Chain Length for Two Different Cassettes
I currently have an 11-28 and am getting a new 11-23 and chain. I'm holding onto the 11-28 on a different set of wheels as a backup set or for when I ride hills I can't do on an 11-23.
If I size the new chain for the new 11-23 cassette (using the Park big-big +2 method) will it be too short for the 11-28? Is there a happy medium? Or do I have to size for the largest?
