Superb, with a few challenges for compact chain ring sizes
I love these chainrings rings, and hardly noticed they aren’t round when first trying them. Great for long climbs, I find the spot is 85-95 rpm. Have also used Q-rings but prefer these.
In 34-50 the front mech set up is very fiddly, and you really have to want to use them to get a set up that works. The chain line changes so much per pedal revolution that getting no chain rub in biggest to biggest has been impossible for me. I think it’d be a bit easier with less size difference per chainring, say 36-50 or 38-50/52. But even with this small limitation I stick with them I have 2 semi torn knee ligaments and on round rings I need to rest up after a hard day’s ride. On the Osymetrocs I’m fine and can ride the next day.
