DT Swiss PR1600 Rim Brake Road WheelsetFeaturing a high-quality aluminium construction, this road bike wheelset provides fantastic strength and reliability, at a wallet-friendly price. Ideal for performance-focused riders, this model comes equipped with a range of the brand's industry-leading technologies such as Tubeless Ready, ProLock and Bearing Technology. Performance isn't just about a number on your back and competing against others. It can also be about your own personal challenges. The PR 1600 SPLINE, available in 23mm rim height, is made for achieving your personal goals. There are a number of features that make this wheel ideal for getting maximum performance from heavy, powerful riders. The high-quality 350 hubs feature Ratchet System technology, while the 18mm wide tubeless-compatible rims are both extremely sturdy and very light thanks to the PHR nipple system. This wheel is a reliable partner for your next challenge and is bound to put a smile on your face the second your feet touch the pedals.Tubeless TechnologyTubeless tyres have a number of advantages over the conventional combination of tube and tyre: without risking snakebites, the tyre can be run with lower pressures providing better grip. The lower pressure also results in a more comfortable ride. Eliminating the tube means there is no friction between tube and tyre and therefore less rolling resistance when the tyre rolls over the ground and obstacles. If tubeless sealant is used, the tyre can self-seal stings and small cuts. A big advantage for all those who like to ride for long and far away from the next bike shop.ProLock TechnologyPro Lock is a process where a dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Re-truing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.Bearing TechnologyDT Swiss hubs are designed to function optimally once installed in a bicycle. To achieve this, the clamping force created by the wheel mounting system must be taken into account when constructing a hub.

Campagnolo Shamal Mille C17 Road Clincher WheelsetCampagnolo's Shamal Mille C17 Road Clincher Wheelset represents the premium standard in performance aluminium racing wheels. The chic surface treatment that gives this wheelset its smooth and smart dark look also represents a major performance improvement. This treatment allows sure-footed and sturdy braking power over and above normal aluminium rims, regardless of weather conditions.Enhanced PerformanceThe C17 rim ensures a better rim/tyre connection and an enhanced performance, especially when using 25mm and 28mm tyres. This stylish wheelset gets an upgrade by way of black anodised nipples to complete its minimalist dark look. The Shamal Mille is certain to have heads turning by both the competition on race day and those beside you at traffic lights.Features:Plasma Electrolytic Oxidation: It offers an elegant finish and enhances braking power and modularityToroidal Milling Spiral Groove on the Braking Track: Reduces braking distance while maintaining silent braking Differentiated Rim Height: Front (24mm - 27 mm) and rear (27mm - 30 mm)Dynamic Balance™MoMag: Allows the external profile of the rim to be free of holesAerodynamic Spokes in Aluminium: Maximum air penetration, less weight and greater reactivityDifferentiated Spokes: 16 radial spokes for the front, 21 spokes for the rear, doubled on the right and exclusive Mega-G3 spokes to reduce vibration, increase stiffness and transmission of power to the wheelBlack Nipples: Black oxidation finishing self-locking aluminium nipples outside the rim. Allows easy maintenance and less truing over the wheel lifetimeSpokes Anti-Rotation System: It keeps the spokes in position of maximum aerodynamicsCeramic USB Bearings with Differentiated Diameters: 28mm for the front, 30mm for the rear. Less friction, less weight, greater smoothness and the same performance over timeHub Body in Carbon: High lateral stiffness, reducing weight to a minimumAxle in Aluminium: Low weight, high stiffnessOversized Flange: It increases torsional stiffness, increasing its reactivity at every change in the cyclist's paceWeight: 1.459kgTechnologies:USB™ - Ultra Smooth Bearings: Hubs with USB ceramic bearings further enhance the wheels' smoothness and reduce weight and the need for maintenance. Comparative tests have shown that USB bearings are 50% smoother than standard bearings.G3 Geometry: Campagnolo has developed an assembly architecture which, compared with a traditional wheel, makes it possible to improve energy transfer, reduce the stress on the spokes on the right and increase transverse rigidity. This is achieved because in G3 geometry the right-hand side of the rear wheel is fitted with twice as many spokes as the left.The results of the G3 system are truly extraordinary: better transfer of the driving torque, better lateral rigidity, and reduction of the stress in the rear wheel spokes. Thanks to the G3 system that compensates for the forces acting on the 2 sides of the wheel, there are no more wheel vibrations, even for heavier people.MoMag™: A technology that offers several advantages to the structural integrity of the wheel as well as eliminating the need for rim tape. The name derives from “Mounting Magnet” system, shortened to MoMag.RIM Dynamic Balance - Aluminium Wheels: The concept is simple and elegant, balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint.Buy Campagnolo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
Campagnolo Bora Ultra 35 Clincher Wheelset Bora Ultra wheels are the choice of pros as they are the perfect wheel for competition. They offer you the performance characteristics that all racing cyclists are looking for - maximum aerodynamics, extreme lightness, lightning quick reactivity and incredible smoothness.Improved Braking in All ConditionsFor the Bora Ultra 35 Clincher wheelset, Campagnolo engineers developed an all-new construction, which has created a braking performance that far outperforms anything found on current carbon rims. The Campy Tech Lab’s developments focused on providing the rider with the same braking performance when riding in the wet as when riding in the dry. The result of these developments is Campagnolo’s most advanced braking surface technology ever. They call it AC3 (All Conditions Carbon Control).Increased Rim WidthCampagnolo has increased the rim width from 20.5mm to 24.2mm - this has not only improved the aerodynamics but allowed the wheel to accommodate wider tyres. Wider tyres increase control, improve grip and make for a more comfortable ride. A wider rim also increases structural integrity without any weight increase to the wheelset.Reduced WeightThe weight of the wheelset is also further reduced, thanks to the front hub having a smaller profile. Even though Campagnolo’s engineers managed to reduce the weight and size of the hub, they were able to save the same high-performance characteristics that the Bora Ultra wheels are renowned for.Features: Full Carbon high profile 35mm rim, in clincher and tubular versions. Includes brake pads specifically for carbon wheels AC3 treatment on the brake surface, improving braking in all conditions RDB (Rim Dynamic Balance) exclusive technology moulded inside the rims, assures perfect balancing of the rims even at high speeds Ultra-lightweight decals eliminate the need for heavy adhesives and painting, reducing the overall weight by nearly 15g Carbon hub with oversize flange with cup and cone CULT bearings, aluminium axle Aerodynamic spokes with exclusive Mega-G3 spoke pattern and anti-rotation system Quick release with eccentric-closure system Weight: 1360g Technologies: AC3: Under dry conditions the new technology increases braking performance 3% over the previous Bora while increasing the gap with its closest competitor by over 6%. However, when the conditions are insidious and rain has the competition worried, AC3 allows the Bora to excel. While the previous edition of the Bora offered results far beyond those found on competitors' wheels, the AC3 technology increases braking performance an astounding 43% over past Campagnolo models. The powerful braking of AC3 represents a nearly 55% performance gap over that of its closest competitor making for a rather significant advantage when the heat of the race is on.
