Next-Gen Frame Take on any challenge with a frame that won't let you down. Developed alongside South University Aluminium Research Institute, the XDS X6 Ultralight Frame is a top-tier hydroformed frame that uses the stiffest aluminium composition to bring you one of the lightest, highest-quality frames available. Manufactured with a rigid fork, this bike is one of the XDS' lightest MTBs. Take Control of Your Ride Equipped with a 16-speed Shimano Altus drivetrain, the Strike can help you find the best gear ratio no matter what terrain you're tackling. The reliable front and rear Tektro hydraulic disc brakes keep you in control when tearing down the inclines.
