The Stealth Disc is our answer to the disc revolution, taking Spec to new levels of road performance. This model includes features such as our vibration dampening Elastomeric battery Insert (Di2 models only), and an updated more compliant seat stay and seat-post design to make the ride aero, yet more comfortable than ever. An over-sized ultra-stiff PressFit bottom bracket allows the Premium Shimano cranksets offered to put the watts to the rear wheel efficiently and smoothly. If you enjoy the benefits of riding with a power meter, then spec out one of our factory installed Stages power meters to finish off the build. (full custom builds available upon request/consultation)
