Should You Use A 1X, 2X or 3X Drivetrain For Touring and Bikepacking?
Eight years ago, SRAM released the first 1X-specific bicycle drivetrain. I remember Nino Schurter winning on it within weeks of it being shown to the public, which was an early sign that 1X was going to pave the way for drivetrains to come. Fast forward to 2020 and 1X drivetrains feature on a large percentage of bikes. According to my Bikepacking Bike Buyer’s Guide, it’s two-thirds of all 27.5″ gravel bikes, and close to 100% of mountain bikes. So, are 1X drivetrains now the ultimate drive system, or is there still a place for 2X and 3X? Today, we are going to analyse every aspect of bicycle drivetrains. We will be looking at all data available across eight different categories to find out once and for all, which drivetrain is best. 1. Drive Resistance VeloNews has lab tested the resistance of both 1X and 2X drivetrains, and the conclusion is clear: 2X is the most efficient across all gears. The main reason for the higher resistance is greater cha.... Continue Reading at Cycling About
