2011 Bergamont Bikes @ Eurobike 2010

 2011 Bergamont Straightline Team

"Although the Straightline is not a new bike to the Bergamont lineup, it has seen some pretty significant reworking over previous years to produce a sleek and neat frame that incorporates a load of new features.
New for 2011 is this Co-Ax pivot. It aims, like others using a similar design, to keep the suspension active under braking by separating out the suspension and braking forces. This photo shows a bolt through axle, but production bikes will come with custom made Maxles to cope with the width of the dropouts. Notice the rear derailleur cable which is routed through the chainstay to keep it out of harms way.
A Fox RC4 comes standard in 9.5" x 3.0" producing 220mm travel at an overall leverage ratio of 2.7:1. The rocker design has been changed over the 2010 model to create a less progressive curve to work with current shocks, but has approximately 20% increase in rate over linear by the end of the travel. The shock now also mounts to the swing link with bearings to reduce friction and improve small bump compliance"

 2011 Bergamont Big Air MGN

"Travel at 190mm comes from a 2.75 stroke shock to create the same overall leverage rate of 2.7 to 1 as the larger bike. Although the bare frame weight is only 100g or so less than that of the downhill race machine, the Big Air is spec'd with a Rock Shox Vivid Air to save significant weight there. In fact, there'd be very little to stop you doing the same with the Straightline to save some weight there too if that's your bag"
