PORTE rim 29" Rathe 30.6 28-hole UD carbon 240g
New name, same passion: the still young Berg brand becomes PORTE. The founders started the brand 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 equipped for tough racing conditions, no compromises were made in terms of durability when developing the PORTE components. Behind the brand is a small team of dedicated mountain bikers, engineers and bike mechanics from Belgium.
The Belgians have already broken all records with the Rathe 250g rim. Now PORTE is following up with a 240 gram lightweight version. But how can such a low weight be achieved without immediately risking a defect?
The main effect of this development is the patented, asymmetrical rim profile. The dimensions and angles within this enable the perfect balance between strength and material savings. This means that the sidewalls can be made very thin, while the rim base is reinforced with the spoke holders. In addition, the carbon mats have been aligned using advanced shaping techniques so that the forces occurring can be distributed over a large area and point load peaks on the inner structure are virtually eliminated. All these measures enable PORTE to release the rim for a system weight of 90 kg.
The 240g version also has an inner rim width of 30.6 mm. This gives modern cross-country tires a better shape and a more stable fit at low air pressures. This effect is further enhanced by the low height of the rim flanges, which give the tires even more volume compared to other rims with the same inner width.
In order to guarantee the safety of their components, all PORTE components have undergone extensive tests according to ISO standards in Germany, in addition to intensive off-road riding. These tests are also repeated regularly for different product batches during the manufacturing process.
In addition to the 2-year warranty, PORTE offers a 3-year crash replacement with a 40% discount on all components.
