SRAM XX Eagle Transmission AXS 1x12-speed Groupset

Item number: 91126

The XX Eagle Transmission AXS groupset by SRAM for an electronic 1x12-speed drivetrain on trail and enduro bikes

This SRAM XX Eagle Transmission AXS groupset provides the main components for an electronic, wireless 1x12-speed drivetrain on a mountain bike. You get a crankset, an electronically-controlled rear derailleur with AXS controller, a cassette and a chain, all from the XX series for all-mountain trails and enduro race tracks.

One of the special features of the Eagle Transmission is a derailleur hanger-free mounting of the electronic rear derailleur, which is mounted instead of the UDH universal derailleur hanger. The use of this groupset is therefore only possible on frames with this derailleur hanger. Direct mounting results in exact, tolerance-free alignment of the rear derailleur and an unprecedented harmony of rear derailleur and cassette. Adjustment bolts and limit screws are not required. In addition, the rear derailleur is designed to be extremely tough, so that it can easily withstand impacts from all sides and you can continue riding without any problems after a fall. Via the Magic Wheel, the lower derailleur pulley, the chain simply continues to run if a branch or something similar gets in the way. The AXS Pod Ultimate Controller can be mounted on the left or right side.
The XS-1297 cassette has one aluminium and eleven steel sprockets and offers a wide range with 10-52 teeth, whose gear jumps have been optimised compared to Eagle cassettes. The X-SYNC design enables outstanding shifting performance even and especially under full load. Thanks to cassette mapping, the gear changes take place along designated shift ramps, which makes the process extremely smooth. The crankset is lightweight and stiff thanks to the carbon arms with foam core and is combined with a Direct Mount chainring with 32 teeth. Like the cassette sprockets and derailleur pulleys, this is precisely matched to T-Type chains. The XX chain has a special flattop design reminiscent of road chains, but specially designed for Eagle Transmission. It is particularly durable and features a hard chrome finish and weight-saving hollow pins.

A battery for the rear derailleur and a charging device are included. Use the groupset together with the AXS app to set it up, fine-tune the shifting behaviour and make and view other settings.
