What does the sound of an electronic gear shift have in common with the pop of a champagne cork? Pure pleasure, perhaps? The 795 BLADE RS Disc Carbon Champagne Mat Glossy aero bike, resplendent with SHIMANO Ultegra Di2 groupset and ultra-efficient hydraulic disc brakes, is here to prove it. Possibly because the frame, made primarily of high modulus carbon fiber, weighs barely more than a bottle of bubbly.
