Hi, just bought a second-hand bike with Sram Force standard 53/39 and 11/25 cassette, can I replace the Sram cassette for a shimano ultegra 12/30 :?:

Yes should be no problem, I have ran ultegra with RED no problems

The cassette will fit and will work no problem - the only issue will be whether your current rear mech will cope with the 30t sprocket...

And if the Force rear mech is not WiFli then it probably won't cope with 30t sprocket.

12-27 is a good one. Not sure but I think 28 is the largest it will "officially" take.
