I have a 12mm through axle on my bike and wanted a chain support to fit over the axle when the wheel was removed to support the chain for cleaning and lubing.
I got a Petzl UltraLegere Pulley Wheel for about 3 quid from an online climbing supplier. Works perfectly, has an internal diameter of 14.5mm and is made of the highest quality plastic (lives depend on it).
