So I had a pair of Shimano road pedals given to me. PD-A515 is stamped on the cleat part of the pedal. I'm trying to find cleats for these pedals. I was under the assumption all spd cleats were compatible but I'm not really sure. Any help on what cleats I need is appreciated. I've always used eggbeaters (even on my road bikes) but thought I'd give these a try. Thanks

Those pedals are old enough to vote. But they're still SPD, so you can use SM-SH51. When the A515 were being made, they also had the SH-SM55 multi-release cleats, but those were phased out ages ago. No idea if the current SM-SH56 will work.

LOL! Maybe I'll just invest the money towards something more mondern then. Thanks

These are your standard SPD pedals. MTB

Not road. Any modern spd replacement cleat will work.

Don't waste your money.

Your half right, any SPD cleat should work. But they are road pedals, not MTB.
Different SPD cleats will have different amount of float, so you might have to experiment a bit to find what you like. You'll also need shoes that can have a SPD mounted.

And, if you use them on a pair of shoes that has a smooth sole, you'll want a set of 'pontoons' to go with them.

I had a set of these pedals on a bike years ago, never really liked them for road pedals, they go on the trainer if I need them.

Well now I am right confused. Is they is or is they ain't road pedals? And if they is, why would MTB cleats work? I'm not going to go look it up. But I think to be helpful to the o.p. someone should. Get it all straight and write a /thread post.

They are a single sided pedal marketed as being intended for use with road bikes but they use SPD mtb type cleats.

That PD53 reflector unit is great.

shimano marketed them as road pedals, but the cleats are interchangeable with the mountains.
