intended use of the wheelset: Trail / All Mountain
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.
BOR AMD 444
The AMD 444 rim completes the range with BOR a lightweight All Mountain / Trail rim. It relies on old virtues, as the asymmetry and simply exported stainless steel loops, which provide better force against the nipple seat.
Is extended this concept to a grown to 24.7 mm inner width that can better stand on the rim of the tire. The carcass sits characterized wider and thus substantially straight on the rim, which also increases the volume of air. A premature buckling of the tire is prevented. You can go so with less air pressure, what the grip level increased significantly without having the feeling that the tire on the rim drumming.
By Asymmetric profile an almost identical spoke tension on the left and the right permits and prevents bending of the spoke nipples, providing ultimately a stable and durable wheel.
Of course, the rim can be driven with a matching tubeless kit and corresponding tire without a tube.
recommended weight limit including clothing. 90 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!
