SWAP new Tiagra 12-30 cassette (10 speed)

[jasonmccullum]

I have a new (in box) 10 speed Tiagra 12-30 cassette but my rear mech can only take 28T

so im looking for a swap for a 10 speed cassette with a max tooth of 25-28

Thanks

I have the ultegra 11-25 that came with my bike originally? I put no more than 150km on it. Interested?
