ENDURO BEARINGS HDC-120

HDC-120 - 1-1/8' x 0.25mm Upper Headset Bearing Shim (28.7mm x 34.5mm x 0.25mm) This small shim is a perfect fit for fine-tuning your headset installation. Insert this 0.25 mm-thick spacer between your headset’s compression ring and upper bearing cap to increase the clearance between the bearing cap and the headtube of your bicycle. For adding space between your fork and frameset, try WA 36-150x1 (for 36° 1-1/2” lower headset bearings) or WA 45-150x1 (for 45° 1-1/2” lower headset bearings) between the fork crown and the bearing’s inner race to add 1mm of stack to that area of the bike.
