EXTRALITE wheelset 29" CarboCamber 330 | HyperBoost3 F + HyperBoost3 R hubs
More than a decade ago, Extralite broke new ground with the launch of the ultra-lightweight Carbocamber wheelset with hookless carbon rims. With the current CarboCamber 330 wheelsets, Extralite is once again taking the lead among high-end cross-country wheelsets. The weight of the CarboCamber 330 has remained at the extremely low level of the previous version at 1060 grams. However, the rims with an inner width of 30 millimeters have become significantly wider and offer modern cross-country tires up to 2.4" wide a very good shape and support at low air pressures. This makes the CarboCamber 330 even faster and more effective on the trail and in racing. The extremely low weight of the rims could be realized through an improved carbon layer structure with the latest high-end Toray carbon fibers.For the necessary durability, each nipple seat is reinforced.In addition, the asymmetrical rim design with 3 millimeters offset ensures a more balanced spoke tension and sufficient stiffness for drivers up to 90 kg weight (including luggage)
The wheelset is laced with HyperLite bladed spokes made of stainless steel and lightweight aluminum nipples. The spokes have been given an extremely durable black coating. Due to the butting, they are not only very light but also more elastic than conventional spokes. The greater flexibility allows the forces that occur to be distributed more evenly over more spokes under load, thus reducing the impact of forces on individual components. The durability of the impeller thus benefits directly.
In the center sit the Extralite HyperBoost 3 hubs. They have highly optimised, extremely light hub bodies with straight pull hub flanges. The use of straight spokes enables a significantly better power flow. Potential weak points such as the bend in classic J-Bend spokes and cross-loaded spoke bores in the hub are completely avoided! Only high-quality Enduro Bearings industrial bearings are used as bearings, the preload of which is perfectly adjusted ex works. For a later adjustment of the bearing preload, which is rarely necessary, the hubs have a microtuner with which the preload can be adjusted. The biggest highlight, however, is the freewheel mechanism. This always transmits the moments via finely rastered spur gearing. In order to meet the goal of lightweight construction, this gearing is partially integrated into the freehub body and is made entirely of aluminum.
