BH’s high end road bike for 2011 is the G5. The 2011 BH G5 uses a mixture of premium materials, which includes Toray fiber that is used with Formula 1 racing.
The BH 2011 G5′s lightweight and stiffness is a result from the material lay up process and molding techniques. Finer composite materials and a larger number of carbon layers equal a higher level of sprinting, cornering stiffness and climbing than competitors.
The 2011 G5 frame weighs in at 810 grams, while the fork weighs 330 grams (both unpainted). BH has said a G5 in 54cm with SRAM Red and R-Sys wheels weighs 13.25 pounds.
You can have your 2011 BH G5 road built in four different groupsets: Shimano Dura Ace Di2, Dura Ace 7900, Ultegra, and SRAM Red.
