USPS Shipping is $5.95 wrote the copy for a completely built rear wheel with the DT Swiss 460 32 spoke wheel and the 32 Spoke Quick Release 130mm Onyx Vesper Hub. It should give you some good information on the technology behind the Onyx Vesper Hub and the key reasons why you want to build a road or gravel bike wheel using this remarkable Wheel Hub: What it Is: This is a ground up custom road bike wheel featuring the famed Onyx Vesper Hub (Road Bike Version) built with a DT Swiss 460 Wheel with 32 Sapim Spokes. You can use Shimano 10 and 11 speed HG Hyperglide speed cassettes on this hub. Why This Wheel Was Built I wanted a wheel that was faster than any available off-the shelf high end road bike wheel. I had ridden Road Bike Wheels with the DT Swiss, White Industries,Chris King, ZIPP NSWs and a plethora of other high end road bike wheels with high end hubs. Constant obsessive research on the internet consistently pointed me to the Onyx Vesper, once i jumped into the rabbit hole of finding the fastest road bike hubs available to average road bike riders. My goal was pure and ridiculously simple. i wanted to ride the fastest spinning road bike wheels available but not break the bank and keeping the budget reasonable and under $1,000.00. Why Was The Onyx Vesper Hub Chosen Over The Rest? The Onyx Vesper, in its current second generation/iteration is a uniquely designed hub that incorporates the design of a tried and proven Sprag Clutch which is employed in vehicles and in aviation. The most prominent application of the Sprag clutch is in helicopters where maximal rotational speed of the primary rotor is required when the engine fails and obtaining a soft landing is crucial to avoid a hard helicopter landing. The Sprag clutch allows the helicopter rotor to spin with minimal friction thereby allowing maximum velocity of the helicoptor rotor when it spins without the motor being engaged. The minimization of friction also applies when designing and building mountain and road bike hubs. The Onyx Vesper hubs are eerily noiseless as this is a characteristic of the friction-less spinning of the hub internals. They were able to design the hub in this manner to allow the bike wheel to spin with much less friction than other hubs on the market while still maintaining strength, durability and reliability in being able to handle the torque of a demanding mountain bike ride or a road bike sprint. Why buying this wheel will make you faster on the road bike and will be one of the most cost effective performance upgrades you will make to your Road Bike? The proof is in the pudding...So they say. When riding with my weekly group ride friends, they will swear up and down that you have an electric bike motor assist thing going on with your new Onyx Vesper DT Swiss Wheel. The group ride averages about 25-30 miles of varied road topography with lots of rolling hills with moderate ascents thrown in to mix it up and to keep everyone honest. While other riders are furiously pedaling to maintain speed on the straights and rolling hills, you will be coasting and in some cases passing them as the rolling resistance and pedaling effort is reduced. In effect, you're coasting while everyone else is pedaling as you are saving energy and watts with your Onyx Vesper wheel. The folks at Onyx really built a hub that is a real game changer for all cyclists. I can honestly say that these are the fastest road bike wheels I have ever ridden. They were used in my 14 pound Trek Emonda RSL carbon fiber road bike. Here's a YouTube video of actual spin test of this wheel: https://youtu.be/se4we2sMSgI?si=Gsal46xn4THzvWgo A Detailed Technical Explanation of the Sprag Clutch is here: https://en.wikipedia.org/wiki/Sprag_clutch What is your background and motivation for building this custom road bike wheel? I am an avid cyclist with over 10 years of road bike experience. I have worked for 2 local bike shops and an Electric Bike manufacturer. What are you waiting for? Now's the time to spend the money on an upgrade that really makes sense and will help you go faster and save a bunch of watts in the process. Sprag Clutch Onyx Racing Products uses sprag clutches in its rear bike hubs. Sprag clutches are unique because they engage instantly but operate silently. In addition, all sprag elements maintain gentle contact with the driver and hub body, gliding with minimal friction until torque is applied. Their unusual shape allows freewheeling in only one direction. When a rider pedals to induce torque, the sprags rock slightly to wedge between the hub and driver, giving Onyx hubs infinite points of engagement, always ready to go when you are. Since there are no teeth or spring-engaged pawls like those found in conventional ratchet mechanisms, Onyx hubs are almost noiseless during freewheeling. Modular Freehub Unit (MFU) The MFU design is standard on the Onyx Vesper hub line and Classic hub series. Rather than sharing the drive and axle loads in our freehub system, the drive and axle loads work independently. Two oversized bearings in the hub shell support the driver, which also actuates the sprag clutch engagement system. The freehub body interfaces with the driver but spins on a separate set of bearings. This design generates longer bearing life in the freehub and stiffens the rear axle assembly. MFU also makes adopting current and potential Freehub body standards easier for Onyx without replacing the clutch or driver assemblies. Hyperglide Alloy Freehub Onyx Hyperglide alloy freehub bodies are not like the rest. They feature steel inserts to combat gouging while saving weight over a steel freehub. The freehub itself is machined from 7075 aluminum alloy and utilizes steel pins to reinforce seven of the splines. This patented design enables cassette alignment using the two key slots and replaceable wear faces on the remaining slots. When worn out, the steel pins are replaceable by hand or with a set of pliers. Ceramic Hybrid Bearings are standard on Onyx BMX Race hubs and Classic Hubs. Specially formulated for Onyx Racing Products bicycle hubs, these bearings feature ceramic (Si3N4) ball bearings and a hardened chrome steel race. Each bearing contains a heavy dual-lip seal for the outboard facing side and a lighter seal on the inboard side. A synthetic grease blend fill keeps these bearings spinning free and fast! Perfect for racing applications where every watt counts. Serviceable for long life. Floating Axle All Onyx rear hubs utilize a floating axle. This design separates drive forces from axle load under normal riding conditions. This approach further reduces drag when freewheeling and extends the bearing life of freehub bodies.
