XLab Carbon Sonic Rear Mount System

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

Why the Sonic Wing? Don't buy other Cervelo™ specific rear hydration carriers. Why? For all the reasons you will read about below. Plus, don't forget our business is the Hydration and Storage business and nothing else. 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.

XLab Carbon Sonic Rear Mount System Specification:

  • Lightest Alloy Available Chassis: 64g +/- 1g
  • Chassis w/ Straps: 73g +/- 1g
  • Chassis w/ Hardware: 90g +/- 1g
  • Chassis w/ Hardware & Straps: 99g +/- 1g
  • Bi-Position Can be inverted for a lower position on the saddle, or keep it upright for a low drag higher position.

Custom Fit - 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.

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

Fastest - 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.

  • CNC Machined from US Aircraft Grade Structural Alloy

  • AntiSway Design: Compact, Dual Stabilizers, Energy Saving.
  • Easy Installation.

This carrier is designed to mate to the spare holes on the back of the Cervelo aero seatpost as found on the P-series bikes. The S-series do not use the same seatpost, so do not have the mounting points required.
You should opt for a rail mounted version, such as the Super Wing (link below)
