Ultra 28C

Ultra 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 18 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 13 bar prior to release which is a testament to their extreme stability.

All of this make the Ultra 28C to the absolute king of mountain!

All of our wheelsets are built to the tightest tolerances and with extremely high spoke tension by hand in our company in Creußen, Bayern, and individually checked before being able to call themselves a real ax-lightness wheelset:
An amount of work that is reflected in the final product and co-determines its extraordinary qualities!
