Sora 9 speed compatibility
I have a Specialised Allez Sport Compact with 9 speed Sora drivetrain.
Will this 11-26 cassette fit OK?
I want to keep the original 12-25 on my Winter wheels, and fit a 11-26 to my Summer wheels to give me a bit more top speed, plus extra help up the hills...
I don't want to start messing around with new derailleurs etc., so will this be a straightforward fit?
Thanks very much,
