Lightweight. Easy to get into and out of. Low profile aerodynamics.

Heavy Cleats that get destroyed quickly from just a bit of walking.

Lightweight pedals but cleats are heavy, thus, you do not get the weight savings you calculated you were going to get. All things considered, these are great pedals.

light, infinitely adjustable rotation, quick entry.

require regular cleaning/lubing, high cost (but way cheaper than knee surgery)

Pedal purchase is as personal a decision as the bike itself, maybe more because it makes up two of the five contact points from body to machine. If you like lightweight small platform pedals this is the best I've used. After years using Speedplay X-series pedals a change was needed when I developed knee pain. It’s so hard to know for sure, but it looks like part of the problem was too much rotational float, and a heel wandering outward as my leg got tired. Also the X series cleats wore too quickly, soon allowing the shoe to laterally wobble and canting the shoe. This actually can be good, except that my heel then wandered down/out in the direction of the the cant. Without some limit to the outward rotation, my L leg started to look like I was doing an Elvis impersonation, ouch. Zero Pedals are a huge improvement. The rotational stops on the pedal cleats are infinitely adjustable. The stamped steel cleat springs are tougher/beefier and won’t wear nearly as fast. Wear points are now metal to metal, and composite to composite. With good-quality shoes, I can’t tell that the pedals are not large-platform. Weight difference on my cheap postal scale for a pedal/cleat is only ¾ ounce over an X-1. Pedal entry is very fast because you just step down, most important for me when commuting through Denver at stoplights. The downside is similar to any Speedplay … high maintenance. Because the moving parts are on the bottom of your shoe, they get dirty easily. You’ve got to regularly clean and lube ‘em, especially Zero’s, or risk poor pedal entry/exit and quick wear of the cleat. Using a worn Speedplay cleat will trash your pedal bodies, similarly to a worn chain on sprockets. That said, cleaning/lubing is quick and easy. I really like these pedals, best yet of any I’ve tried. Knee pain is gone.

Speedplay X-1, Old Dura Ace when they were Look style large platform, SPD 747, Onza.

Easy to assemble, light weight, low stack height, easy to clip in, and easy to compensate for leg length differences.

Expensive, but not out of line with other top of the line pedals.

Assembling the cleats on my new Sidi Genius 4 shoes was easy. The float mechanism works and feels similar to SPD and Onzo pedals I have used, except the float itself is a little easier and not self-centering. I think the pedals are easier to clip into compared to my SPDs. Even on my first ride with the pedals, I was clipping in faster than my buddies on Looks (maybe its just my buddies!). Disengagement is similar to other pedals I have used, but the amount of tension is not adjustable. After you pop out, however, there is not much pedal to work with when riding unclipped. The lower stack height of the Zero pedals compared to my old Shimano 747's allowed me to lower my seat several mm. Seat height was the primary reason I bought these pedals instead of Look. I did not want the seat any higher because of limited adjustability of my carbon fork/stem. I also purchased the cleat leg length kit to adjust for a small leg length difference and it worked great. At $10 it was a cheap (and easy to assemble) fix for the problem. I recommend purchasing the Zero coffee stop caps ($10) to protect the large cleat mechanism and to make walking somewhat safer and easier. I do not necessarily recommend purchasing the Ti model over the stainless model. I bought the Ti model only because the stainless model was on back order the weekend I needed the new pedals. The 40g weight savings, and very slight improvement in Q factor and cornering clearance would not be enough to induce me to buy the Ti model if the stainless steel model had been in stock. For those who are concerned with "hot spots" because of the size of the platform, well the jury is still out as I have not ridden on them long enough to have an opinion yet. Bottom line after 4 rides: these pedals work fine without much difference in "feel" from the other limited float model pedals I have used.
