Triathlon Bike - BH Aerolight RC Ultergra Di2
2015 BH Aerolight RC Ultegra Di2. This high-end time trialer is kitted out with top-performing componentry, including Shimano's quick, clean-shifting Ultegra Di2 drivetrain, incorporating the highly efficient Rotor Flow crankset, BH's own lightweight calipers controlled by Vision's aero brake and Evo 55 deep- rim carbon wheel set. The frameset is finely tuned throughout for the smallest possible face to the wind. A very good time trialer.
