£15 - brand new and unused, but I used the box it came in to send some brakes off, so it'll come in a SRAM Cassette tub. As title says 13-26t,10 speed. ---NEED GONE BY TONIGHT OR I'LL KEEP IT--- This is a photo I took last week when I received the cassette, unfortunately I have to sell it to fund a new build. I paid £30, so you're getting it for half price. PM me if interested.
