OK, my old 7s hyperglide cassette is giving up the ghost, I have several "Crunching" moments on almost every ride. I recently bought new wheels, Shimano WH-M505, yeah I know heavy, but so am I and they are supposed to put up with daily abuse, so that is what I got. My bike is a 1988 Cannondale SM500 MTB, that I only ride on the road now, I use it to haul my trailer around doing deliveries for our liquor shop.

Now I have this for gearing... Front: 28T 36T 48T Rear: (7 speed) 13-23T (12,13,14,15,17,19,21,23) I'm looking at this cassette... View attachment 657 View attachment 658 8-speed 12-25T (12,13,15,17,19,21,23,25) This is the "W" group cassette. Not a huge change, but a change. I understand that the 11T cog cassettes will only work with the Hyperglide Compact I would not mind having the lower gears for climbing with a full trailer, so the 12-25T looks good I also see a "V" group cassette 13-26T (13,14,15,17,19,21,23,26) I know it comes down to a personal preference, so what I'm asking is if this is "Correct" as in do these parts play well together. Cheers!
