Treks Madone SL 6 Disc carries forward the advanced aerodynamic performance & all-around ride quality as other Madone road bike models, but it keeps the price in check with a standard stem & aero bar set up for adjustability. Its the ultimate racing bike at great value, with extraordinary race performance, aero wheels, a road-smoothing Iso Speed decoupler, powerful hydraulic disc brakes & the sleek look that screams for speed.
