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. Nivacrom Steel - Weight: 1900 g
