FSA Compressor plug

Every time someone messes up an expensive full carbon fork by whacking a steel start nut inside the steerer, a dozen kittens die. Please don't kill kittens. FSA Compressor plugs are proper complete top assemblies for carbon steerers to replace the traditional top cap/star nut assembly. Includes integrated cap, bolt, and expander. The 1 1/8" size fits carbon steerer tubes with an inner diameter of 21mm to 26mm, and 1" fits most 1" threadless carbon forks. Specifications • 1" or 1 1/8" • includes alloy top cap, bolt and expander
