I want to lower the range of my Cyclocross bike drivetrain and use larger tires. The SHIMANO DEORE FC-M590 48-36-26t 9-speed crankset has the right combination of chainrings, but I want to keep my 10 speed cassette, chain, front derailleur (105 5603 triple) and STI-Brifters. I'll use a chain guide-retainer to help avoid a dropped chain.
I'm not looking for fast and flawless shifting, but I would like the sytem to shift smoothly within one turn of the crank. Can this combination work well enough, or is a 9 speed crank not going to shift well with a 10 speed chain?
