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.

Zipp 404 Firecrest Carbon Tubeless Rear WheelZipp's legendary speed weapon, the 404 Firecrest, is better than ever. This go-to rim-brake rear wheel is, for the first time, tubeless ready. That means you can run reduced tyre pressure for reduced rolling resistance and increased cornering grip and compliance without the risk of pinch flats. This rear wheel's 58mm rim depth is a classic that has carried athletes to victory in every kind of event and situation - every triathlon distance, breakaways, field sprints and hilly finishes. Zipp's ABLC Sawtooth Technology uses a complex dimpling pattern to improve aero efficiency. Zipp's ShowStopper textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the centre of the 404 Firecrest Tubeless rim-brake is a versatile and durable hub, the German-engineered ZR1. If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless is a savvy and speedy choice.ABLC SawtoothThe Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim's profile to further reduce high yaw drag and improve crosswind stability. ABLC Sawtooth dimple design helps manage air flow around the rim and contributes to creating a faster, more stable wheel.Features: Rim Material: Carbon with UD Fibre finish and adhesive decals Use: Road Axle Type: QR 135mm (quick release) Internal Rim Width: 19mm Rim Depth: 58mm Rim Profile: Symmetrical Brake Compatibility: Rim Brake Size: 700c Tyre Compatibility: Clincher, Tubeless Ready Surface Texture: ABLC SawTooth Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 24 Spoke Pattern: 2 Cross Driver Body Type: SRAM XDR Axle Material: Aluminium Bearings: Cartridge - Steel Driver Mechanism: 6 Pawls Leaf Spring Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheelTechnologies: New Zipp graphics and cosmetic identity that scream speed.

AM 808 Firecrest Carbon Tubeless Disc Brake Center Locking 700c Rear 20Spokes Standard Graphic B1808 Firecrest Tubeless Disc BrakeZipp’s 808 FirecrestTubeless Disc-wheelset is all about science to achieve speed. That’s the perfect approach for Zipp’s stiff deep-rim choice for triathlons, criteriums and road racing. At 80mm deep, its rim is designed to make you faster in every way. Zipp’s Total System Efficiency design approach, or TSE, infuses the 808 Firecrest with new features, including a huge drop in weight from its previous iteration, well more than 280 grams. Also, the wheel is designed with a hookless and tubeless rim profile and 23mm internal width. That’s ideal for running wider tires at lower pressure for reduced rolling resistance and greater cornering grip. In fact, TSE attacks the four primary barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Losses. Zipp’s legendary Firecrest rim shape provides high aero efficiency and crosswind stability. Also, Zipp’s ABLC Technology uses a complex dimpling pattern to improve aero efficiency. What’s more, while this wheelset is optimized for tubeless tires, you still have the option to run Tubeless or tubeless ready tires with tubes. The 808 Firecrest with TSE builds on this wheel’s legacy as a go-to wheel fastest or optimized for TT, tri and crit racing. This wheelset is fastest with a 28mm tire. Disc brakes also offer more reliable speed modulation and braking power in all weather conditions.

Zipp’s 808 Firecrest® Carbon Clincher is pure engineering science. It has to be. To achieve speed with an 82mm rim depth is one thing, but to be fast but also high crosswind stability, well, that requires serious attention to detail. Yet that’s just what the 808 Firecrest Carbon Clincher accomplishes – speed with stability, what we call AeroBalance™ – which has made it a longtime favorite of triathletes, time trial specialists, as well as any cyclist in search of free speed. At Zipp, that search for aero efficiency is unrelenting. To that end, the latest iteration of the 808 Firecrest Carbon Clincher provides more speed, better control, and greater stopping power than its predecessor: More Speed: Revised rim profile for reduced aerodynamic drag developed by our advanced development team in Indianapolis, Indiana, USA. Greater AeroBalance™: ABLC™ Sawtooth™ Technology, a complex dimpling pattern first developed for our top-level NSW wheel lineup. This technology helps reduce high yaw drag while improving crosswind stability. This helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance. Better braking: Zipp’s ShowStopper™ textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. Lighter Weight: The 808 Firecrest Carbon Clincher is 55 grams lighter than its previous iteration.
