When BH introduced the integrated seat mast four years ago it created a revolution in the bicycle industry. Others are still following our lead.The new G4 is the ultimate riding machine.

Its adjustable (no cutting!)integrated seat mast, advanced monocoque construction and nanotechnology composites allow us to make a frame that sets a new target for light weight but still has the characteristics demanded by discriminating cyclists.
It is an extraordinary climber, has the stiffness to excel in sprints, the stability to pull away on the descents and the comfort needed to get the professionals of the 2008 AG2R team through three weeks of the Tour de France.
