Description
Wheelset 29" XC | Duke MTB Straightpull 6-hole hubs | Duke aluminum rims
intended use : Cross Country XC
XC racers always want to win and are therefore looking for light yet stable wheels. The combination of Duke aluminum rims and their indestructible hubs should therefore always be on the short list. The balanced selection of components guarantees you high reliability and a long service life.
hubs
Duke's MADMAX SP hubs are the perfect pivot point for light, stiff and durable wheels. The CNC machined and then black anodized hub body made of 7075 T6 aluminum rotates around three 6902 and one 6802 2RS deep groove ball bearings, which sit on a stiff 15 mm axle and are double sealed. All bearings are placed as far outboard as possible for stable support, which creates additional rigidity. The geometry of the spoke flanges has been optimized in terms of diameter and spoke angle in order to reduce the stress on the spoke heads to a minimum. With their low weight, the DUKE MADMAX SP hubs are a lightweight among the BOOST hubs. A special feature of the hub is the freewheel body made of titanium grade 5 (Ti6Al4V). Thanks to the excellent properties of the material, the teeth could be milled directly into the freewheel body and the number of moving parts was reduced to a special spring and the toothed washer in the hub body. The 70-fold toothing results in a maximum idle travel of 5.14° and is extremely large with a diameter of 35 mm. The large diameter allows optimal torque transmission and the hub is therefore also approved for use in e-bikes. A fundamental point for the reliability of your new hub is the protection from the elements. The special seal between the hub shell and the freewheel body guarantees optimal protection against dirt and water with smooth running that is second to none.
rims
The rims from Duke from France stand for low weight and excellent workmanship. The hookless construction is ideal for using tubeless systems. The reinforced bead means that any punctures can be better tolerated without causing damage. The fairly flat and wide rims reliably support the tire in every situation.
The asymmetrical shape enables more even spoke tension, which further increases the rigidity of the entire wheel.
Impeller construction at R2-Bike
Our wheels are assembled entirely by hand by our wheel builders. During the entire construction, it is important that not only the concentricity is right, but also that the spoke tension is as even as possible. The special care allows us to give a lifetime guarantee against broken spokes, as long as this is not caused by violence!
You will also receive the following services with our wheels:
A universal impeller bag for all common sizes.
A spare spoke + nipple in all required spoke lengths to be able to repair the impeller at short notice even after an accident.
A free initial check of the impeller, where the resulting work is completely free! Only shipping costs are charged.
A crash replacement promise. If your wheel is damaged due to force majeure, we will rebuild your wheel once. We grant a 100% discount on all labor costs and only charge for the material!
