There aren’t many times a replacement part actually improves your bike but put one on your bike and you’ll wonder why you didn’t install a NINJA sooner. The bearings are housed in an alloy shell and wrapped with plastic and fibre. This fusion of the three materials provides the bearings a solid platform to sit on and extends their lives. A lot of people would be satisfied with this, but they went even further by extending the alloy shell so the right and left sides lock together. This locks the frame, cranks and bottom bracket together and provides unparalleled stiffness.

From the lung-busting efforts of hilly cross-country mountain biking trails to the constant accelerations of cyclocross races and through to the pain of lactic acid in interval training, the XC5 (XC502) MTB SPD Shoes deliver as much of your hard-earned power through to the pedals. And this premium performance comes at a less than premium price point. For racers on a smaller budget, they're a brilliant choice. S-Phyre Technology The design of the XC5 shoes makes use of Shimano's S-Phyre philosophy and features, as first seen on their premium cross-country race shoes. It starts with the foot-wrapping upper, offering a snug fit that provides a supportive pedalling platform and removes hot spots. Made with a durable synthetic material, this supple upper is incredibly light and highly breathable too, perfect for warmer weather and challenging hill climbs. The upper construction is also integrated with the sole unit, as first seen on the S-PHYRE XC902, offering extra support and stability during hard off-road efforts. Power to the Pedals With their glass-fibre reinforced midsole, the XC5 balance the need for optimal pedalling efficiency with value for money. Rated 6 out of 12 on Shimano's stiffness scale, this sole unit gets your hard-won watts to the pedals but with enough flex to take the buzz out of rough trails. A low stack height gets your foot closer to the pedal axle, improving efficiency and foot support still further. Shimano's ULTREAD™ compound also features. This sticky rubber sole, in combination with the grippy tread and lug pattern, provides a firm grip when you're off the bike and running loose and muddy terrain. You can also fit Severe Condition Spikes (not supplied), just right for the muddiest of MTB and cyclocross races. BOA® L6 skeleton dial Low-profile, light in weight and offering precise adjustment, the BOA® L6 skeleton dial lets you quickly and easily get the fit, feel and security of the shoes just to your liking. It's also easy to make adjustments on the go - tighten them up for a final sprint - loosen them off as your feet swell in the heat. Cleat Guidance These MTB shoes are compatible with MTB pedal systems, which use cleats with SPD standard (2-bolt standard), e.g.: Shimano SPD, Time ATAC, CrankBrothers, CrankBrothers Race, Look MTB, Xtreme MTB, Wellgo MTB, Ritchey MTB.
