Zipp 404 Firecrest Carbon Tubeless Rear Wheel - Black - Shimano/SRAM}, Black
  • £1188.99

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.

ENVE Foundation AG25 Tubeless Clincher Disc Gravel Wheelset - 700c - SRAM XDR
  • £1194.99
  • RRP £2100.00
  • Saving you £43

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 Disc Brake Wheelset - Shimano/SRAM
  • £1399.00
  • RRP £1600.00
  • Saving you £13

First launched in 2011, Zipp’s 404 Firecrest wheelsets are not only firmly established as one of the fastest wheels on the market, but also they have arguably helped shape the entire category of modern aerodynamic wheels. This iteration, to use the company’s term, is no less than a ‘Speed Weapon’; a ‘weapon’ that boasts a 58mm-deep rim and weighs less than ever at 1470g. It is now cheaper than before, making this a product that’s virtually a no brainer. Whether you’re looking for a wheelset fit for a Spring Classic, time trial, triathlon, or simply to compete against your mates on the weekend club run, this is an option which is hard to look past. Single Purpose: Speed Whereas the 303 Firecrest is Zipp’s premium all-rounder, which’ll happily serve its rider on or off road, the 404 is all about going fast. Somewhat unusually, the company aren’t claiming to have made a more aerodynamic rim, quite the opposite. As the rim is wider, the shape is actually less aerodynamic than the previous version. However, a multitude of other enhancements — what has been termed Total System Efficiency (TSE) — has enabled the developers to produce a faster-overall wheelset. In addition to examining how wind resistance affects the wheels, the effect of gravity, rolling resistance, and vibration losses have also been tested. Notably, the internal width of the rim is now wider at 23mm, and has been optimised for a tyre of 25–28mm — depending on rider size. This allows the tyre to be ran at a lower pressure and in turn means it can roll more smoothly over imperfect road surfaces, increasing efficiency and making for a faster wheel overall. The weight of the wheelset has also been reduced, increasing its speed and lessening the impact of gravity when going up-hill. All this adds up to a wheel that is faster on varied terrain and ever-changing riding conditions. Going Hookless Hookless rims are slowly becoming the de-facto choice for wheel makers, at least in the high-end wheel space. What this means is, instead of the traditional ‘hook’ on the inside of the rim, the wall is straight. This comes with a number of manufacturer-claimed benefits. For one, with a hookless rim, the transition between the tyre and rim is less abrupt, which helps to cut a cleaner shape through the air. As well as the performance benefits, hookless rims are also cheaper, easier, and more environmentally friendly to produce, all of which amounts to cost savings for the buyer. The Hub Spinning the wheelset is an all-new, German-engineered, versatile and durable hubset. Using a six-pawl freehub, with 66-point engagement, the hub has a pick-up angle of 5.45 degrees so that when you put the power down, it’s translated to forward motion almost instantly. Overall, if you are looking for just one wheelset for road riding, be that for racing or simply for fun, then the 404 Firecrest is a difficult option to look past.
