intended use of the wheelset: Cross Country / Marathon
These hubs are Carefree products from German production. Low weight, high rigidity and high-quality materials distinguish this wheel components. Add to that the choice of different colors, freewheeling types and Achsstandards.
BOR hub MD7 front
The 17 mm axle system permits the operation with quick release and 15mm thru-axle and gives the boss a sufficient capacity. The hub body made of high strength aluminum has a brake disc mount IS2000 Standard - 6 hole - and is supported by two industrial ball bearings.
BOR hub MD7 rear
It is supported MD7 rear hub on a 17 mm shaft and a total of 4 bearings. The stable axle allows to adjust this hub anywhere between quick release and 12mm thru axle. The freewheel body made of aluminum transmits the driving forces over three pawls on a tooth made of titanium in the hub body.
DUKE Lucky Jack Carbon
The Lucky Jack by DUKE is a very light and broad rim for cross country and marathon use.
Weighing 310g 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!
