Zipp s 303 Firecrest Tubeless Disc-brake wheel is designed for the real world a world of imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It s faster, lighter, and more capable over varied terrain, whether the surface is pavement in all its conditions or no pavement at all. New Zipp graphics and cosmetic identity that scream speedVersatile endurance wheel for the modern road bike with tubeless and hookless rim profileLighter Weight than its predecessor, making it nimble and fast.Tubeless Made Easy, optimised tyre bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tyre.Ultra-wide 25mm rim profile creates a better tyre interface to be fast on or off the roadNew 40mm rim depth makes a light and aero wheel in every situationNew ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagementShips with 12mm front and rear end capsCentre locking rotor interface. Lock ring is included with the wheelsXDR or SRAM/Shimano driver bodiesCampagnolo driver body sold separatelyDeeply rooted in Zipp s drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced: Wind resistance, rolling resistance, rider fatigue, weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tyre, boosting aero efficiency on the road. The wide rim stance also features less tyre deflection for reduced rolling resistance. The combination of the wider tyre, increased tyre volume, and lower tyre pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions the tyre and wheel system absorbs the shaking, not the rider. At the centre of the 303 Firecrest Tubeless Disc brake is a versatile and durable new hub, the German-engineered ZR1 DB. This hub features 66 points of engagement for quicker response. The 303 Firecrest Tubeless Disc-brake wheel is for dedicated cyclists who aspire to the latest in technology. Its competitors in races, against peers, or simply conquering personal limits. This is about becoming faster and matching your motivation to the most advanced technology.Orientation (wheels): RearSize (wheels): 700cRim construction: CarbonTire compatibility: Clincher Tubeless ReadyRim depth: 40mmSurface texture: ABLC SawToothBrake compatibility: Disc (Center Lock)Rim - inside width: 25mmRim profile: SymmetricalRim finish: UD fiber, adhesive decalsColor (Decal): StandardNipple material: AluminumNipple anti-rotation: Sapim Secure-LocSpoke type: CX-SprintSpoke count: 24Spoke pattern: 2 CrossHub: ZR1 Disc BrakeDriver body type: SRAM/Shimano Road or SRAM XDRColor (hub): BlackAxle type (Wheels): TA 12x142Axle material: Aluminum front & rearBearings: Cartridge - Stainless SteelDriver Mechanism: 6 Pawls Leaf SpringDriver body material: AluminumMax tire pressure: 73psiMax recommended rider weight: 250lbsPart Weight (g): 739Please Note: The below tyre brands have communicated to us that their tubeless models are compatible with our tubeless hookless straight side wheels.

The Shimano RS710 C32 disc-brake wheelset, along with the deeper-section C46, is the Japanese brand’s most affordable carbon, road wheelset ever. Drawing on their experience in producing the more premium Dura-Ace and Ultegra lines, Shimano have crafted a wheelset that balances aerodynamic advantage, with weight and overall rigidity. A Wheelset for Mountains Weighing a respectable 1,511g for the set, the Shimano RS710 C32 is perfect for those big days spent cycling in the mountains. Although there might be lighter wheels on the market—though perhaps not this price point—you certainly won’t feel weighed down by these hoops. With a lighter wheel you’ll feel the zip when you put down the power, getting you up to speed in no time. Whether you need a quick burst of acceleration to crest a sharp hill or to see off a potentially race-losing attack, the RS710 C32s won’t leave you watching the peloton motor on without you. Wider Rims, Better Braking Boasting a wider rim profile than any other Shimano wheel at this level, you’ll be able to fit a wider and tubeless tyre; the benefit of this being you can run the tyre at a lower pressure. It’s widely accepted now that, contrary to past beliefs, running a wider tyre at lower pressure reduces rolling resistance, which in turn increases speed for a given power. Furthermore, a wider tyre will work more effectively with a wider rim in terms of aerodynamic performance, again offering you more speed for less effort. The Shimano RS710 C32 is engineered for hydraulic disc-brakes, meaning you’ll benefit from the stopping power offered by this braking system. The advantages of discs over rim brakes have now been widely accepted: you’ll have consistent performance in the wet, you won’t have to fear overheating your rims on long and/or steep descents, and you won’t be concerned about your expensive rims eroding away every time you break. Lastly, for the mechanically minded, Shimano have stuck with their tried-and-tested cup-and-cone bearings in the hubs. This is similar to the used on many of the brand’s hubs, which are highly regarded for their reliability and simplicity. So if it’s a carbon wheelset that’s relatively light, reliable, and offers top performance look no further than the Shimano RS710 C32. Product Features 32mm rim depth Compatible with 11- and 12-speed Weight: 1,511g for the pair Internal-rim width of 21mm External-rim width of 28mm Spoke count: 24 front and rear Hub design: cup and cone

Specifically, TSE focuses on overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. Zipp s ABLC Sawtooth Technology uses an intricate dimpling pattern to improve aero efficiency. Zipp s use of hookless (straight side) rims in the 404 Firecrest is integral to making you faster. With hookless, the transition between the tyre and the rim is more seamless and aero. Zipp s hookless rims have more efficient resin distribution, which means lighter, stronger wheels. Outdoor testing commissioned by Zipp revealed the real-world gains of Zipp TSE. A bike and rider system weighing 85kg (187lbs) on the new 404 Firecrest with 25mm tyres required 286 watts to maintain a speed of 40kph. That s a 4-watt savings compared with the previous model 404 Firecrest. At the centre of the 404 Firecrest Tubeless Disc-brake is a versatile and durable hub set, the German engineered ZR1 DB. If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless Disc brake is a savvy and speedy choice.

Shimano Dura-Ace R9270 C36 Carbon CL Disc WheelThe Dura-Ace R9270 C36 Carbon CL Disc Wheel from Shimano is a Tubeless Ready mid-depth-profile wheel that's versatile for steep climbs, fast sprints and long days in the saddle. It features a 36mm-profile full-carbon rim and a Centre Lock disc rotor mount while being compatible with 12mm E-Thru axles, this race-ready wheel is fast, aerodynamic and stable for road racing anywhere.With stunning acceleration, the new Dura-Ace R9270 C36 wheelset will change the way you experience climbs, corners, even stoplights. This is because it isn't just how much a wheel weighs but where the weight is on the wheel that matters. The all-new C36 design shaves mass at every opportunity but especially at the rim. The result is a lively wheelset that can transform your ride. Lighter, Wider and Faster Carbon Road Race WheelWith both a lighter, wider all-carbon rim and a lighter hub, the new Dura-Ace C36 won't shy away from a day of climbing. The new rim is 36 mm deep and still delivers good aerodynamic efficiency despite its gossamer weight. Meanwhile, the hub features an alloy freehub body and a new engagement mechanism for increased rigidity. Centre-Lock Disc Rotor MountThe Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency. D2 Aerodynamic Rim ProfileAerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tire bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road. Rear Wheel OPTBAL Spoke SystemThe OPTBAL rear wheel spoke system features 21 spokes—14 on the drive side and 7 on the non-drive side. Cassette spacing in today's wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally, high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel. Shimano E-Thru Axle SystemThe tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.
