The AS-A01 A-head spacer from XLC is a conical shaped spacer for a semi-integrated headset. The shape is perfect for protecting the bearings it houses from nasty road grit and water that would otherwise corrupt the bearings if it was able to break through the seal. As a result, the XLC AS-A01 spacer is best used on city, trekking, MTB, road and race bikes. Made from aluminium, the spacer weighs 31 g and stands at 18 mm high with a diameter of 1 1/8 inch. It is an especially good seal for your bearings if you clean your bike regularly. This is because it prevents any bike wash or spray from getting in the headset and damaging your bike from the inside out.
