This wheel fools you. The Lightweight Rundkurs Tubular Wheel is not their Meilenstein with track nuts. It's a track-specific wheel, designed for the forces of a banked velodrome.
 
It's similar in build to the older Meilensteins. 53mm deep rim with twenty front and rear spokes. Winds are different on the track and so are accelerations. The wind is mostly generated by riding fast and the accelerations are smoother, often taking place at higher rpms.
 
The biggest benefit is how Lightweight's great lateral rigidity comes at no cost of weight. Track wheels are often heavier to better resist the forces riders put on them, but with the high, uniform tension of Lightweights, no weight is added. You get a 555g front and 620g rear. When you consider that many front wheels are 800g and rears over 1,000g, these are feathery and make accelerations snappier.
 
The wheels come with traditional axle nuts. The rear hub is one-sided. The set comes with a double wheel bag.
 
Lightweight strongly urges buyers to register their wheels on the Lightweight website within five days of receiving wheels. Each wheel has a unique ten-digit number that is encoded on a microchip embedded in each wheel. This helps you with both their crash replacement program and Wheelprotection program-and can come in handy if your wheels are lost or stolen. The first applies to all wheels and entitles you to 30% off a replacement wheel if you destroy one in a crash. The second is their insurance program, which means that by paying up front, your Lightweight wheels are protected for three years from any damage that might occur. 
Lightweight Rundkurs Tubular Wheels put high performance track gear on a diet.
