As a year-round rider in Portland, Oregon, I deal with rain, slick streets, and steep weekend climbs. These rides test both my balance and my bike gear. I first compared the Shimano SH51 vs SH56 after a few awkward stops where I couldn’t unclip fast enough. Sometimes I even popped out mid-climb without warning. After riding hundreds of miles on both dry trails and wet roads, I saw how different these cleats really feel. In this guide, I’ll show you what sets them apart so you can find the one that fits your rides and your comfort best.
Is the Shimano SH51 SPD Cleat Set Good?
Yes, the Shimano SH51 SPD cleat set is good if you want a firm and secure connection to your pedals. From my testing, these cleats feel stable under pressure and only release when I move my heel outward. That single-direction release type gives me confidence when I’m riding harder trails or pushing power on a climb.
When I first tried them, I noticed how solid the hold was compared to multi-release cleats. There’s no random disengagement, even when pulling up hard on steep sections. For me, that security matters because the last thing you want is your foot popping out when you’re standing on the pedals.
The cleats offer about 4 degrees of float, which gives my knees some comfort while still keeping me locked in. Over longer rides, I felt less strain compared to using a zero-float setup. The black finish looks clean out of the box, though it does wear with use.
In terms of compatibility, I tested them on both my Shimano M520 pedals and an older Deore XT set. They clipped in smoothly every time, proving they’re designed to work seamlessly across Shimano SPD pedals.
From my experience, these cleats are best for experienced riders who want security and efficiency. Beginners may find the single-direction release tricky at first, but if you already have some time on clipless pedals, the SH51 will feel natural.
What I Like
- Secure hold without surprises
I like that the SH51 gives me a firm lock. During a sprint or a rough trail descent, I never had a moment where I thought my shoe would slip out. That peace of mind is worth a lot. - Durable and reliable build
The material feels strong. Even after months of use, the release action is consistent. I’ve walked a little on pavement with them, and while I don’t recommend it often, they still held up well. - Knee-friendly float
The 4 degrees of float strike a nice balance. My knees can move slightly, which reduces fatigue, but I still feel locked in enough to transfer power efficiently.
What Could Be Better
- Less forgiving for beginners
The single-direction release means you must twist outward every time. In a panic, some riders might find that harder compared to the SH56 multi-release cleats. - Finish wears quickly
The black coating looks sleek at first but shows scratches and wear fast, especially if you walk on rough ground. - Limited versatility
If you ride both indoors and outdoors, the SH56 might give more release options. The SH51 feels more specialized for riders who already trust clipless pedals.
Recommendation
If you’re a mountain biker, indoor cyclist, or someone who values a secure pedal connection, the Shimano SH51 cleats are a great pick. They’re ideal if you’ve moved past the beginner stage and want more control over when and how you disengage.
For riders in the US who use spin bikes indoors, these cleats work well since many gym pedals are SPD-compatible. But keep in mind, they demand a little practice before clipping in and out becomes second nature.
From my personal experience, I’d recommend:
- For beginners: Start with SH56. They’re easier to release in multiple directions and reduce the fear of tipping over.
- For experienced riders: Go with SH51. The security and firm engagement make a big difference, especially on challenging trails or when you want maximum efficiency.
In short: the Shimano SH51 SPD cleat set is not flashy, but it’s dependable. It’s the kind of gear you install once and then forget about—until you realize it’s been quietly doing its job ride after ride.
Is Shimano SH56 Good?
Let’s talk about the Shimano SM-SH56 SPD Cleat Set — the cleat I’ve tested, used, and trusted for easy, worry-free rides.
If you’re someone new to clipless pedals or just want a safer way to learn, the SH56 is honestly one of the best options. When I first switched from flat pedals, this cleat made the whole process feel natural and not intimidating.
What stood out to me most is the multi-directional release. Unlike the SH51 (which only releases when you twist your heel outward), the SH56 lets you unclip by moving your heel outward, inward, or upward. That flexibility makes a big difference — especially when you panic-stop or lose balance. It simply pops out when needed.
From my testing, the 4 degrees of float provided noticeable knee comfort. It gives your legs just enough room to move without feeling locked in. That’s why many commuters and touring riders prefer this cleat. It adds security without stiffness.
The heat-treated forged steel build feels tough and durable. Even after months of clipping in and out, mine still looks good. And yes — it’s that classic silver color Shimano uses for their multi-release cleats.
I also like how compatible it is. It works with nearly all Shimano SPD pedals, whether you’re on a mountain bike, indoor spin bike, or just commuting around the city. In the US, I’ve seen these used a lot in spin studios (like Schwinn IC4 or Echelon bikes) because they make clipping out super easy for beginners.
