XX1 Eagle™ weighs about 1590 grams for the complete drivetrain. This is in the neighborhood of 50 grams more than XX1. Given the performance and range increases, this is a small price to pay. The complete X01 Eagle™ drivetrain weighs about 1625 grams. About 60 more than original X01. It’s worth noting that Eagle™ groups are almost 300 grams lighter than our competitor’s equivalent groups.
