Spears Racing Aluminum Swingarm Spools:These spools are CNC machined from Aluminum. Rust-proof mounting hardware are included. The grooves on these spools at the point of swingarm stand contact are deep so the engagement is solid, which makes it impossible for your bike to fall off the stand under normal use.
