BERG wheelset 29" Ratheberg 30 Carbon BOOST 1130g
The founders of the young BERG brand started with a simple mission: They wanted to develop the best possible lightweight products for ambitious MTB marathon and cross-country riders at an affordable price. In order to be prepared for tough racing use, no compromises were made in terms of durability when developing the BERG components. Behind the brand is a small team of committed mountain bikers, engineers and bike mechanics from Belgium.
The BERG Ratheberg wheelset is in the top league of lightweight wheels for XC use. The wheels are built around the in-house pair of BERG hubs, which with a total weight of well under 300 grams form a perfect starting point. The aluminum hubs impress visually with their elegant straight pull design and white lasered BERG logo. But the hubs also know how to impress with their inner values. The built-in SKF bearings ensure long durability and low frictional resistance. A toothed disc freewheel with 45 locking points per wheel revolution guarantees instant acceleration and quick response in technically demanding passages. BERG uses six toothed disc springs for even power transmission. If the hubs need servicing, they can be disassembled in just a few steps without any special tools.
The ultra-light Ratheberg carbon rims rotate around the hubs. 270g with an above-average inner width of 30mm is definitely a world record. In practice, this results in an extremely easy-to-accelerate wheel. In addition, the large inner width allows tires with a width of up to 2.7" to be used, which can be perfectly supported in the hookless rim profile. The low weight was achieved, among other things, by the relatively low height of only 21 mm. For the necessary A reinforced rim bottom and the asymmetrical cross-section, which allows the spoke tensions on both sides to be adjusted, ensure rigidity in the wheel.All these measures enable BERG to release the Ratheberg 270 for drivers up to a body weight of 90 kg.
The wheels are laced with Spaim CX-Ray bladed spokes at BERG in Belgium.
In order to guarantee the safety of their components, all BERG components have undergone extensive tests according to ISO standards in Germany, in addition to intensive off-road driving. These are also regularly repeated for different product batches during the manufacturing process.
In addition to the 2-year guarantee, BERG offers a 3-year crash replacement with a 40% discount on all components.
