SRAM XX1 Eagle Boost AXS 12-Speed Groupset

When building up an XC Mountain Bike with a Boost axle platform, the SRAM XX1 Eagle Boost AXS 12-speed Groupset is simply the perfect addition. Lightweight componentry, a massive gear range and completely wireless shifting technology make this a top choice for riders of all abilities.

The SRAM XX1 Eagle Boost AXS 12-Speed Groupset is at the pinnacle of wireless shifting technology. This lightweight group of components delivers a drivetrain that shifts accurately and delivers your power superbly. Use the SRAM AXS App (with a compatible smart device) to wirelessly set up the shifter exactly how you like it. You can even use your TriggerShifter to control a SRAM AXS Reverb dropper seatpost too, sold separately.

The 1x crankset is a trail-proven, dependable drivetrain component at this stage, and opening it up to a 12-speed set up makes it all the more versatile. With a 34-tooth X-SYNC™ chainring combining with a 10-50 tooth 12-speed cassette, you can enjoy a massive 500-per cent gearing range; perfect for riding up, down and across hills on the most challenging XC events. The Rainbow Chain adds a flash of colour to the setup too.

The impressively lightweight rear derailleur shifts instantly and accurately and features an innovative Overload Clutch, which disengages the gearbox in the event of an impact. The result is less risk of damage to your derailleur from taking a knock while on the trails.
