Wheelset 26 "Extralite Hyper Hubs with NoTubes Arch MK3 Rims Sapim CX Ray Spokes These hubs show which highly optimized designs are made possible using modern computer technology. Extralite develops the hubs by means of simulation programs and all kinds of expertise and thus always achieves new weight records. Thereby no losses in the stability and durability are taken! The industrial bearings used have sealing discs which are supported by an external dust cover and rubber seal. This double sealing system outperforms many, significantly heavy hubs in the market!
Extralite HyperHubs 2
In Extralite, the freewheel is realized by means of a toothed disc made of aluminum which engages directly into the gearing of the free-floating body. The integrated design of the mechanics also saves significant weight.
The HyperHubs 2 have an improved seal between the hub body and the freewheel, providing better sealing with low friction. In addition, the connection between toothed disc and hub body has been optimized. If this toothing is worn out, it is now possible to use a new toothed disc slightly offset and thus to double the service life.
NoTubes Arch MK3 The ZTR Arch MK3 was developed with the input of the Enduro World Series teams. In spite of a huge 5 millimeters enlarged inner area compared to Arch EX, the Americans could even reduce the weight of the MK3 to a minimum and at the same time increase the stiffness. This is made possible by the new rim construction inspired by the Notubes carbon rims. Due to the inner width, which is increased to 26 millimeters, the tire gains volume and sits more firmly on the rim at low air pressure. According to the Notubes Wide-Right system, the width of the Arch MK3 has been optimized for 2.25 inch to 2.5 inch tires. The Bead Socket Technology, which has been refined over the years, and its superior tubeless properties, has remained the same as the previous version. Thanks to an extra low rim flange, the tire can fully unfold and the tire volume increases compared to a conventional rim. This leads to a lower rolling resistance and better damping behavior.
Sapim CX-Ray spokes are so-called knife spokes. The middle section is confined to 1.5 mm diameter during production and flat forged in the last working step. These processes provide a solidification of the structure and produce extremely durable spokes.
Wheel construction at R2-Bike
Our impellers are assembled completely by hand from our impeller builders. During the whole construction, it is important that not only the concentricity is correct, but also that the storage voltage is as uniform as possible. The special care allows us to give a life-long guarantee against spike breakage, as long as this has not been caused by the influence!
Furthermore, you will get the following services:
- A universal impeller bag for all common sizes.
- A spare spoke + nipple in all required spoke lengths to repair the impeller at short notice even after accidents.
- A free first check of the impeller, during which resulting work is completely free! Only shipping costs are charged.
- A crash replacement promise. If your impeller is damaged due to force majeure, we rebuild your impeller once. We grant 100% discount on all labor costs and only charge the material!
