AX - Lightness Ultra Disc 28C

Ultra Disc 28C - A completely new development! Thanks to a CfD-optimized rim profile our 28C Clincher rims offer an exceptional aero performance that matches those of significantly deeper rims.
The low weight, which so far has only been reserved for tubular rimsm makes them miraculous accelerators and very reactive. The high stability is responsible for not wasting a single bit of energy or and a high steering precision.
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 make the Ultra Disc 28C the absolute king of mountain!
