I am about to put together an old wheel that I have with a trainer tire and a cassette for dedicated use on the Kurt Kinetic as the shorter days don't allow me to ride much in the evenings during the week. I have a SRAM Apex Group with the compact cranks and an 11-32 cassette as I have some pretty steep grades where I live. I was wondering if I should get a cassette to match the one already on my road bike? Or should I get an 11-23 as I won't be climbing hills on the trainer and will have a better selection of gears in the appropriate range?
I was initially leaning toward the second option, but I would like some other opinions incase I have forgotten to consider something. Thanks!
