I'm looking to buy a power meter, the most affordable options right now are both Stages, a Dura Ace 9000 (450CAD), and an Ultegra 6800 (400CAD) crank arm, both used. They both use Hollowtech II pinch bolts so there isnt an issue in compatiblity- Is there a very noticeable performance difference in terms of weight, and stiffness between the two options?
Also in the market for a new Garmin/cycling computer, one with power, and heart options, live Strava segments, and SMS are cool but not really necessary if you guys could share your experiences and preferences!
