Catrike Tube Measurements
RPDX sells lots of useful and fun mounts, so it’s critical that you know the diameter of the tube you’re mounting to. So, we’ve made this handy spinny thing for you with all the tube measurements!
Here are the same frame tubes diameters in table form. We’ve also included the measurements for our TC Assist Arms and the Catrike Assist Arms.
