Wheel set 28 "American Classic hubs | 77 Composites Rim Road Tubular | Sapim CX-Ray | RR
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.

This rear wheel hub is in the form of very long on the market. Changes to the design thanks to its sophisticated design were previously hardly necessary. With external dust seals and sealed stainless steel bearings is ensured the durability of the bearings. For greater durability of lightweight aluminum freewheel body steel profiles were admitted into this, to prevent the otherwise typical biting of individual teeth in the freewheel.
The high quality 77 Composites Products made of carbon are consuming hand-laminated and 100% made in Germany. There are technologies, production techniques and processes applied which are often used only in the aerospace and F1.
The attributes lightweight and stiffness can be implemented almost uniquely with the we have built wheelsets.
77 Composites rim 28 "| 700C Road Roadrunner 25T Tubular
The manufacturer's 77 Composites carbon rim belongs weighing 215g the lightest 28 inch wheels for Tubularreifen. Wheels weighing about 850g are possible without any problems with this type rim. Due to the weight of the outboard rotating dimensions to impellers 77 Composites rims have excellent speed. With a width of 20.5 mm, the rim more than enough lateral stiffness available. In a tubular rims of tubulars is glued to the rim. In the professional competition, this technique has been widely circulated. The tire works with a high flexibility. The result is a very sensitive working sidewall, which provides in combination with the other components of traction, ride comfort and rolling behavior at the highest level.
intended use: Road, Triathlon
recommended weight limit including clothing. 90 Kg (20/24 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. The spokes are protected from the weather by a black surface treatment.
Wheel building at R2-Bike
Our wheels are assembled by our farmers impeller entirely by hand. While the entire structure is placed value 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!