Overall, my experience tells me this cleat is built for riders who value confidence over stiffness. It’s not about being “locked in” — it’s about riding comfortably and knowing you can unclip anytime without panic.
What I Like
- Beginner-Friendly Multi-Release Design:
From day one, I could clip in and out without worrying. The multi-directional release feels natural and forgiving — great for anyone learning clipless pedals. - Smooth Knee Comfort:
The 4 degrees of float really help reduce stress on the knees. On longer commutes, I felt less stiffness and more natural movement compared to single-release cleats. - Durability You Can Trust:
The heat-treated forged steel makes this cleat solid. After several months of testing on my MTB and spin bike, the edges still feel sharp, not rounded off. - Perfect for Everyday Use:
Whether commuting through town or spinning indoors, these cleats handle both with ease. I’ve used them in casual shoes and MTB shoes — no issue with fit or release. - Compatibility Wins:
I tried them with Shimano’s PD-M540 and PD-ME700 pedals — both worked flawlessly. If your pedal says “SPD,” this cleat likely fits.
What Could Be Better
- Not for Aggressive Trail Riding:
The easy release can sometimes feel too easy on rocky terrain. Advanced riders might prefer the SH51 for a tighter hold. - Wears Down with Heavy Walking:
Like most SPD cleats, constant walking on hard pavement can wear them out faster. Using cleat covers could help extend life. - Slight Float Adjustment Limit:
The 4° float feels great, but there’s no micro-adjustment option. Riders who like precise tuning might miss that feature.
Recommendation
If you’re new to clipless pedals, this is the cleat I’d recommend — hands down. The Shimano SM-SH56 SPD Cleat Set takes away that fear of falling or getting stuck when stopping suddenly. It’s perfect for beginners, commuters, and touring riders who want to feel secure yet free on the bike.
For US cyclists, especially those using indoor bikes like Schwinn IC4 or Echelon, it’s a smart pick because it clips out effortlessly. You’ll spend more time focusing on your ride and less time worrying about twisting your foot the right way.
If you’re into mountain biking and need that locked-in feel for aggressive climbs or descents, you might outgrow it and prefer the SH51. But as a first cleat or an everyday commuter setup, the SH56 nails the balance between comfort, control, and safety.
So yes — after testing it across different setups, my verdict is simple: Shimano SM-SH56 SPD Cleats make learning clipless riding feel safe, natural, and confidence-boosting.
Detailed Comparison: Shimano SH51 vs SH56
I’ve used both the Shimano SH51 and SH56 SPD cleats on my bikes for months — switching between trail rides, commutes, and indoor training. At first, I didn’t think cleats could feel that different, but trust me, they do. Each one has its own personality — one feels firm and locked-in, while the other gives freedom and comfort. Here’s what I found after real-world testing both.
Release Type: Shimano SH51 vs SH56
The SH51 has a single-direction release, meaning you twist your heel outward to unclip. It’s great for riders who like a firm, confident connection with the pedals. The SH56, on the other hand, offers multi-directional release — you can twist your heel outward, inward, or even pull upward slightly.
In my rides, the SH51 felt more secure, especially on bumpy mountain trails. But the SH56 was far more forgiving for quick stops and low-speed wobbles. I’ve had moments in traffic where that easy multi-release literally saved me from tipping over.
My experience: SH51 keeps your foot firmly in place — perfect for confident riders. SH56 makes learning clipless less scary and far easier.
Rating:
SH51 – 9/10
SH56 – 8.5/10
Security: Shimano SH51 vs SH56
Security feels different depending on what kind of riding you do. The SH51’s single-direction hold gave me a strong connection that felt rock-solid on climbs. The SH56’s easier release, though, trades a bit of that firmness for confidence when unclipping.
For mountain biking, I preferred the SH51 — my foot never slipped unintentionally. For commuting or touring, the SH56 made every stoplight smoother since I didn’t have to think before unclipping.
My experience: SH51 wins for locked-in performance. SH56 wins for peace of mind.

SH51 – 9/10
SH56 – 9/10
Foot and Knee Comfort: Shimano SH51 vs SH56
Both cleats offer 4 degrees of float, giving a bit of side-to-side movement to reduce knee strain. I noticed this most on longer rides — my knees felt relaxed and natural with both cleats.
However, the SH56’s smoother release angle adds a slight comfort advantage. I could shift my foot more freely without that “snapping” feeling when unclipping. The SH51 felt a bit stiffer, which some riders (especially racers) might prefer for control.
My experience: SH56 feels a touch kinder on the knees. SH51 feels more performance-oriented.
