Another question for 11.4 about chainrings (sorry for dragging this one out!)
Since a DA 7710 crankset is going over my budget, and I would probably most likely want a DA 7710 to match, what's your opinion between the sugino zen trackring and Shimano's 7710 chainring? How would they compare? Would I be able to mount sugino 75's on a shimano 7710 chainring since they are the same 144 bolt pattern? I'm thinking of going with Sugino cranks since a sugino BB will be included with the frame. Mind you, I will be using the setup on the street as well as occasional track use...
They're both superb chainrings -- the best of what's out there these days. They both have sophisticated tooth profiles that are quieter, last longer, and are the most efficient. You can't go wrong with either of them. And yes, all 144 BCD chainrings and crankarms are interchangeable.
