XLAB Sonic Wing

The X-Lab Sonic Wing bolts directly to a Cervelo Aero seatpost on the Cervelo P2, P3, and P4. It is an extremely functional, well-designed rear hydration system capable of carrying CO2 cartridges, an inflator, one or two bottle cages, tires, tubes and other items so they are very accessible. The chassis weighs only 66 grams (90grams including hardware) and it made from aircraft-grade structural alloy. The Sonic Wing comes with a pair of X-Straps and includes two discs to cover the spare holes in the seatpost.
