Wheelset 26 "Extralite Hyper Hubs Hubs with NoTubes Crest Rims and Sapim CX Ray Spokes These hubs show which highly optimized constructions are made possible by means of modern computer technology. Extralite develops the hubs by means of simulation programs and all sorts of expertise and thus constantly achieves new weight records. There are no losses in stability and durability! The industrial bearings used have sealing washers, which are supported by an external dust cap and rubber seal. This double sealing system exceeds in its effectiveness many, clearly heavy hubs on the market!
Extralite HyperHubs 2
The freewheel is realized by Extralite on a toothed pulley made of aluminum, which engages directly into the teeth of the freewheel body. The integrated construction of the mechanism also saves considerable weight.
The HyperHubs 2 have an improved seal between hub body and freewheel, which provides a better sealing effect with the same low friction. In addition, the connection between the toothed disc and the hub body has been optimized. If this gearing is worn, it is now possible to use a new toothed disc slightly offset and thus to double the service life.
NoTubes Crest MK3
With the MK3, Notubes brings an evolution of their legendary Crest rim on the market. Despite an increased inner width of 2 millimeters, the Americans were able to save 20 grams on the rim and at the same time increase their stiffness. This is made possible by the new rim design inspired by the Valor Carbon rims. Due to the increased inner width of 23 millimeters, the tire gains in volume and sits more stable on the rim at low air pressure. After the Notubes wide-right system, the width of the Crest MK3 has been optimized for 2.0 inch to 2.25 inch tires. The previous version has remained the same over the years refined Bead Socket Technology and the superior tubeless properties. With 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 a better damping behavior.
Sapim CX-Ray spokes are so-called knife spokes. The middle part is butted during production to 1.5 mm diameter and flat forged in the last step. These processes provide a solidification of the structure and produce extremely durable spokes.
Wheel construction at R2-Bike
Our wheels are completely assembled by hand by our wheel builders. Throughout the bodywork, it is important to ensure that not only is the concentricity correct, but also that the spoke tension is as even as possible. The special care allows us to give a lifetime warranty against spoke break, as long as it was not caused by violence!
Furthermore, you will receive the following services for our wheels:
- A universal impeller bag for all common sizes.
- A spare spoke + nipple in all required spoke lengths to be able to repair the impeller at short notice even after accidents.
- A free first inspection of the impeller, the 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!
