Bell XR Spherical Helmet (MIPS)Comfort, protection and low weight meet in perfect harmony with the Bell XR Spherical Helmet (MIPS). For cyclists who seek superb function and streamlined design, it's hard to beat. If you love to mix it up in the frenetic atmosphere of a race pack and love to push your fitness in training, the XR Spherical Helmet (MIPS) ensures you have the finest level of protection should you get caught up in a crash. Thanks to its Fusion In-Mould construction, the XR Spherical is strong, durable and reliable at soaking up head impacts from a crash. The progressive layering of both inner and outer EPS foam layers gives shock-absorbing protection against both slow-speed and high-speed impacts. This delivers a more comprehensive level of protection than standard helmets.Meanwhile, the polycarbonate outer adds structural strength, allowing Bell to reduce weight and increase vent size without compromising protection levels while also adding durability. MIPS® Spherical TechnologyWhen it comes to advanced head protection it doesn't get much better than the MIPS® Spherical Technology. This ball and socket system is designed to reduce the rotational forces of impacts to the head. This is achieved via the dual-layer system whereby the helmet outer is able to rotate around the inner liner during a crash. MIPS (Multi-directional Impact Protection System) The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head.Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head.Float Fit™ Race (integrated with MIPS)This minimalist fit system ensures you can quickly and easily achieve the most comfortable fit of your helmet. The easy-to-turn dial features an over-moulded rubber grip so you can operate it easily, even on the fly. And it's light too - always a win for performance cyclists. Feature-packed Performance With its 18 vents, you can be confident you'll always have a rush of cool air over your head. And when you do build up a sweat, the Sweat Guide™ system at the brow moves sweat away from the bow pad and prevents it from running into your eyes. Ionic+ Comfort Padding also fights the build-up of bacteria, preventing itching and maintaining freshness. A Fidlock Magnetic Buckle makes it quick and easy to put on and pull off your helmet while No-Twist Tri-Glides™ make sure adjustment straps are always in the right place and kept flat.Features:Fusion In-Mould Polycarbonate Shell with Progressive LayeringSpherical Technology powered by MIPS®Float Fit Race SystemIonic+ Comfort PaddingFidlock Magnetic BuckleNo-Twist Tri-Glides™Sweat Guide™18 Vents including Overbrow VentilationCertified to CE EN1078Weight: 285 grams (size M)Shop all MIPS helmets - Click hereBuy Bell Helmets from Chain Reaction Cycles, the World's Largest Online Bike Store.

Leatt MTB Gravity 4.0 HelmetThe Leatt MTB Gravity 4.0 Helmet is an award winning, downhill ready helmet. With a host of safety features, it will give you the confidence to push your mountain bike riding to new heights. When you're on your DH mountain bike and squeezing out every last ounce of speed things can go very wrong very quickly. A misjudged line. A high-speed washout. A clipped handlebar. Perhaps too much speed into a big booter. It's during those living on the edge moments you'll be glad of the protection of the MTB Gravity 4.0 Helmet.Impact Protection PerformanceThe Gravity 4.0 boosts confidence thanks to its host of protective features. The heart of the 4.0 is a dual foam construction, featuring EPS + EP0 impact foams. In combination, these two foams work hard to soak up the forces of both slow and high-speed crashes. The foam inner is covered by a tough Polymer shell, enhancing structural strength and durability. And for particularly gnarly trails, the 4.0 is fully neck brace compatible.The visor not only keeps off sun and dirt but in the event of a crash, it's also designed to break away, reducing the effects of rotation force impacts. You also have a removable mouthpiece ventilation cover - leave it on when you want extra protection, pop it out when ventilation is more important.360 ̊ Turbine TechnologyThe Gravity 4.0 also features Leatt's 360 ̊ Turbine Technology. This tech is focused on reducing the damaging effects of a crash on your brain. It works via 360 ̊moving discs, all made from an energy-absorbing material. These impart a reduction of rotational acceleration to the head and brain by up to 40%. The system also improves the absorption of impact energy - it reduces peak brain acceleration by up to 30% at the impact speeds associated with concussion.Ready for DH ActionWhen you're getting rowdy, you're sure to feel the heat build. But that's not a problem. The Gravity 4.0 has a total of 22 air vents, creating a rush of cool air to the head when you're up to speed. This keeps fresh air circulating and allows warm sweaty air to escape.Talking of sweat, the Dri-Lex® liner is quick to wick moisture off your skin, leaving you feeling drier and more comfortable. The anti-odour treatment also prevents nasty niffs, ensuring you're not causing a stink on the uplift. And to keep that always fresh feel, it's easy to remove and wash.Lastly, with its Fidlock magnetic closure system, it's super quick and easy to pull on and remove your helmet. Less fuss. More riding.Features:DH certified lightweight Polymer shellMaximized ventilation with 22 ventsRemovable mouthpiece ventilation coverFidlock magnetic closure system360-degree Turbine Technology - Reduces forces associated with concussionDri-Lex® moisture-wicking, breathable, anti-odour and washable inner linerOptimal neck brace compatibilityVisor with breakaway function for rotational reduction in a crashIn-moulded EPS + EPO impact foam for superior energy absorptionWeight: From 850g Certified and tested: EN1078Buy Leatt Protection from Chain Reaction Cycles, the World's Largest Online Bike Store.

Replacement axles exclusively for Profile Z Coaster® hubs. Hardware shown on axles (jam nuts & cone spacer) included.
Profile 14mm Titanium Rear Hub Axle. This is a conversion kit for Mini, Totem, and Madera V2 Cassette from the 3/8" 3 piece axle to the 14mm Gun Drilled Hollow axle. It will also work with the High Flange hubs. It will not work with the Elite BMX hub. It contains a GDH CrMo axle, non-drive cone spacer, and locknuts.
Profile Racing’s Titaniun 14mm GDH CASSETTE HUB AXLE answers the call for strength and weight. It’s CNC precision machined and lighter than standard steel axles by almost half yet it’s just as strong.
