The ‘BTW’ of the Castelli BTW Speed Suit stands for ‘Balls to the wall’, an expression used by 60s pilots to denote times when they pushed their planes to the limit. This speed suit is intended for days when you too are going full throttle and giving the race everything.
This incredible suit was developed with the assistance of Computational Flow Dynamics (CFD) analysis, 3D test mannequins and wind tunnel testing, not to mention real-life World Tour testing. The result? An amazing 3% total aero drag saving in the 45-65 km/h (28-40mph) range, just when you need it in the toughest, closest race.
The minimalist, aerodynamic short section is form fit for improved pedal dynamics, with raw cut laser leg endings for added luxury. Meanwhile, the upper is cut with race position in mind, with mesh sections that not only improve the symmetry of the suit but help manage heat and moisture.
All of these features combine to make this one of the fastest speed suits Castelli has ever made. Weighing in at just 228g (M), it is finished off with the brand’s best Progetto X² Air Seamless Seat Pad, for all-day comfort as you race.
- Designed for optimal performance without sacrificing comfort
- Polyester blend construction with elastine
- Extensively tested to deliver the best possible aerodynamics
- Built around the Progetto X² Air Seamless Seat Pad
- One of Castelli’s fastest models
- Weight: 228g (M)
