This is my first post so forgive any indiscretions. I'm just at a bit of a stop on a chainring replacement for my Cannondale F600. I currently have a FSA V-Drive MegaExo crank on it and I was wondering if I could change the front rings from a 44-32-22 to a 46-36-22 without any clearance issues. I've been riding it a bit on the road and flatter more downhill terrain so I was wanting to try out a bit of a different setup. Is there anyway I can measure or estimate the size of the new chainrings to see if they'll fit my frame or will any 104 4-bolt ring work on it?
I honestly don't think you'll notice the difference between a 44 and a a 46. If your rings are wearing and you need new ones, by all means, replace them. Otherwise, its probably not worth it, the change is less than one tooth worth in the back.
