I have a Rockhopper mountain style bicycle ,not an E bike. 20 years old.Generic but good. The 21 speed was always overdone and un needed. But I like the bike and want to keep it. I prefer to travel with that bike rather than the heavy cumbersome XP4.
The 21 speed has 3 discs. I was wondering if Shimano or others have a modern 10-12 speed now that will swap in and provide as good or better smooth service.A 2 disc unit. Anyone know of anything that might fit the bill..?
