¡§ Aeris Pro ¡§ , the Professional X'country ride's best choice, equipped with the upgraded super light and high performance cartridges, designed by BOS Engineering Suspensions.

BOS is very well known in MTB racing for its great performing products, mostly seen in downhill, where the French company won many world titles. But BOS also provides high performance racing dampers for official programs in car racing, such as WRC or Rallye Raid. They have been three ti me s World Champion in JWRC, and won three Dakar Rallyes in a row. Spinner asked BOS engineers if they could design a high perfpormance cartridge for the Aeris, they im me diately understood that there is a lot to do to improve X-country front suspensions. The BOS internals mounted in the Aeris has been designed specifically for this fork, and are the first X-country cartridge made by thosedamping specialists.

The cartridges feature a three positions compression adjust me nt (soft, hard, locked), very simple and easy to use, to set up the fork while riding in just one second. When fully closed, this compression setting locks out the fork, but remains efficient on very hard bumps, for security reasons.

On the bottom on the fork, the rebound adjuster acts also slightly on compression, it allows to set up the fork more precisely. Once the setting is made, you just have to play with the upper knob.

This way of thinking X-country suspensions looks smart, and makes sense for all demanding XC riders. But, as for all BOS products, it deserves to be tested on the track !
