Stealth Disc

The Stealth Disc is our answer to the disc revolution, taking Spec to new levels of road performance. This model includes features more compliant seat stays 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)
The Stealth is a leader in terms of price and all out performance. We use the exact same groupsets and technology of bikes nearly double the price, and while there are many great bikes and companies in this industry, we feel nobody can touch our personalized service, quality and value…not even close.
