changed the feel of my bike for the better. enjoying the different ratio i feel faster and more efficient. works well with my old group set and frame. couldn’t have asked for much better in a product for this price.;

Probably the least expensive 7-gear cassette 11-24T. I am very happy with it replaced by 12-21T cassette without difficulty. 12-21T is too narrow a ratio having 24T makes my hills (in central Florida) much easier. Shifting is smooth.;

My old Trek 930 is now used exclusively on the road and the old mountain bike gearing was much too low for comfortable riding for me at least. The shifting has improved over the old Shimano cassette. I'm pleased with this low cost upgrade. 12-24t;

Remarkably light in weight it works very well.;
