MAX | Tube
set for special racing bikes made from the exclusive Nivacrom® steel
with exceptional strength characteristics. The elliptical cross-sections are oriented in such a way that the major axes are directly opposed to the highest active and passive stresses. This set has been designed to optimize efficiency under the demands of extreme bads: sprint, time trials, climbing and strong centrifugal acceleration when descending.
