Note: Exway X1 PRO RIOT uses the different pulley from Exway FLEX/WAVE. Please choose accordingly from the options above. And Exway X1 PRO RIOT can only use the Cloudwheel Discovery 105mm wheels right now.
Note: While you changing the wheel pulley and belt to your Exway Flex/Wave, please notice that the belts we provide is a bit larger than stock. So you need to adjust the motor position to make the belt mount suitable. It will also avoid the belt from touching belt cover.
