  • Saving you £15

Whether you’re an enduro racer or an all-mountain ripper you need a wheel that delivers the perfect balance of strength stiffness and lightweight agility—so you can push it on rowdy descents and still hammer up climbs with efficiency. The Deemax Pro weighing just 1810g gives you the confidence to nail new lines and carry more speed on technical downhill terrain. It was developed with input from top pro racers including 2017/2018/2019 Enduro World Series champion Sam Hill.  The rims are lightweight yet also strong enough to withstand the abuses of hard-charging trail riding. Our innovative ISM 4D manufacturing process removes any unnecessary material from the rim. This process minimizes weight and reduces inertia while leaving enough material on the sidewalls and spoke bed where most of the stresses apply. The internal rim width which affects tire shape and size is 28mm based on the choice of our pro riders. The result is a wheel that’s strong and light for acceleration and control on the most aggressive trails. The wheel is laced with 24 Zicral spokes for maximum power and brake torque transfer. The rear hub features our fast-engaging ID 360 freehub and is compatible with any drivetrain setup. The front hub is 15x100/20x110 or 15x110 (Boost) compatible and the rear wheel comes in 12x142 or 12x148 (Boost). Key benefits Ultra-responsive ride quality. 28mm wide (internal) rims proven fastest through extensive testing with top pro enduro racers.

Kink Williams Frame Flat Black / 21.25"
  • £349.99

The Williams frame is Nathan Williams’ first signature frame from Kink and features modern street geometry while retaining a classic look. But still the frame features several subtle details that should not be overlooked. The steeper 75.5° headtube is responsive, and the short 12.75” chainstay length makes the frame nimble without compromising on tyre clearance; fitting up to 2.5” tires. The double butted toptube and downtube with gussets on both ensure plenty of strength in the front end while the chainstay and seatstay bridge designs allot for generous tyre clearance while adding as much stiffness as possible. Nathan’s frame of course comes standard with integrated seat post clamp, integrated chain tensioners to keep the wheel in place and removable brake mounts. Additional details like the custom seat stay bridge badge inlay and interior dropout knurling round out both the good looks and serious functionality of the Williams frame. .embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; } ###section### Product Specs MATERIAL: Full 4130 Chromoly HEAD TUBE ANGLE: 75.5° SEAT TUBE ANGLE: 71° CHAIN STAY LENGTH: 12.75" BB HEIGHT: 11.7" WHEEL SIZE: 20" STANDOVER HEIGHT: 9" DROPOUT SIZE: 14mm HEADSET TYPE: Integrated BB TYPE: Mid BRAKE MOUNTS: Removable (Included With Frame) GYRO TABS: Removable WEIGHT: 4lbs 15oz ###section### Product Highlights Responsive Geometry with Short Backend and Steep Headtube Great all round frame for all types of riding Built in chain tensioners Wide rear end for extra tire clearance Removable brake hardware ###shogun-image-section###
