I have an XLab Flatwing and XNut for sale. The Flatwing is the low-mounting version of XLab's behind the seat bottle holders, so it is more aero than other models and won't hook you as you mount and dismount.

The XNut connects to the Flatwing and holds 2 CO2's and a microflate.

I think I have the XStraps around as well, and if I can find them I'll throw them in free.



$20 plus $5 shipping. Microflate, CO2, and bottle cages not included.
