Wheelset 29 "American Classic hubs | NoTubes ZTR rims MK3 | Sapim CX-Ray | XC MA 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 of the wheelset: Cross Country / Marathon
The development team of American Classic hubs develop with the aim of being able to offer sophisticated products that can do more than that of competitors. Therefore, AMC equips all hubs with stainless steel bearings and uses a freewheeling mechanism with 6 double-toothed ratchets. The Freilaufmachanik attacks so always over 12 contact points that ensure a reliable power transmission. Thus, cassettes can not nick of aluminum in the lightweight freewheel body that is provided with steel inserts.
American Classic Disc 130 front
This hub is prepared for all circumstances of cross country up to the All Mountain use. The bearings are well protected stainless steel and integrated into the bearing sealing washers and outer dust seals. The bearings are mounted on a 17 mm measuring axle which withstands the loads occurring. About two nuts can be the bearing preload adjust if necessary and perform a reconstruction of the axle uncomplicated.
American Classic Lefty Disc
This hub is prepared for all circumstances of cross country up to the All Mountain use. The bearings are protected by stainless steel and integrated into the bearing sealing discs from dirt. Compatible with all Lefty Lefty and hybrid, for Lefty 2.0 and Lefty SuperMax is an optional adapter for the brake mounting required.
American Classic Disc 225 rear
This rear wheel hub is in this form very long in the market. Changes to this design were thanks to its sophisticated design have hardly necessary. With external dust seals and sealed stainless steel bearings is ensured the durability of the bearings. For the durability of lightweight aluminum freewheel body steel profiles were admitted into this. 3 This prevent the otherwise typical biting of individual teeth in the freewheel.
The hub can be retrofitted with an optional freewheel on the SRAM XD 11-speed standard.
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
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!
