intended use of the wheelset: Cross Country / Marathon
Absolute Black, a small but successful producers of the British Isles, is expanding its portfolio to an exceptional pair of bosses. The of 7075 aluminum CNC machined hub body is similar in the central part a diamond. All who rely on an extravagant design, look no further. But the hub not only looks chic. Inside work two large ball bearings 6903, which are double sealed and ensure even under heavy use area for continuous and easy motion.
Tested by cyclocross and mountain professionals Marek Konwa and Maja W?oszczowska.
Absolute Black hub Black Diamond front
Light and sturdy mountain bike hub does not shrink even from the toughest conditions. The extravagant milled artwork does not have a weight limit and is therefore fully usable. The two large ball bearings which are sealed twice, ensure continuous and easy motion. The hub can also be converted with a separately sold Conversion Kit subsequently in various Achsstandards.

The power transmission is handled by two toothed discs made of steel. A 26-fold gear transmits sprinted quickly. The movable pulley in the hub body is controlled by a magnet, which makes the system very insensitive. Where there is nothing, nothing can break. The second pulley is integrated in the freewheel body. Through the use of steel, the component has a very high lifetime. At the same time the typical incorporating cassette as in freewheel bodies aluminum deleted. The hub can also be converted with a separately sold Conversion Kit subsequently in various Achsstandards.
The rims of Notubes are probably the most commonly installed when a spitzenklassiger wheelset is requested with lightweight aluminum rim. The rim profile is optimized such that this wheel takes out a proper stiffness from very little material. In addition, the rim Tubeless ready! This means that normal tires can be driven without tube. For this, the rim must only me provided Tubelesstape and the tires are mounted with some sealing milk. By omitting the tube the friction between tire and inner tube and the flexing of the tube is completely eliminated. As a result, the rolling resistance is reduced while simultaneously increasing comfort and grip!
NoTubes ZTR Crest MK3 With the MK3 Notubes brings a further development of their legendary Crest rim on the market. Despite a by 2 millimeters enlarged inner width Americans were able to save 20 grams of weight to the rim and at the same time increase the stiffness. Made possible by the inspired by the Valor carbon rims new rim design. With the increased size of 23 mm inner width of the tire increases in volume and is located at low air pressure stable on the rim. After Notubes Wide Right system the width of Crest MK3 has been optimized for 2.0 inch to 25.2 inch tires. For previous version remained the same over the years is the refined Bead Socket Technology and the superior characteristics Tubeless. An extra light rim, the tire can develop fully and the tire volume increases compared to a conventional rim. This leads to a lower rolling resistance and better damping characteristics.
intended use: Cross Country, Marathon
recommended weight limit incl Clothing: 75 Kg. (28/28 Hole) 85 Kg (32/32 Hole)
NoTubes Arch MK3 The ZTR Arch MK3 was developed with the input of the Enduro World Series teams. Despite an increase by 5 millimeters tremendous inner width compared to Arch EX, the Americans were even able to reduce the weight of the MK3 minimal and at the same time increase the stiffness. By enlarged to 26 millimeters inside width of the tire increases in volume and is located at low air pressure stable on the rim. After Notubes Wide Right system the width of the Arch has been optimized for MK3 2:25 inch to 2.5 inch tires. Compared to the ZTR Crest Arch EX heavier drivers provides more stiffness and reserves in borderline situations.
intended use: Cross Country Marathon
recommended weight limit including clothing. 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!
