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.

Any offering from Zipp is certain to come with high expectations, and this version of the Zipp 303 S wheelset doesn’t disappoint. With this edition, the wheel building pioneers are touting not only the speed and low weight of their wheels, but also the durability and ability to fit wide tyres, making them suitable for on and off-road exploring. All this at the brand’s lowest price point ever means this is a product offering value for money, as well as high performance. This listing is for a complete wheelset, you can also buy the front and rear wheel separately. Lighter, Stronger, Faster The Zipp 303 S wheelset is intended to be versatile, equally suited to training and racing in a range of conditions. Whether you’re on the silky-smooth tarmac of Majorca, the bone-shaking pavé of Flanders, or the dusty plains of Kansas, these wheels cover them all. Boasting a 45mm-deep rim, coupled with a respectable total weight of 1530 grams, these wheels offer a great balance between aerodynamics and weight, ensuring you have the speed on the flats and the low weight needed for when the road tilts up. As a wheel intended for racing, this product is expectedly stiff, and you’d be hard pressed to notice any lateral flex under those big, decisive accelerations. Additionally, even the most weight conscious can rest assured they won’t be held back on the climbs and that they’re responsive enough for sprint finishes on the road — whether that finish line is a sanctioned road race or the café, it doesn’t matter! Bigger, Wider, Faster Known as pioneers in the wheel-building space, Zipp are on trend in terms of offering wider tyre options. With wider tyres you can run lower air pressures, which can increase comfort and grip in the corners; importantly, this amounts to more speed, particularly across rough terrain. Boasting a broader, hookless rim, the Zipp 303 S wheelset is optimised for a 28mm tyre on the road but will happily take up to 50mm tyres for gravel adventures. Stopping Power It has become almost the norm for wheels to come in disc-brake-only versions, and that’s exactly what you get here. Being equipped with disc brakes means that when you squeeze the brakes — regardless of the conditions — you can be confident you’ll get consistent stopping power. Lifelong Quality Filled with the highest-quality steel bearings, the hubs will run smooth and should stand the test of time. So confident in the durability of the 303 S wheelset, Zipp are offering a lifetime warranty. Product Features Carbon-fibre rims 45mm-rim depth 23mm-internal rim width 27mm-external rim width Optimised for 28mm tyres, but accommodates up to 50mm Hookless rim Only compatible with tubeless tyres Disc brake (centre-lock) compatible 76 / 176 DB hubs with Center locking interface XDR driver body option Through axles — 12x100mm front and 12x142mm rear Sapim CX-Sprint J bend spokes. 24 front and rear.

The ENVE Foundation AG25 Gravel Wheelset is designed for everything from bike packing to gravel racing. “AG” stands for “Adventure Gravel” and this is the guiding principle behind the AG25. Part of ENVE’s new Foundation collection, the AG25 brings ENVE’s core technologies and trickle-down features from the ENVE G Series to riders seeking out adventure and ultimately looking to ride for the fun of it. The AG25 is a 700c gravel wheel that can take tyres up to 50mm, responding perfectly to the larger clearances of modern gravel and adventure bikes. The rim shape was developed by ENVE that would smooth out the ride while still delivering a confidence-inspiring feel when it comes to handling. The AG25 uses ENVE’s Wide Hookless Bead to minimise the chance of pinch flats. The wider leading edge of the rim disperses any impact from debris or potholes over a wider area. This leads to a 60+% improvement in pinch flat resistance as well as a 30+% improvement in impact strength. Drilled spoke and valve holes mean the carbon fibres in the AG25 run through the wheel uninterrupted as opposed to being cut. This makes for a stronger, lighter rim structure. Another benefit is that ENVE can control the shape of the rim at the spoke/nipple interface with greater precision. ENVE rims feature a conical nipple seat that prevents premature spoke fatigue while also ensuring wheel-build reliability. The AG25 uses the ENVE Foundation Road Hub, which uses ENVE’s core hub technologies. The hub shell uses simplified machining without compromising flange geometry and wheel build stiffness. The drive mechanism uses Instant Drive 360 technology and a 40t ratchet to deliver responsive engagement, minimal drag, and low maintenance performance. The bearings are premium full contact sealed NTN steel bearings. The Rotor attachment is center lock. The AG25 is also available with the Industry 1/1 hub. The ENVE Foundation AG25 Gravel Wheelset comes with ENVE's leading Factory Limited Warranty and Incidental Damage Protection. The Factory Limited Warranty protects buyers for five years from defects in material and workmanship, while the Incidental Damage Protection gives protection from damage caused to their wheels while riding, crashing or transporting bikes. Beyond these three years, there is a prorated discount structure available.

The all new TR 309/289 XC wheelset is designed to push the limits of aggressive XC/Trail racing and riding. Thanks to a new low profile and wide channel rim riders will notice increased cornering speed, direct power transfer and improved compliance. The Reynolds TR MTN hubs provide 10° of engagement for quick power delivery. The TSS/PRR3 rim construction delivers industry leading impact resistance and durability with a lifetime warranty. The 309/289 XC features a 30mm internal width front rim paired to a 28mm internal width rear. Wider rims allow you to run lower pressure, increase traction and add precision to your steering. Reducing the rims profile to 21mm for improved overall compliance and comfort. With most of the rider weight and power on the bike being transferred to the rear, a 28mm wide rim paired to 28 spokes creates an ideal balance between strength, comfort and performance. On the front, the rim has been widened to 30mm to add even more steering precision and sidewall stiffness where it matters most. To maintain a similar feel to the rear, the spoke count has been decreased to 24 to add compliance and reduce weight for a more flickable feel while navigating the tight and twisty sections of the trail. PR3 used in Reynolds Allroads, TR S and TR mountain wheels takes this same approach balancing structural requirements with performance and value.
