This Ultegra 10 speed cassette (12-23 ratio) has been used on a race wheel for approximately 2 years. A couple races this year, a few last. It’s in very good shape. $50 shipped. Ready to ship today
Also have a similar cassette which was used on a training wheel for the same period (approximately), so it has more miles (how many? I don’t know). Bike was recently tuned up, and mechanic said cassette was fine. $40 shipped. NOTE on this cassette - I THINK it’s a 12-23. I don’t have it at the office with me (I have the other one, and counted gears). There’s a silight chance it’s a 12-25, but I think I remember using the same cassette on both wheels.
My standard policy applies: Buy it . . . if it’s not what you thought it was, send it back to me and I’ll refund the $$ (minus $5 or so for shipping)
