I mostly ride on trails that require 2000 ft of climbing for every 10-12 miles ridden. I’m currently on a 32T oval. I’m almost always in the 51T cog in the back for climbs. I make most of the climbs - but my cadence is really slow on the tougher climbs. There are a few tech climb sections that I just don’t have the power to get up.

I noticed my friend is riding a 30T Oval and he’s a stronger rider than I am. He’s in the 3rd cog off the 51 most of the time.

I’m trying to decide whether I should go 28T oval or 30T oval. What do you guys think?

Bike is a Canyon Spectral CF7, 29er.

Thanks
