The Speedplay Zero road pedals are uniquely qualified to withstand the demands of everything from all-out racing to the epic endurance rides. The stainless steel dual-sided bike pedal and integrated cleat system offer peak power transfer and exceptional durability. The customized fit and dual-sided entry will allow you to crank on the pedals in confidence and comfort.Wahoo Speedplay pedals are designed for road cycling only. For the best riding experience, ensure your cleats are clean before and during every ride. Off-road cycling can result in damage to the cleats and/or debris becoming lodged in the cleats.Speedlay Zero symmetrical form factor allows for dual sided pedal entry when clipping in. No more fumbling, fussing or kicking your pedal over; take off when the light turns green and clip in with ease. The slim profile cleat and rubber texture create enhanced stability when walking in your road shoes off the bike.Speedplay Zero pedal and standard tension cleats create a seamless integration for a streamlined profile. The secure connection can contribute to an increase in the transfer of power, which can make it easier to attain those hard fought watts. The standard tension cleat can be positioned on the bottom of the shoe and adjusted fore-aft, left-right and rotationally, allowing between 0-15 degrees of float. Speedplay pedals allow up to 15 degrees of float, allowing the heel to pivot around the center of the pedal. This range of motion in the foot, lower leg and knee increases comfort and enhances pedal efficiency.The slim profile of the Speedplay advanced pedal system allows for the greatest degree of lean on the bike when riding tight corners. Pedal with confidence knowing your pedal won't strike the ground, and leave the competition in the dust.Cleats are included.

Thule's range-topping fork mounted carrier, ideal for avoiding frame clamping and is their most universal roof carrier. Its adaptor design ensures a perfect fit and easily guides the axle home with a rapid, secure clamping procedure, important when you have the bike held high This carrier includes adaptors for 100 mm Q/R, 12 x 100 mm, 15 x 100 mm and 15 x 110 mm, adaptors for other sizes available separately. Plus, it features an axle clamping lever that closes with an audible click and a clear visible indicator so you know 100% that your bike held securely in place.
What's most impressive about this new version is it doesn't make contact with your bike's frame and instead uses a strong hook which securely grabs your front wheel and a ratcheting wheel strap for the rear. Suitable for bikes weighing up to 20kg, it makes loading and unloading your ride extremely easy thanks to Thule's simple interface design.
Repente saddles with more traditional shapes like this Comptus model have been designed with the nose area typically narrow so there are no issues from legs rubbing on the edges. Also, the unique design of the monocoque shell offers just the right balance between rigidity and flexibility. In order to maintain the supporting function of the nose Repente work with the highest quality padding and their research and experience allow them to judge perfectly the quantity of padding to avoid any rider discomfort. All Repente saddles take into account the conventional anatomical centre to position and shape: 1) The best point of contact of the ischium bones (sit bones) for comfort and also the ideal position for performance 2) The outline shape of the front of the saddle gives freedom of movement to the legs
Loaded with features certain to have you grabbing it with both hands, the Super DH MIPS Helmet is the ideal companion for those looking to negotiate hours of uphill climbs, bike park laps and non-stop grinding in their session. Sporting a 360-degree wraparound, uncompromised protection from everything the trail has to offer inspires confidence in your ride. With a tool-free removable chin bar that easily dominated the rigours of ASTM 1952 testing, the goggle-friendly eye-port and adjustable height visor allowed for customised protection on the go. Should the intensity rise, Overbrow Ventilation and X-static padding improve breathability and enrich comfort, resulting in uncompromised performance. With an integrated breakaway snap-in camera mount offering up the opportunity to film your sick skills, the Super DH MIPS Helmet is the only protection you need when kicking back and nailing the challenges set in front of you. 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.

In addition to the reliable Shimano gears and strong wheels, this capable hybrid bike comes with Suntour NEX suspension forks. With 63mm of travel, they soak up vibrations and sudden impacts that would normally make your ride uncomfortable or make you lose control. This results in a smooth and enjoyable ride over mixed terrain, mile after mile. This model also has a dropped top tube, making it easier for on/off transitions. Technologies: A2-SL Butted Aluminium Fuji's mid-level aluminium and most widely used frame material which has a double-butted profile in the frame tubes that reduces material in low-stress areas and creates a lightweight frame that is extremely durable. Endurance Geometry Fuji models with endurance geometry feature a taller headtube and longer chainstays that put the rider in a more upright riding position and increases bicycle stability. Models with endurance geometry still provide a fast and spirited ride but without the discomfort of an aggressive race posture. Internal Cable Routing Cables are routed inside the frames tubes for improved aerodynamics, longer cable life and a clean aesthetic. Rack Mounts Strategically placed braze-ons are ready to accept most aftermarket racks, further increasing the utility of your bike. Disc Brakes For All Models Disc brakes take less effort at the lever for better modulation and improved braking performance, particularly for smaller hands. Built, Tuned and Ready to Ride Rest assured that each bike is fully built and tuned by Wiggle's team of qualified bike mechanics to ensure your bike arrives in perfect condition. We supply all bikes with a set of plastic pedals, a pedal wrench and a multi-tool kit. Find out which size fits you by clicking the size chart tab.
