ZIPP 303 Firecrest 650b Tubeless Disc-Brake Front WheelThe definition of road cycling now includes gravel and dirt in addition to pavement. Simultaneously, bikes are evolving to meet the requirements of smaller riders. Zipp's 303 Firecrest 650b Tubeless Disc-Brake wheel was created to fulfil these needs. The smaller rim provides room within frames and forks for big-volume tyres, delivering improved comfort, compliance and cornering performance on the most challenging terrain. A 45mm rim profile reduces wind resistance, rolling resistance and weight but benefits from a wider internal width for enhanced performance and ride quality on almost every surface imaginable. ABLC (AERODYNAMIC BOUNDARY LAYER CONTROL)ABLC refers to the patented and instantly recognisable dimpled pattern found on all of Zipp's carbon rims. ABLC smooths airflow across the rim surface, and this latest third-gen iteration features up to four times more dimples than before.AEROBALANCEZipp wheels are race-ready before they are camera-ready. Using a combination of testing methods, Zipp refines aero performance to new levels of excellence. Aerobalance ensures the perfect balance of aero efficiency and crosswind stability.

Zipp’s 404 Firecrest Tubeless Disc-brake is the icon of speed with three decades of use.The 404’s heritage as Zipp’s icon of speed extends back decades, and its future is even brighter. At 58mm deep, the 404 Firecrest Tubeless is ideal for road races, time trial and triathlon, and gran fondos. The wheelset’s 23mm internal width is perfect for running wider tubeless tires at reduced air pressure. That is a vital component of Total System Efficiency, or TSE, an approach to speed on ever-changing roads and riding conditions. 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 tire 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 tires required 286 watts to maintain a speed of 40kph. That’s a 4-watt savings compared with the previous model 404 Firecrest. At the center of the 404 Firecrest Tubeless Disc-brake is a versatile and durable hubset, 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.

DT Swiss s benchmark setting AERO+ rim matched to a punchy mix of top end Aerolite and Aero Comp spokes, laced to premium Ratchet System hubs makes for a wheel that delivers in all riding situations.47mm deep carbon clincher tubeless ready rimSpokes: DT Aerolite and DT Aerocomp straight pull spokesHub type: 240 with SiNC ceramic bearingsOptimised for 25-28c tyresWeight: 706g (front), 832g (rear)Maximum recommended system weight: 120kgThe ERC 1400's rims were designed from scratch in conjunction with former F1 head of engineering JP Ballard and his team at the GST wind tunnel in Immenstaad, Germany. Using a bespoke fluid dynamic analysis system that for the first time allowed the designers to model and quantify the effect of crosswinds on a wheel's handling a rim profile was developed that gives an optimal balance between aerodynamics and handling. This is why the ERC 1400 rim is precisely 47 mm deep and 27 mm wide, any wider and you'd see an unacceptable increase in drag, any deeper and you'd compromise handling in rough conditions, we call this concept Aero+ and the result is a blindingly fast yet truly all conditions wheel.DT's renowned 240 hub internals are combined with a freshly optimised SPLINE hub-shell designed to improve spoke bracing and improve stiffness, an upgraded 36-tooth ratchet ensures lightning fast engagement. A carefully chosen blend of Aerolite and Aerocomp straight pull spokes offer a great blend of strength, speed and comfort. For those looking to use the latest tyre tech the ERC 1400's come tubeless ready but can also be used with standard clinchers. The front wheel comes ready for 12 x 100 mm thru axles, the rear comes ready for 12 x 142 mm thru axles. Includes tubeless rim tape and valves.

Zipp’s 303 Firecrest® Tubeless Disc-brake wheelset 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. Deeply 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 32mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. At the center of the 303 Firecrest Tubeless Disc brake is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless Disc-brake wheelset 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. Features: New Zipp graphics and cosmetic identity that scream speed Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile Lighter Weight than its predecessor, making it nimble and fast. Tubeless Made Easy, optimized tire bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tire. Ultra-wide 25mm rim profile creates a better tire interface to be fast on or off the road New 40mm rim depth makes a light and aero wheel in every situation New ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement Ships with 12mm front and rear end caps Center locking rotor interface.
