Shimano SPD SM-SH51 Single Release Cleat
$30.00 CAD
The Pro Standard.
When precision matters, the Shimano SM-SH51 is the only choice. Engineered for high-performance off-road riding, these "Single Release" cleats are designed to keep you firmly locked in through technical rock gardens, high-wattage sprints, and muddy CX run-ups. This is the gold standard for riders who demand a definitive, intentional exit from their pedals.
Why the SH51 is the Rider’s Choice:
- Single-Directional Release: Unlike multi-release cleats, these only disengage when you twist your heel outward. This prevents "accidental unclipping" during vertical efforts, jumps, or heavy sprints. Making them essential for aggressive trail riding and racing.
- Cold-Forged Durability: These cleats are heat-treated and cold-forged for maximum hardness. They are built to withstand the constant grinding of sand, mud, and rock that comes with the Toronto gravel and MTB scene.
- Low-Profile Design: The compact SPD interface allows for a recessed fit in your shoes, making it much easier to walk (or hike-a-bike) compared to road-specific systems.
- Crisp Engagement: Provides that legendary Shimano "snap" every time you clip in, giving you the tactile feedback you need to know you're secure and ready to rip.
Technical Specs:
- Release Style: Single-directional (Heel twist outward)
- Compatibility: All Shimano SPD pedals (e.g., M540, EH500, XT, XTR)
- Float: 4° (Provides enough movement to protect your knees while staying efficient)
- Hardware: Includes 2 cleats, 4 bolts, and 2 washer plates.
The Alegro Tech Tip: We spec the SH51 for all our Alegro Racing Division gravel and CX builds. If you find yourself "popping out" of your pedals when you pull up on a climb, it’s likely time to switch from the beginner SH56 to these high-performance SH51s.
Locked in. Ready for anything. Upgrade to the SH51.
