Both cassette CS 5700 (10 speed 11-28) and the rare mech have 2500km on them.
I always track millage of my parts so it is accurate and this means they have plenty of life in them.

Both need a proper clean and will serve for many more miles.

I swapped to the 11-32 cassette therefore rare mech had to be replaced as well, hence reason for selling both.
