AX - Lightness Ultra 28C
Ultra 28/45C - A completely new development! Thanks to a CfD-optimized rim profile our 28/45C Clincher rims offer an exceptional aero performance that matches those of significantly deeper rims.
Front shallow and light, rear with medium depth - for minimum weight and minimized wind influences at a maximum performance!
The massive width of 26 mm is responsible for a high stability and stifness. The huge internal width of 16.5 mm allows the tire to evolve in a very advantageous shape that not only allows to ride with a lower pressure without bulking under load or in corners, but at the same time increases the comfort and yields a reduction in rolling resistance.
Each rim us individually tested at a tire pressure of 12 bar prior to release which is a testament to their extreme stability.
All of this makes the 28/45C to a total all-arounder!
