Gear Ratios: Comparing 2×10 versus 1×11 Mountain Bike Drivetrains
Curious how switching from a 2×10 drivetrain to a 1×11 group like XX1 will affect your gearing? Thanks to Scott at Switchback Bikes, wonder no more. The chart above (click to enlarge) shows how the different XX1 chainrings with that oversized 11-speed cassette stack up, helping you choose the right front chainring(s) for your riding. It was used on their website, by way of a forum post by Daryl Smith.
