SRAM Force/XO1 AXS Transmission Mullet Groupset Description:
The SRAM Force/X01 AXS Transmission Mullet Groupset takes the reliable and intuitive shifting function of SRAM AXS electronic wireless shifting, and combines it with the elevated durability and precision of a UDH-mounted derailleur design as well as the efficacy of SRAM’s T-type flattop chain and cassette. The exhilarating world of gravel requires not only the speed and confidence to stay with the pack, but sturdiness that can stand tall in the face of impact and turbulence; introducing select pieces of SRAM’s T-Type transmission MTB components raises off-road prowess, helping riders create their ultimate “go-anywhere, do-anything” gravel ride. This SRAM X01 UDH derailleur requires the use of a bike frame outfitted with UDH (Universal Derailleur Hanger) – check with your bike manufacturer or consult this page from SRAM for information regarding compatibility.
Note: Crankset/chainrings not included. Derailleur requires a UDH-compatible frame.
