Hub width and mounting specifications make it compatible with forks and brackets that accept an M8 shaft and an internal fork spacing greater than 5 cm. How to choose and install 1. Confirm the wheel diameter matches your current caster. This listing is for the 8 in (200 mm) size; other sizes available include 6 in, 7 in, and 7.5 in. 2. Measure the internal distance of the front fork or the distance between mounting points. The fork inner spacing should be greater than 5 cm. 3. Verify mounting hole spacing is 8 mm and the shaft/thread is M8. 4. Installation is straightforward: remove the old wheel and shaft, fit the wheel and shaft into the fork, and secure with the appropriate fasteners. Notes There may be slight measurement differences due to manual measuring. Please measure your existing wheels and fork before ordering to ensure a correct fit. Solid tire design eliminates the need for inflation and reduces puncture risk while providing stable, nonslip traction.
