I just got this
bike and so far I think the 11-28T cassette is a little too wide of a range and would like something with closer steps. The problem certainly could be (probably is) me and not the cassette as I'm not in shape yet but I also like to tinker and fix things that don't need fixing.
Now according to the spec sheet on my bike I have a Shimano shifter and chain, SRAM cassette, and Xero hubs. There obviously must be some sort of standard in place for all these parts from different manufacturers to work together, but I'm assuming there must be limitations to these standards as well.
Based on suggestions I've gotten from another thread I think I'd like to try a 12-25T cassette. It would appear
according to this
site that I happened across that my stock SRAM is compatible with most Shimano equipment. The c-c spacing is the same but the cogs on the Shimano are 0.02mm thinner which sounds like a very small difference to me plus already having a Shimano chain I don't anticipate any compatibility issues in that respect.
At this point I'm eyeing a Ultegra 6500 12-25T and aside from the mentioned compatibility worries, I'm also unsure about quality. These apparently have something called "Hyperglide" which says it provides smoother shifting. Does my SRAM have the same "technology" but by a different buzz term or is the Ultegra better? My SRAM from time to time (not sure if it's specific to some combination but usually when shifting down) tends to jump and gives me a little jerk. Not a big issue but I'm really trying to baby my knees as I've had problems in the past so anything smoother would be welcome.
