Review for XLab X-Nut – 2019
An excellent way to hold your Xlab CO2 cartridges and Xlab CO2 adapter. Mounts securely to the rear of the Saddlewing or Flatwing. Makes inflating tires a snap during training rides or out on the race course. Holds up to two CO2 cartridges. Made in the USA. Color Black. Hardware included.
