Pretty good cleats
I bought a pair of these (Crank Brothers) when they first came out and installed them on a pair Specialized Recon 3. As others have mentioned the screws are too long and protrude into the shoe a small amount. I fixed that by using the screws from the stock cleats.
The titanium alloy in these cleats doesn't move the same as the brass in the stock cleats, but it's not bad. If anything it's better.
I bought a second pair of cleats for a pair of Chrome Kursk AW shoes. Those clears were different than my first pair, they didn't engage or disengage the same and generally felt a little different.
It took me a long time to realize both sets of cleats were different heights, that it wasn't just a difference in shoe soles. I have two pair of cleats and rotated them around 3 pair of shoes, the third being a pair of (PEdALED branded) Fizik Terra.
Just a moment ago I reached for a caliper after finally noticing the difference in the cleats and sure enough, they are different heights. I have no idea which are the new ones or the old ones.
On a positive note, they last a very long time. I can't tell the old from the new cleats based on wear.
I plan to keep using these and even buy more.
