It doesn't seem to be that much of an expense. 100 or under. Esp if I change it out myself. What do u think?
No.
If you have an 11-25 10 speed cassette and replace it with an 11-25 11 speed cassette, your high (fast) and low (slow) gears remain the same. You just get one more increment in-between, which for a serious racer, might have the benefit of disrupting their pedalling cadence less when changing gear. Also, the adjustments are finer and potentially more fiddly.
