AX LIGHTNESS wheelset 28 "Ultra Road U 25C | Extralite Ultra Front / Rear
With a foot on the Direction MTB Clinchern technology which has already proven itself extensively in MTB WorldCup, AX Lightness now sends the corresponding street version into the race.
With just under 1000 grams in Clincherreifensegment ultra lightweight, ultra Road U 25C comes up with the latest technological features. So the wheels are equipped with a bulbous, 28 mm deep aerodynamic profile. This results in a substantially more homogenous transition to the mounted tire which scores in addition to the improved aerodynamics in particular by a considerably more forgiving handling in a crosswind or gusts. The large air gap of 18 mm can leaven the tires better, increases the contact surface and thereby improves both the grip and the damping of the tire, also due to design decreases the rolling resistance.
Proven As with MTB Clinchern, the rim flanges are either milled or otherwise reworked by machine, but on a piece by hand and laminated with continuous grain. This has the horn on a significantly higher strength and stability, which allows very good emergency running properties. The pronounced edge and Clincherwulst also ensure a more secure grip of the tire, added safety in the event of air loss.
The necessary in the rim spoke holes are not drilled as cheaper wheels through the fibers passes but factory laminated with reinforcements. This increases the workload of all process steps away significantly, however, leads to a much better product, the result: nipple pull-out forces of five tons - which is far more than each spoke, nipple or hub could ever cope!
In the center of the wheels to hub are of Extralite. This coming from Italy masterpieces of lightweight construction are optimally adapted with the help of modern, computer-aided design tools to loads. At the same time waste material is saved and used at less exposed points resistant plastic. The freewheel mechanism relies on a pulley principle in which getting all the gear teeth engage and transmit the drive torques.
For optimum delay with minimum wear pads are recommended, which are tuned to carbon braking surface.
