MTB Groupsets, Drivetrain Bundles & Upgrade Kits

Refresh worn parts or plan a drivetrain upgrade with groupsets and bundles from SRAM and Shimano. This collection includes small shifter-and-derailleur bundles, electronic upgrade kits and more extensive groupsets. Pick the package that covers the parts you actually need.

Check What's Included

A groupset name doesn't guarantee a crankset, cassette, bottom bracket, battery or charger is in the box. Read the component list for each bundle and compare it with the parts you plan to keep. Check drivetrain speed, cassette/freehub compatibility, derailleur mounting and, where relevant, crank and bottom-bracket fit.

SRAM Eagle and T-Type Options

Compare conventional Eagle drivetrain bundles with Eagle Transmission T-Type groupsets. T-Type includes both AXS electronic and mechanical options such as Eagle 90; it doesn't automatically mean wireless. SRAM Full Mount Transmission requires a compatible frame built around the UDH interface, so confirm your exact bike before ordering.

Our SRAM Eagle comparison covers the earlier Eagle tiers, while our XX T-Type long-term review looks at that Transmission setup. The GX Eagle review guide is another useful reference.

Shimano Drivetrain Upgrades

Explore the Shimano options listed here, including XTR and Deore XT Di2 upgrade kits. Our Shimano drivetrain comparison explains the established tiers, and our XT M8200 Di2 overview covers that wireless generation.
