 in back
At any rate, I don't know how well this would work, and into what combinations I would find myself unable to shift because of chainline issues. Should I just go with the flow and use individual gearing (something like the Surly LHT complete's setup)?
