Swing axle / straight axle 0.9mm stainless steel shim. Necessary if you find you need lots of paper gaskets to shim your axle tubes. Rather than fitting 10 or more paper shims, this stainless steel shim will reduce the amount of paper shims needed.
You will need at least 1 paper gasket each side of the steel shim to ensure an oil tight seal. This is for a pair of shims.
