R2BIKE wheelset 29" XC DC | Tune MTB 6-hole hubs | Duke Carbon rims
Application: Cross Country XC, Down Country DC
With this wheelset, even racers can really let it rip. The indestructible Tune hubs and the superbly crafted Duke rims are forgiving of the occasional riding error, while the well-balanced selection of components guarantees a high level of reliability and a long service life.
Hubs
The Micro hub set is the ideal introduction to the world of lightweight MTB hubs from Tune. As you would expect from Tune, the new Micro Boost hubs are CNC-milled from 7075 aluminum. The special feature of the front hub is a new hub flange that does not require a carbon ring. The symmetrical design ensures optimum balance of the front wheel. The POEtry138 freehub mechanism keeps play to a minimum when starting off, so that direct power transmission is possible. The J-bend flanges make the hubs particularly stable yet lightweight.
Like all Tune hubs, the Micro Boost is produced, milled and assembled entirely in the Black Forest.
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 when selecting the 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 design, 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 due to force majeure within 2 years of purchase, we will rebuild it once. We grant a 100% discount on all labor costs and only charge for the material.
