Thank you all for the great responses and ideas. Here are some more questions based on those... - I had not considered the alternative of going to a triple crankset; initially Mark suggested to keep the double for the lower Q factor, but I don't know how much of an issue that would really be for me. I never have any trouble with my triple crankset on my mountain bike. However, this option brings up the following issues: * Need to change the bar-end shifters, the Sram won't be compatible with the triple crankset - not a big deal... * Will the 10 speed chain work smoothly with the triple crankset that is designed for 9 speed or fewer chains? 10 speed chains are narrower - conversely, will a 9 speed chain work on the 10 speed cogset? I don't think so, it might get stuck as the space between the cogs is narrower as well...
That would mean, if I got it all straight, that probably the best solution would be to go with a triple crankset and a regular Shimano 9 speed cassette and other standard parts. Sell the Shimano Rival drivetrain to a roadie looking to upgrade to 10 speeds (I have the integrated brake/shifter levers as well) and gain the flexibility of easily customizing a Shimano 9 speed drivetrain. Did I get that right? The kind of hills I want to climb are in the San Francisco Bay area... Highway 84 to Skyline, Old La Honda, Mount Diablo, etc. Some of them I could climb now, but on the brink of blowing out and that is no fun at all... :-) I'm going back to the calculator and craig's list... :-) René On Sat, Nov 14, 2009 at 6:17 PM, Richard <[email protected]> wrote: > > Sorry about thinking you can get a Shimano 10-speed cassette in the > range you want.
