Blue anodized aluminum spacers for 1" threadless/threaded headsets.
NOTE: These are for 1" threadless headsets/forks which are typically MINIs, MTB, and Road Bikes. They can also be used to take up space on 1" threaded systems. These do NOT fit "regular" threadless BMX bikes (which use 1 1/8"). As always, if you're unsure of which size you have, measure the outer diameter of your fork steer tube.
Brand new, never installed - these were purchased in bulk so there is no retail packaging.
