The Shimano SPD Adapter SM-SH40 w/o Cleat is a practical solution for riders who want to use SPD two-bolt shoes with three-bolt road-style pedal systems. Designed as an adapter plate, it bridges the gap between different cleat standards, allowing you to enjoy the secure, walkable benefits of SPD shoes while still running many popular road pedals. This makes it especially useful for commuters, touring riders, and anyone who frequently walks off the bike but still wants efficient power transfer on the bike.
Engineered with Shimano’s typical attention to detail, the SM-SH40 adapter offers a stable interface between shoe and pedal, helping to maintain a solid connection and predictable engagement and release. Installation is straightforward, using standard hardware and patterns that are familiar to most cyclists and mechanics. Because it is supplied without cleats, it is ideal as a replacement or spare adapter for riders who already own SPD cleats. Whether you are refreshing a well-used setup or configuring a versatile shoe-pedal combination, this adapter adds flexibility and extends the usefulness of your existing equipment.
