A little more advanced.

The Shimano SH51 SPD Cleats offer four degrees of float, and more experienced riders will typically prefer these over the Multi-Release SH-56 cleats. They take a bit more to get unclipped, but the added security in rough terrain is a worthy tradeoff.

  • Four degrees of float
  • Slightly greater release angle than Multi-Release Cleats
  • Not compatible with older, M858 pedals

They work

Great cleats!

Be one with the bike

  • Familiarity: I've used it several times

I prefer being attached to the bike, and the circular motion around the BB with clip ins are INFINITELY more efficient than flat pedals. That's my preference, and while I do not have a preference on cleats, these suited my needs, are solid, and continue to work for years! No brainer

Dependable cleat

  • Familiarity: I've used it several times

This is Tyson's wife. I use these cleats with my Shimano SH-RP2 Cycling Shoes in indoor cycling classes and I haven't had any issues. They're easier to click in and out of than the shoes I had been renting from the studio.

Get 'Em

  • Familiarity: I've put it through the wringer

If you are running Shimano pedals, chances are you are using these cleats. Might as well replace them and get that new pedal feel once again!

Once a year

  • Familiarity: I've put it through the wringer

Keep your pedals and cleats tight and fresh! Works on all SPD style pedals and provide secure connection.

Unanswered Question

I am purchasing the GIRO Manta R woman’s shoe for spin class. Will these work for that shoe and a spin bike??
Thank you

They get the job done

    Make sure to screw them tight. If you leave it loose you will have trouble unclipping from your cleat.

    Solid System

    • Familiarity: I've used it once or twice and have initial impressions

    This is a solid cleat that will go the distance without any surprises. I use the Speedplay system on my road bike where I like a little lateral play, but I prefer these for the trail.

    Gotta have them.

    • Familiarity: I've put it through the wringer

    These things last. I'll usually change them out once a year out of habit vs. necessity. Usually, I end up buying them for new shoes which is what I did here. Don't skimp on the SPD compatible clones. They can't match genuine Shimano cleats for precise clip in and release.

    The standard for SPD pedals

    • Familiarity: I've put it through the wringer

    I use these with my Shimano XTs. There are a must have and cannot imagine riding without this set up. Competitive had them on sale so I got a second set.

    SPD is still setting the bar

    • Familiarity: I've put it through the wringer

    I recently switched to SPD's from another cleat. I really like the adjustable tension on Shimano MTB pedals, and these cleats last forever. While you sacrifice a bit of float vs. other cleat / pedal systems, SPD's are easiest in and out while providing a solid platform.


    • Familiarity: I've put it through the wringer

    SPD mountain cleats seem to last forever, or at least a few seasons, but they'll wear out before a set of pedals. That's where these come in. These singe-release cleats are what come stock with your pedals, so you won't be in for any surprises.

    It's a great cleat

    • Familiarity: I've put it through the wringer

    I've never known anything besides SPD cleats/shimano pedals, but they work great so why mess with perfection. The cleats are basically indestructible. Also, the ability to adjust the tension on the pedals is a huge plus.

    Why stray from the best?

    • Familiarity: I've put it through the wringer

    I first used SPD pedals on the mountain bike in 1990 and they were such a big step forward compared to toe straps. I never looked back and I have used clipless pedals on the mtb ever since.
    I did try another brand pedal to shed a little bit of weight, but Shimano SPD's are just simply better. Adjustability, stiffness and a large platform.
    A big plus are the cleats, which last for ages and do not need to be replaced as often as the competition.

    SPD is the benchmark

    • Familiarity: I've put it through the wringer

    Affordable and durable, what more can you ask of a cleat.

    Can't go wrong with SPD

    • Familiarity: I've put it through the wringer

    What can I say? It's the classic SPD mountain cleat. They have bit of side to side float to keep it easy on the knees. They last a really long time too. I've got a year of regular riding on my current pair and despite showing some signs of wear they still clip in and out easily whilst retaining that signature, secure SPD feeling when clipped in. I much prefer SPD to Crank Brothers or Time because the feeling on the pedals is more secure while still maintaining easy of entry. There's no question when you clip in either because there's always a definite "CLICK."

    I'm stuck, to my pedals

    • Familiarity: I've put it through the wringer

    After many months of using my old cleats and wearing them down from clicking in, hiking around to scout lines, or jsut hanging in the parking lot it was time to replace my old cleats. These things happen, luckily some bike parts aren't as expensive as others. I also like to keep an entire cleat/bolt/slider set up in my pack on rides, if you lose a bolt it can end a ride in a really unfortunate yet preventable way.

    New shoes = new cleats

    • Familiarity: I've put it through the wringer

    These cleats last a long, long time. I don't usually move them between shoes so when I get a new pair of shoes it's time to get a new pair of cleats. Be sure to use grease when installing them, and don't over torque them. Doesn't hurt to carry a spare one in your tube wrap or hydration pack in case you lose a bolt or entire cleat on your ride.

    Best Pedal/Cleat Interface

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    To me, these cleats are part of the best interface for 2 bolt (MTB) configurations. They enter/exit reliably and predictably, and the cleats themselves tend to last longer than others I've used.

    Yesterday, Today, Tomorrow.

    • Familiarity: I've put it through the wringer

    The pedals have gotten better and better, but the cleats have been the same for decades. I buy a set when i get new bike shoes, which is a little too often.
