BERG wheelset 29 "Ratheberg 30 Carbon BOOST 1156g
The founders of the still young BERG brand started with a simple mission: They wanted to develop the best possible lightweight products for ambitious MTB marathons and cross-country riders at an affordable price. In order to be prepared for tough racing conditions, 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 absolute top league among lightweight wheels for XC use. The wheels are built around the in-house BERG pair of hubs that, with a total weight of well under 300 grams, form a perfect starting point. The aluminum hubs are visually impressive with their elegant straight pull design and the BERG logo lasered in white. But the hubs also know how to impress with their inner values. The built-in SKF bearings ensure a long service life and low frictional resistance. A toothed pulley freewheel with 45 detent points per wheel revolution guarantees instant acceleration and quick response in technically demanding passages. BERG uses 6 toothed disc springs for even power transmission. In addition to the built-in XD freehub body, a Shimano Micro Spline compatible freehub body is optionally available. If the hubs need to be serviced, they can be dismantled in just a few steps without special tools.
The ultra-light Ratheberg carbon rims rotate around the hubs. Their combination of an above-average internal width of 30 millimeters and a weight of only 280 grams is record-breaking. In practice, this results in wheels that are extremely easy to accelerate and tires that run very stable, even at very low air pressures. In addition, the large inner width allows tires up to 2.7 "wide to be used. The tubeless inner profile ensures a secure fit of the tire on the hookless rim. The low weight of the handmade rims was partly due to the relatively A low profile height of only 21 millimeters can be achieved. The asymmetrical spoke holes with an offset of 2 millimeters ensure the necessary rigidity in the wheel. A reinforced rim bed provides the spoke nipples with secure support and makes the wheels more stable.
The wheels are spoked with Spaim CX-Ray knife spokes at BERG in Belgium.
In order to guarantee the safety of their components, all BERG components have undergone intensive test drives and extensive tests in accordance with the ISO standard in Germany. In order to guarantee the high quality standards in the long term, the tests are repeated on different product batches.
In addition to the 2-year guarantee, BERG offers a 3-year crash replacement with a 40% discount on all components.
