MTB groupsets

MTB drivetrain component sets from the bazaar are the best way to comprehensively and affordably upgrade the shifting, chain, and cranks of your mountain bike. In the bazaar, you'll discover complete 1x12 and 1x11 sets from premium manufacturers like SRAM (GX, X01, XX1 Eagle, Transmission) and Shimano (Deore XT, SLX, XTR).
What's important to consider when choosing an MTB set from the bazaar:

• Package content and completeness: A complete set includes a shifter, derailleur, cranks with chainring, cassette, and chain; verify the presence of all bolts and connectors.
• Compatibility with the rear hub freehub: SRAM Eagle requires an XD freehub (except for NX/SX cassettes for HG freehub), while 12-speed Shimano cassettes require a Micro Spline freehub.
• Type of crank bottom bracket (DUB vs. Hollowtech II): Check the diameter and length of the crank axle (standard DUB or 24 mm axle) and the chainline (Boost 52/55 mm).
• Mechanical vs. electronic wireless shifting (AXS): SRAM AXS wireless sets eliminate cables; when purchasing, verify the functionality of the battery, charger, and the condition of the derailleur motor.
