An HM3X carbon frame with the SOFTEX system

The heart of the Berria NAII BR is based on a frame made entirely from HM3X carbon fibre, made using a construction method Triple Monocoque. This design combines rigidity, lightness and precise handling, with a high degree of integration between the various components.

One of the key features of the NAII BR is its system SOFTEX, which offers 28 mm of travel in order to improve the absorption of vibrations and uneven ground.

The system is integrated into the bike’s design and works with a Avanforce NAII Tibia UD carbon seatpost, which is also specific to the SOFTEX system.

Managers also benefit from:

• a bottom bracket T47 ; ;
• the complete routing of the cables ICS2 ; ;
• a semi-integrated headset OH2S 1-1/2" – 1-1/2" ; ;
• brake fixings Flat Mount ; ;
• a rear through-axle 12 × 142 mm ; ;
• of the derailleur standard UDH ; ;
• with tyres compatible up to 700 x 50C.
