im running a 36 ring with an 11-34 cassette and it's perfect for my riding. I will be going to the sunrace 11-40 or 11-42 cassette soon- just to give me the lower end I might need for bike packing. the cazaderos are ok...but I miss my nanos. I'm waiting on a pair to arrive. I won't be keeping these. they're too squirmy on the road.
