intended use of the wheelset: Cross Country / Marathon
That the Italians created to Extralite small CNC art, is beautiful longer known. With the development of Hyperhubs they have outdone themselves. The hub body is extremely complex CNC-machined from high strength aluminum 7075TX. In the rear hub, a pulley freewheeling sitting with 36 teeth. All the intended use Italian brain lard resulted in extralight hub that can fold the technophile mountain bikers & jaw downwards.
Extralite Hyper JF
Weighing 85 grams, it is probably one of the lightest front hubs on the market which does not have to shy away from a race. Especially the oversize running hub flange of the disc side is a part of the weight of secrecy, it directly reduces the high loads, transfer the disc brakes on rims and spokes. Of course, for Extralite typical, run of the highest precision. This not only saves weight but also looks extremely good.
Extra Lites unique bearing adjustment system Micro Tuner, allows easy and externally adjust the bearing clearance. The precise adjustment of the hub bearings ensures low bearing friction and no play at the rim. On request, the bearing in a ceramic version.
Rarely lightness was so kombinert with low maintenance and durability.
Extralite Hyper JL for Lefty
Weighing 88 grams, it is probably one of the lightest on the market hub for Lefty forks.
Especially the oversize running hub flange of the disc side is a part of the weight of secrecy, it directly reduces the high loads, transfer the disc brakes on rims and spokes.
Compatible with all Lefty Lefty and hybrid, for Lefty 2.0 and Lefty SuperMax is an optional adapter for the brake mounting required.
Extralite Hyper JR
Weighing 185 g, it is probably one of the easiest rear hubs on the market which does not have to shy away from a race. Especially the oversize running hub flanges with the far distance are a part of the weight of secrecy, they directly reduce the high stress and worry with its stable base for an extremely rigid impeller, especially with 29ers.
Extra Lites unique bearing adjustment system Micro Tuner, allows easy and externally adjust the bearing clearance. The precise adjustment of the hub bearings ensures low bearing friction and no play at the rim. A toothed disc freewheel with 36 teeth absorbs extreme loads and provides fast response to the trails. Rarely lightness was so kombinert with low maintenance and durability.
The rims of Notubes are probably the most commonly installed when a spitzenklassiger wheelset is requested with lightweight aluminum rim. The rim profile is optimized such that this wheel takes out a proper stiffness from very little material. In addition, the rim Tubeless ready! This means that normal tires can be driven without tube. For this, the rim must only me provided Tubelesstape and the tires are mounted with some sealing milk. By omitting the tube the friction between tire and inner tube and the flexing of the tube is completely eliminated. As a result, the rolling resistance is reduced while simultaneously increasing comfort and grip!
NoTubes ZTR Crest MK3 With the MK3 Notubes brings a further development of their legendary Crest rim on the market. Despite a by 2 millimeters enlarged inner width Americans were able to save 20 grams of weight to the rim and at the same time increase the stiffness. Made possible by the inspired by the Valor carbon rims new rim design. With the increased size of 23 mm inner width of the tire increases in volume and is located at low air pressure stable on the rim. After Notubes Wide Right system the width of Crest MK3 has been optimized for 2.0 inch to 25.2 inch tires. For previous version remained the same over the years is the refined Bead Socket Technology and the superior characteristics Tubeless. An extra light rim, the tire can develop fully and the tire volume increases compared to a conventional rim. This leads to a lower rolling resistance and better damping characteristics.
intended use: Cross Country, Marathon
recommended weight limit incl Clothing: 75 Kg. (28/28 Hole) 85 Kg (32/32 Hole)
NoTubes Arch MK3 The ZTR Arch MK3 was developed with the input of the Enduro World Series teams. Despite an increase by 5 millimeters tremendous inner width compared to Arch EX, the Americans were even able to reduce the weight of the MK3 minimal and at the same time increase the stiffness. By enlarged to 26 millimeters inside width of the tire increases in volume and is located at low air pressure stable on the rim. After Notubes Wide Right system the width of the Arch has been optimized for MK3 2:25 inch to 2.5 inch tires. Compared to the ZTR Crest Arch EX heavier drivers provides more stiffness and reserves in borderline situations.
intended use: Cross Country Marathon
recommended weight limit including clothing. 95 Kg (32/32 Hole)
Sapim CX-Ray spokes are called spokes. The middle part is butted during production to 1.5 mm in diameter and forged flat in the last step. These processes ensure a strengthening of the structure and bring forth extremely durable spokes.
Wheel building at R2-Bike
Our wheels are assembled by our farmers impeller entirely by hand. While the entire structure is considered important that not only the concentricity true, but also that the spoke tension is as uniform as possible. The special care allows us to give a lifetime guarantee against spoke breakage as long as this was not caused by force!
Furthermore, you get to our impellers following services:
- A universal wheel bag for all standard sizes.
- An extra spoke nipples + to be able to repair the wheel shortly in all required spoke lengths even after accidents.
- A free initial inspection of the impeller, with the resulting work is completely free! There are only shipping.
- A Crash Replacement promise. If you have a wheel damage due to force majeure, we build your wheel on once again. We provide 100% discount on all labor costs and only charge the material!
