I have a set of wheels that will be here soon. There are tandem wheels with Shimano hubs, 145mm rear, Shimano 9 speed compatible. I'm wondering, I have 3 9 speed Shimano cassettes in my parts drawer. One is a mountain setup with a 12-30 something, the other 2 or road cassettes are 11-21 and 11-23.
Can I combine parts of 2 different shimano cassettes to come up with a range I like?
I was thinking something like 12-28?
Are road and moutain cassettes swapable if your deraileurs are long enough?
