R2BIKE wheelset 29" XC | Zipp MTB Center Lock hubs | ENVE Carbon rims
Application: Cross Country XC
XC racers always want to win and are therefore looking for lightweight yet stable wheels. The combination of ENVE carbon rims and the exceptional Zipp hubs should therefore always be on your shortlist. The fine selection of components guarantees you a high level of reliability and a place on the winner's podium.
Hubs
The ZM2 SL hubs combine durability with high performance. Developed in Germany with the highest precision, they impress with reliable performance even on the most technically demanding XC routes. An optimized sealing system provides effective protection against the effects of weather and increases the service life. In addition, an automatic preload guarantees the correct bearing play at all times, for long and smooth operation of the hub. The 7076 T6 aluminium used offers maximum fatigue resistance. Despite its robustness, the ZM2 SL rear hub is extremely light at 227 grams. In addition, an automatic bearing play pre-adjustment always guarantees the correct bearing play, for long and smooth operation of the hub.
The sophisticated freehub system offers 66 engagement points per wheel rotation and ensures quick engagement with six offset pawls, which are organized in two groups of three pawls each. This means that three pawls always engage simultaneously, ensuring direct power transmission from the pedal to the wheel.
Rims
If you don't want to compromise, here is the perfect rim for your adventures. Light, stable and durable, there are no limits for XC use and your opponents will only see your rear wheel.
ENVE is breaking new ground with the M5 series. Different constructions on the front and rear wheels ensure specific characteristics and bring your full potential to the track.
Particular attention has been paid to comfort. A new rim shape and an improved carbon laminate increase compliance. This allows the rim to adapt better to the surface and absorb shocks. This significantly prevents the rider from tiring prematurely.
The inner rim width has also been increased at the front and rear, allowing the use of very wide tires, which generate more grip and can also absorb bumps better.
The wide hookless bead technology ensures the best tubeless compatibility and high puncture protection. The special shape of the hookless rim flange distributes the occurring forces over a larger area and reduces the probability of punctures by 50 % compared to the previous rim. Lateral crushing is also much easier to absorb, which means that the rim is more forgiving of the occasional riding error.
The spoke holes are specially designed for the nipples supplied. This guarantees even tension and a very solid wheel. The Nyloc insert prevents the spokes from loosening on their own and significantly increases durability.
ENVE carbon rims are developed by ENVE in the USA and manufactured to the highest quality standards at the company's headquarters in Utah. ENVE's engineers have years of experience with the use of carbon in the field of cycling and know what requirements a top product such as these rims must meet. At ENVE, every effort is made to utilize the advantages of carbon and eliminate its disadvantages. Stiff and extremely light rims have been developed in which all fibers can run without interruption, which corresponds to the best possible utilization of the material thicknesses. This principle was perfected for the spoke holes, with continuous fiber strands forming the receptacle for the spoke nipples. Aluminum inserts, which are quite common in other carbon rims, can therefore be dispensed with during production. This reduces the weight and at the same time allows significantly higher spoke tensions, which in turn allow the construction of stiffer wheels.
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.
