SPD/Mountain Bike Leg Length Shims (LL Shims) are used to compensate for leg length discrepancies with SPD cleats. Our 3 mm LL Shim is made in the USA of high-density plastic to conform to the curve of the sole of the shoe.
Package includes one (1) SPD/Mountain Bike Leg Length Shim, two (2) 14 mm, two (2) 16 mm screws, two (2) SPD Cleat Wedges (which can be "stacked" to create an additional 1 mm of height), and an installation instruction sheet (also downloadable below).
One (1) SPD LL Shim is the
maximum recommended per shoe.
