What is the Sonic Wing?

Cervélo™ Specific Alloy Rear Hydration Carrier. You know those mysterious two holes in a Cervélo™ seatpost? Well, this Carrier will fit in there, a nice tight fit. Is compatible with the Cervélo™ P2Cs, P3Cs and P4Cs. Consider also the Carbon Sonic for XLAB's carbon version.

Trust the professionals that are dedicated to your Hydration and Storage needs. Our carriers are Wind Tunnel Proven and owned by World Champions. They are proven to be the most aerodynamic and versatile in the market today...period.

Lightest Alloy Available

  • Chassis: 64g +/- 1g
  • Chassis w/ Straps: 73g +/- 1g
  • Chassis w/ Hardware: 90g +/- 1g
  • Chassis w/ Hardware & Straps: 99g +/- 1g


Can be inverted for a lower position on the saddle, or keep it upright for a low drag higher position.

Custom Fit

Has 30 different positions available, so that you can have a custom fit position that is both comfortable and aerodynamic. 3 different carrier angles and 5 different bottle angles for each position.


Because the carrier fits on the seat post we have not discovered any seats that you cannot use including the long Fizik, SMP, Selle Italia, Selle San Marco, Terry and others.

ISM when fitting to Cervélos the saddle works well if you use the Cervélo clamp in the front hole of the seat post. If you have the clamp in the rear hole it is necessary to invert the XLAB carrier in order to miss the 2 1/4 inch wide tab sticking down on the ISMs. If you do not wish to invert the carrier  to miss an ISM saddle, then select either the XLAB CARBON WING , SUPER WING, TURBO WING or MINI WING


When installed in the high position, air flows cleanly around the aero seat post. The narrow 5/8" Sonic with open back for air to exit, can save 13 seconds per kilometer in the high position.
