intended use of the wheelset: Cross Country / Marathon
The hub of the manufacturer DUKE from France combine technology, longevity and fresh design!
Duke hub Mad front
MAD - the front wheel hub - turns on a 17 mm aluminum axle and 2 double sealed cartridge bearings. These originate from the German camp specialists HWG, which stands for high precision and durability. Authentic highlight is the hub - a mix of carbon fiber and aluminum. In the middle section, a carbon body is processed, which is received right and left of aluminum parts.
The side panels are elaborately CNC-milled and have not a gram too much on the scale. Incidentally also small optical refinements can be found in the CNC Design. So the crown of DUKE logo on the side panel as playful milling is for example available.
Duke Super Mad Lefty 2.0
The Super Mad front hub has been developed especially for Cannondale Lefty forks 2.0. She turns on 2 dopppelt gedichtetetn deep groove ball bearings of the German stock specialists HWG, which stands for high precision and durability. In addition, the dirt-prone camp is protected on the fork side by a nylon plate. Authentic highlight as the Mad hub body - a mix of carbon fiber and aluminum. In the middle section, a carbon body is processed, which is taken up on either side of elaborately CNC-milled aluminum parts.
NOTE: The Super Mad is only compatible with the Cannondale Lefty forks and 2.0 Supermax / Supermax 2.0.
Duke Max hub rear
DUKE MAX this Hinte hub - turns on a 17 mm aluminum axle and 4 double sealed cartridge bearings. The originate from the German camp specialists HWG, which stands for high precision and durability. Highlight of the hub, the freewheel mechanism! Work Here 2 toothed discs, which have a 75 times gearing. This ensures instantaneous power transmission and very low idle times. For a permanent feature both sheets of steel are produced. To push the weight to lightweight 220 grams, the hub body is consuming CNC machined. In addition to the unique design and small optical refinements in addition can be discovered. So the crown of DUKE logo on the side panel as teasing detail is present, for example.
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 including clothing. 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!
