I'm buying a new wheel and new freewheel. I was just going to get a 20t freewheel to go with my 32t ring (don't laugh it's the ratio I ride OK!) :D :D :D

I have a nice Blackspire 36 tooth ring and I thought that maybe a 22t would work nicely with it. So. IF i've done the math correctly the 32/20 and 36/22 give me about the same gear ratio. Is there an advantage or disadvantage of doing it either way?

If you ride over a lot of logs, rocks and other obstacles, the smaller ring will give you a touch more clearance. If you ride farther distances and smoother trails the larger combo will wear longer and have a (probably imperceptible) bit less mechanical resistance. The bigger combo weighs a touch more, if you are a WW though. Nothing wrong with a 32 x 20 if you ride hilly or techy terrain. I ride a 33 x 20 on my 29'er and when I was starting off I wished I had a 32 x 22! As I got stronger, I sometimes want to put a 19 on the rear, but there are still a few really steep hills that I fight to get up with the 20, so it all works out. If I am going along the flats or down a hill, I just spin what I got, or coast!
