Shimano fc-m601 chain ring 34t?

[rvt1000r]

I was wanting to install a little larger set of chain rings on my shimano fc-m601 crankset. I was looking at putting a 24/34 instead of the factory 22/32. Anyone have any ideas what is compatible with this crank? Thanks

I *think* the bolt circle diameter (BCD) for those is 104mm for the larger ring and 64mm for the smaller. Any chainrings you find with that spacing should work just fine.

I’ve always had good experiences with Race Face’s chain rings:  http://www.jensonusa.com/Chainrings/Race-Face-Turbine-10-Speed-Chainring?cs=Black

Try checking to see if the BCD is printed anywhere on the chainrings or the crank itself. It may be in very fine print, but many cranks and chainrings should have the measurements on it. I ran into a heck of a issue with not having the right BCD crank for what I wanted to do just the other day: I had two cranks that were the wrong BCD, when I needed a 104 as Aaron mentioned.
