R2BIKE wheelset 29" XC DC | Hope MTB Center Lock hubs | Duke Carbon rims
Application: Cross Country XC, Down Country DC
With this wheelset, even racers can really let it rip. The indestructible Hope hubs and the superbly crafted Duke carbon rims are forgiving of the occasional riding error, while the well-balanced selection of components guarantees high reliability and a long service life.
Hubs
At the center of the wheelset are the Pro 5 hubs from the English cult manufacturer from Barnoldswick. The experience gained from 30 years of designing and manufacturing high-quality drive elements has been incorporated into their development with the aim of improving proven technology in order to meet the demands of current and future bicycle technology.
The design of the rear hub differs significantly from its predecessor, with an enlarged body that generates more rigidity without increasing the weight. This is noticeable above all in a much more direct ride. At the same time, the diameter of the spoke flange has been increased, making it easier to build very stable wheels.
The highlight of the rear wheel hub is the new 6-pawl freehub system in offset design, which is characterized by the fact that three of the six pawls are always engaged when riding in order to distribute the load evenly. In addition, the freehub gearing has been increased from 44 (Pro 4) to 54 teeth, resulting in a total of 108 engagement points and a low free travel of just 3.33°. In addition, some material has been removed from the pawl springs, which slightly reduces the spring force and lowers their resistance. Hope has thus achieved the right balance between smooth running and durability with the Pro 5.
The hub can withstand negative external influences for a long time, thanks to the high-quality anodization and the very well-sealed stainless steel industrial bearings. Should the ravages of time take their toll on the hub, it can be dismantled and serviced with little effort. It can also be easily converted to a different hub standard.
Rims
With the Lucky Jack SLS5, the Duke becomes a king. The French have once again succeeded in significantly improving their cross-country rim compared to the previous version. In doing so, they have once again pushed the seemingly technically possible boundaries.
But how did they do it this time? The use of the highest quality carbon fibers was a matter of course from the outset. Clever use of materials means that only as much is used as is actually needed. In contrast to the Ultra version, particularly vulnerable areas, such as the rim flange or base, were reinforced. No compromises were made in the choice of resin either. This has proven itself in aerospace technology, reduces weight and at the same time increases impact resistance. As a result, there is no need for reworking or painting after production. A new feature of the SLS5 production process is the integrated DRC (Dynamic Response Comfort) technology, which guarantees controlled deformation of the rim off-road and allows the stored energy to be used for explosive acceleration out of corners. It also improves control of your bike and significantly increases comfort.
Despite all the optimization, durability must not fall by the wayside. Duke presses so-called ImpactGuard's, highly elastic energy-absorbing inserts, into the cavities on both sides of the rim, which can absorb mechanical impacts and thus contribute significantly to stability.
The new shape, with the small hump on the inside of the rim, also absorbs high load peaks better without increasing the weight. In addition, the preformed spoke holes, the spoke cores, ensure a continuous structure of the carbon fibers. This means that subsequent drilling of these holes is not necessary.
The rims of the SLS5 series also have an asymmetrical rim profile, which enables a more even spoke angle. This optimization of the spoke angle has a number of advantages. The tension on both sides can be better aligned, which is beneficial to the durability of the spokes and the wheel as a whole. The normally direction-dependent lateral stiffness is also adjusted, making the wheel more stable.
Please note the maximum permissible system weight in the rim selection menu under "Show description".
Wheel construction at R2-Bike
Our wheels are assembled entirely by hand by our wheel builders. During the entire assembly process, great importance is attached to ensuring that not only the concentricity is correct, but also that the spoke tension is as even as possible. This special care allows us to give the first owner a lifetime guarantee against spoke breakage, as long as it was not caused by force.
The following services are also included for first-time buyers:
You get a universal wheel bag for all common sizes included.
You will receive a spare spoke with nipple in all required spoke lengths so that you can repair the wheel quickly after an accident.
Within 2 years of purchase, you will receive a free initial inspection of the wheel, during which the resulting work is completely free of charge. Only shipping costs are incurred.
You get a crash replacement promise: If your wheel is damaged within 2 years of purchase due to force majeure, we will rebuild it once. We grant a 100% discount on all labor costs and only charge for the material.
