SWAP - My (almost new) 12-27 105 cassette for your 11-15 equivalent

by pixelmix   March 26, 2012  

I have a 12-27 Shimano 105 cassette that came with my bike which I would like to swap for an equivalent cassette in 11-25.

The cassette has only done around 150 clean, dry miles and I would be looking for something with the same mileage (i.e nearly new) to match the rest of my drivetrain.

Thanks
