I've invested in 13-15 cogs for the past year and now is the time to buy some chainrings. I currently have a 48T Campagnolo and a 50T Zen, I'm looking to get a set (46,47,49) so I'm trying to keep the unit cost to a minimum. My options are: FSA's Pro Track wich cost $55 and they seem to be the best cost X benefit so far. Other options are the Sugino 75's for $98. Miche and Stronglight are also a possibility.
Can you guys help? Are the FSA's the best option? Is there another ring I missed?
