Ugh so I have a SRAM cassette?!
I got bored and took my back wheel off my Trek 1500 which is a grab bag of 105,Ultegra and Tiagra. As I was cleaning the cassette for the first time i notice right on the black plastic ring on the front of it in big letters it said SRAM! What the hell? This bike was supposed to be all Shimano, I don't really care that its a SRAM product as much as it means i have SRAM compatible wheels right? So if I buy a new set of wheels I have to buy a new cassette if I want shimano compatible wheels, or am I totally wrong on this.
