SRAM GX Eagle AXS Boost 12-Speed Groupset

This SRAM GX Eagle AXS Boost 12-Speed Groupset includes the GX Eagle AXS upgrade kit, GX Eagle solid pin chain, XG-1275 Eagle cassette and GX Eagle Boost 148 DUB Crankset, so you have everything to upgrade your MTB setup. Pairing the rugged durability of GX Eagle with the proven technology of AXS, these components bring wireless electronic shifting to more riders. 

Shifts are instant and precise across the 10-52-tooth cassette, and the rear derailleur with clutch technology prevents chain slap and drop. SRAM Overload Clutch protection means that when an impact is detected, it disengages to safeguard the derailleur and then returns to the original position. The chain runs smoothly and, together with a X-SYNC 2 profile to the chainring, gives you complete control. 

Eagle technology offers an expanded gear range of 520%, helping you spin and recover as the trails point up. 

Pair the system with the AXS app and customise it to your preferences. Change the way in which your components work, personalise controls and view the remaining battery life from your phone.
