I'm investing in new cranks. I want something bomb-proof and high quality. I don't ride track, but I do up to 30-mile rides on some rough roads. I also weigh 250.
All my research says Sugino 75's are my best bet... super stiff, reliable, high bang-for-buck. Given that... is the regular Sugino 75 chainring beefy enough? Is the Zen substantially stronger, in a way that would benefit me? Or, are there other, better options I haven't considered?
