Q & A


One of the fastest jerseys around, second only to a speedsuit, Castelli have now focused on breathability and wicking for this latest iteration of the proven Aero Race jersey.  They have developed the new Velocity Dry fabric, which gives these amazing properties while still being light weight and extremely smooth to the air coming at you trying to slow you down.

The jersey is so aerodynamic, the savings can even be measured, and the result is that there is a saving of around 10-12 Watts over Castelli's own Team jersey.  This equates to around 35-40 seconds per hour at 40Kph.  That is a pretty outstanding number, and even if you aren't a serious racer hitting 40Kph, there is no doubt that it will offer you the path of least resistance through the wind.

Other features are Nervato arm fabrics for more streamlining, with Giro3 grippers there to keep it close fitting and in position no matter how much you are putting the power down.  Silicone grippers around the waist do the same job at the other end, and a full length zip makes it very easy to regulate your temperature, and also easier to put on and remove than a short zip jersey.

One final note is that Castelli have made the fabric more stretchy and better fitting for a wider audience, not just elite pros.  This is not to be underestimated, the fit of a jersey being very important to the enjoyment of your ride.

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.
