    SRAM Eagle drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Its 1x drivetrain is built to be lightweight, strong and intuitive, with the gear range to ride on any terrain.

    GX Eagle provides the best choice of materials and finish options and remains fully compatible with SRAMs Eagle groupset.

    Sonder Alpha 27.5"

    Alphas are our performance 27.5" wheelset for big hits and big tyres. Whether you're riding down Top Chief at Fort William or riding the black routes at Bike Park Wales, Alphas will consistently spin up to speed and keep rolling to help you ride with fluid precision over the trails.

    Alpha's have a boost hub for strength and stiffness and wide rims to improve tyre performance. They're built for abuse with sealed bearings and are tubeless ready.

      Features

      Progressive geometry

      Long reach, low bottom bracket and slack 65° head angle for bucket loads of confidence. 425mm short chainstays for agility and insane acceleration out of turns.

      Hand welded 6061-T6 triple butted frameset

      Not all tubes are equal. Transmitter uses tube walls of different thicknesses to get material where it is needed and save weight where it isn’t.

      Geometry and Sizing

      Sizing

      It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height.

      Generally we recommend:
      Small: Riders between 5ft 2in and 5ft 7in (157-170cm)
      Medium: Riders between 5ft 6in and 5ft 10in (167-177cm)
      Large: Riders between 5ft 9in and 6ft 2in (175-187cm)
      X-Large: Riders of 6ft 2in + (187cm)
