Groupsets / Drivetrain Bundles

Showing 73 products



If you are looking to upgrade your drivetrain, buying a groupset or drivetrain bundle is one of the smartest ways to do it. Instead of piecing together individual components one at a time, you get a matched set of parts that are designed to work together right out of the box, usually at a better price than buying everything separately. These bundles typically include a rear derailleur, shifter, cassette, chain, and sometimes a crankset depending on the kit. The two dominant brands are SRAM and Shimano, and both make groupsets for mountain bikes, gravel bikes, and road bikes across a wide range of price points.


On the SRAM side, the Eagle lineup is the gold standard for 12-speed mountain bike drivetrains. Starting from the top, you have the XX1 Eagle and X01 Eagle at the high end, the GX Eagle as the sweet spot for performance and value, and the NX Eagle for budget-conscious builds that still run 12-speed. SRAM also has their wireless AXS and T-Type transmission groupsets for those who want to go fully electronic. Not sure which Eagle tier is right for you? We did a full SRAM Eagle groupset comparison that breaks down every level side by side.


On the Shimano side, the XTR, XT, SLX, and Deore lineups cover everything from race-level performance to solid everyday trail riding. Shimano also now has their Di2 wireless system with XTR and XT options for those who want electronic shifting without going SRAM AXS.
