Tannus Armour Tubeless inserts are the result of years of top level multi-cell foam manufacturing mixed with extensive professional riding experience. At the heart of Tannus is the patented Aither Technology; a multi-cell foam compound that forms the structure of the Armour. The inserts are designed to displace small impacts while offering a spring-like rebound for a smooth yet playful ride. - 3% Faster than standard tubeless - Flexible sidewall stabilizing "Wings" for smoother ride quality, with 50% more vibration damping - 20mm of rim protection - Not a sealant sponge – keeps sealant where it belongs - Easy Installation (5 Minutes, No tools required) - 150g - About as much as a standard tube (a little lighter)

When top EWS Pro Riders ask you to develop a stiffer more durable fork axle, you listen. The stock 15mm axles and other lightweight aftermarket options were simply not tough enough for their race bikes. We don't quite ride at the pace of an EWS Pro, but we loved the simplicity and clean look of the axle so we made them available to buy. Axle F is 98% stronger and stiffer than a stock 15mm axle, yet still 20g lighter than a QR. We've replaced the QR lever with a simple 6mm hex. If you already carry the EDC multitool with you, there's no need for the heavy and bulky QR lever. FEATURES - 98% Stiffer and stronger than stock 15mm QR thru axle - 20g Lighter than stock QR thru axle - Low profile hex head won't get caught on trailside obstacles. COMPATIBILITY - For Fox and RockShox 15mm axle forks (Boost and Non Boost) - NOT compatible with RockShox RS-1 fork or Fox 36 Pinch Bolt Style (2016 and older) - NOT compatible with floating thru axles from 2021 Fox 36, 38 or 40 WEIGHT - RockShox Boost (15x110) 63g - RockShox Non Boost (15x100) 59g - Fox Boost (15x110) 61g - Fox Non Boost (15x100) 58g MATERIAL - 6061-T6 Aluminum

We loved the simplicity and clean look of Axle F so we made Axle R. Using a solid 7075-T6 rod rather than a hollow tube makes this the strongest possible rear axle design while still being lighter than a stock 12mm thru axle with integrated lever. If you already carry the EDC multitool with you, there's no need for the heavy integrated lever which can snag on trail-side obstacles. Add one of our coloured cap kits to match your Axle R to your bike. FEATURES - Lighter than stock 12mm thru axles with integrated lever or QR - 7075-T6 Solid rod design for maximum stiffness and strength - Low profile head won't get caught on trail-side obstacles. - 5mm and 6mm hex interfaces - All common axle length/thread combinations covered COMPATIBILITY - You need to know both your axle length and axle thread pitch to select your new OneUp axle. These are both specific to your frame. Hub spacing (e.g. 142x12) does not denote your axle size. Your axle length and pitch might be laser etched on your existing axle (e.g. 178 x 1.5). Check here first. If your axle size is not marked, check with your frame manufacturer. Axle specs are not usually listed on website specs. - Check our printable axle selector to ensure you pick the right length/thread pitch - NOT compatible with tapered "Syntace X-12" style axles

Zipp's 303 Firecrest Tubeless wheels are designed for the real world—a world of imperfect conditions, varying road surfaces, and elements where the bottom line is simple: efficiency = speed. They're 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, and 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. The 303 Firecrest Tubeless wheels are for dedicated cyclists who aspire to the latest in technology. They're for those who compete in races, against peers, or simply to conquer personal limits. - 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 - 40mm rim depth makes a light and aero wheel in every situation - Ships with 12mm end caps - Center Lock rotor interface (lockring included)

Zipp's 303 Firecrest Tubeless rim brake wheels offer all-around performance for a new era of road riding. They're rich in heritage yet loaded with innovations; as adept in the mountains as on rolling hills, windswept farm lanes, or ferocious field sprints. At Zipp, we never rest on laurels. These wheels feature a 19mm internal width and are tubeless ready. That means you can run lower tire pressure for greater cornering grip and compliance while still benefiting from reduced rolling resistance and without the risk of pinch flats. When it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. They're lightweight and feature ABLC Sawtooth Technology, a complex dimpling pattern first developed for our top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance. The ShowStopper textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. Lastly, at the center of the 303 Firecrest Tubeless rim-brake is a new versatile and durable hub, the German-engineered ZR1. - Tubeless for secure performance even when ridden at lower tire pressures - New ZR1 hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Versatile 45mm rim profile that's fast, stable, and versatile - ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel - Showstopper textured brake track delivers superior modulation and shortest stopping distances in wet and dry conditions - New Zipp graphics and cosmetic identity that scream speed - Ships with QR end caps, quick release skewers

Zipp's 303 Firecrest Tubular Disc-brake wheels offer game-changing innovations for performance-minded cyclists. These wheels were developed to meet the needs of our sponsored professional road and cyclocross racers as well as any cyclist who prefer the time-proven ride qualities of tubulars. The 303 Firecrest Tubular features our ABLC Sawtooth dimple design which extends all the way to the edge of the rim. The rim features construction upgrades that deliver improved impact resistance. These innovations enhance a wheelset that's excelled in two of pro cycling's harshest proving grounds, the Spring Classics and the Cyclocross World Cup. At the center of the 303 Firecrest Tubular is a versatile and durable new hubset, the German-engineered ZR1 DB. - Go-anywhere 45mm rim depth tubular pro proven in Spring Classics and Cyclocross World Cup - New ZR1 DB hubset is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Center Lock rotor interface (lockring included) - New Zipp graphics and cosmetic identity that scream speed - Ships with 12mm end caps
