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.
DUKE Lucky Jack Carbon
The Lucky Jack by DUKE is a very light and broad rim for cross country and marathon use.
Weighing 330g the weight is surprisingly low. Great value have the dimensions of the rim. With 31 mm outside and 24.8 mm inside the rim provides not only an excellent lateral stiffness, but also the tire optimum support width. Also at low air pressure, the driver (in) no spongy driving feel, as the tires can snap off bad side. Grip and comfort of the tire increase remarkably! Of course, the rim can be driven with sealing Tubeless milk.
The rims are veresehen with an asymmetrical rim profile, which requires a more uniform pitch angle of the spokes. This optimization of the spoke angle brings a number of advantages. The spoke tension on both sides can be better matched to one another, what is the shelf life of the spokes and the entire impeller conducive. The normally directional lateral stiffness is also adjusted so that the wheel appear rigid in itself.intended use: Cross Country, Marathon
recommended weight limit including clothing. 85 Kg (28/28 Hole) 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!
