Fast Forward Ryot 55 DT240 Carbon Road Disc WheelsetFeaturing a full carbon clincher rim construction, this race-ready road bike wheelset delivers fantastic strength and stiffness as well as an impressively low weight. Fast Forward has also kitted it out with some of its finest technologies including a Law Tech aero profile that delivers superior speed, aerodynamics and wind-tunnel-proven performance. Another highlight is its tubeless ready technology, which allows riders to enjoy tubeless benefits such as lower rolling resistance, greater comfort and fewer chances of flats or punctures. Coming complete with Centrelock disc brake compatibility, it's a great choice of upgrade for riders who want the ultimate speed weapon for tackling all the demands associated with road racing and competing.Full Carbon Clincher Wheelset with LAW Tech Aero ProfileSetting the goal to bring the fastest wheel out there Fast Forward developed an updated rim profile called LAW Tech. LAW is short for 'Laminar Airflow Wing' and has been specially developed to deliver better aerodynamics when using wider tyres by creating a smooth airflow. With the LAW tech rim, profile the RYOT55 brings an aerodynamic advantage of 5 watts from 25mm tyre widths as where its predecessor, the F6 with DARC technology, was best suitable with 23mm tyres. When compared to its competition, Fast Forward's wind tunnel tests showed an average advantage between 1,5 and 2,7 watts. Taking the RYOT55 out on the road these watt savings translate into the same result while you save some energy, or you can go faster when putting in the same energy as before. This will make the difference when you're in the final of a race or need to outsprint your cycling buddies. Lightweight with DT Swiss 240 HubsBeing competitive in aerodynamics is one thing, weight is also very important. With 1620 grams for the RYOT55, Fast Forward built a wheelset that is there to last and offer outstanding performance in stiffness due to the partial use of DT AeroComp spokes. The 21mm internal rim width will also result in an effective tyre width of 28,2mm when using 25mm tyres. The RYOT55 is built around the updated DT Swiss 240 hubs which have an improved EXP ratchet system. The hub internals now offer an even higher precision with fast engagement and increased stiffness combined with a lower weight. This helps to bring the performance of the wheel to an even higher level. Built for you with the most precision and same amount of attention Fast Forward spends on all wheels at its facility in The Netherlands. The wheels are shipped as a complete package with accessories in a nice protective wheel bag. (disc rotors not included).

The chainset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. This Compact version features a 50/34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.
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.
