Exceed speed limit
Military test pilots in the 1960s coined the phrase when they tested planes to their limits while risking their lives to the brink. They moved their ball-top throttles fully forward against the cockpit wall to reach top speed, and that's when they used the phrase: Balls to the Wall.
The BTW combo is exactly designed for this kind of racing, where you never upshift out of 53×11 or 12 gears and you're going at your limit, or at the limit of adhesion in the corners. When everyone is riding at the limit of risk. Like the aircraft that inspired the term, the BTW suit uses cutting-edge research and design in the pursuit of speed: analysis through CFD, 3D test dummies, fabric research and testing, lots of wind tunnel testing, and then WorldTour race testing. At the beginning of this research project we were willing to sacrifice comfort in the name of speed, but in the end we used maximum breathability and stretch fabrics that contain a bit more Lycra® fibers so you don't stay completely dry, and the fabric on the shoulders is a bit heavier, and the suit doesn't have a front with a Sanremo cut, so the zigzag break is going to be a bit more challenging.
But all of this is a small price to pay for an incredible THREE PERCENT overall aerodynamic drag savings compared to the fastest Sanremo suit in its class. That 3 percent is what really counts at higher speeds, especially in the 45-65 km/h range. You can also have the BTW suit made in your team graphics through the Servizio Corse CASTELLI program, or purchase it in this secret black ninja version to help you clear your local segments at Strave or on a group ride.
