Q & A


The Castelli Stealth T1 Tri Top has been wind tunnel tested to show a 3 minute advantage on a 5 hour Ironman bike leg. Put this on after a swim and get to T2 3 minutes faster than with a standard tri suit. As well as reducing aerodynamic drag it also provides sun protection from UPF 16 and up. The top was designed with the help of former pro cyclist turned engineer Robby Ketchell and his aero testing found that it saves 3:01 for a rider averaging 23mph over an Ironman by improving airflow over the riders upper body.

The Stealth T1 top has all of the same great features as the mens model with the only difference being the Castelli printed logo on the front. Velocity fabric on the front and velocity mesh fabric on the back and shoulders help to reduce pressure drag and at the same time keep you cool. The top can be worn under a wetsuit or donned in T1. Stripping it off in T2 is a quick and easy process.

Note: Please click on the above tabs for the Castelli size guide and technology guide.

Note: Castelli clothing is sized small, Tweeks Cycles recommend you select one size above normal for an athletic fit, or two sizes above if you prefer a more relaxed fit.
