FAQ

How do I know if my shoe has a captive nut?

Most modern SPD-compatible shoes have captive cleat nut inserts pre-installed in the sole -- threaded channels that hold the cleat bolt in place during installation without loose nuts. If your shoe has visible threaded inserts in the cleat slot, use this no-nut version.

What is the difference between SM-SH51 and SM-SH56?

SM-SH51 is single-release -- exit requires a lateral heel-out twist only. SM-SH56 is multi-release -- exit is possible in multiple directions including upward and diagonal, making it easier for beginners and commuters. Choose SM-SH51 for secure engagement and SM-SH56 for ease of exit.

How is this different from the SM-SH51 pair with cleat nuts?

The with-nut version includes loose cleat nuts for shoes where the sole does not have captive inserts -- typically older shoes or some touring footwear. This no-nut version is for shoes with captive inserts already installed.
