Mountain King with sensational 790 grams!
For 2017, the flat tubular rims and the successful model of AX Lightness, the Ultra 24T has been completely redesigned. The successor, the ax 25T, is now 25 mm deep and still brings in a width of 22 mm with 200 grams on the scale, so that a wheelset weight of 790 grams is realized.
In the ax 25T integrated Logos is aufverzichtet in the rim and has now, thanks to its modified design improved aerodynamics. The braking performance was improved even in difficult conditions by a remote machine and post-processed brake flank continues.
The Ultra 25T wheelset is a true mountain and climbing king as whether Alpine marathon or mountain time trial, was able to prove on numerous race wins.
Despite his sensational weight, the Ultra 25T to exceptional stiffness and stability values that give him a rider weight limit of 100 kg and not just uphill, but also down to make it a secure bank and the absolute weapon.
The rims are developed in Germany by AX Lightness and produced under constant quality control.
It is petty respected it that the laminate is constructed always optimal from highly durable carbon fiber. Damage to the fibers can be avoided, to achieve the maximum stability with minimum weight can. The necessary in the rim holes are therefore 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.
