"I've tried a whole bunch of different pedals and never found a pair I completely liked until these. Others I've tried are Time, Campy, Shimano SPD, and Eggbeater.The Speedplays are unique in that they have simply switched roles of pedal and cleat. What would normally be considered the pedal is attached to the shoe. The simple cleat mechanism is attached to the pedal. The advantage of this is that it allows the pedals to be much more firmly attached to the shoe sole, spreading the contact and load area much wider than the typical three-point systems for other pedals.Secondly, Speedplay have separated the adjustment axes so that X, Y and theta (rotational) adjustments are made independently of one another. With most rival systems, X and Y positioning is a cumbersome and inaccurate adjustment whereby all the locking screws have to be loosened and the cleat carefully wiggled to what one thinks is the correct position in one direction while trying to keep the cleat in the same position for another. With Zeros, any changes can be carefully controlled to a level of precision that is difficult with other methods. On other systems, theta is either controlled by the locking tension, or incorporated into the X,Y adjustment, making it even trickier. On Zeros the theta adjustment is controlled by two small screws on the cleat body that precisely limits the amount of yaw clockwise or anticlockwise from a center-point (up to 15 degrees).The locking mechanism is positive, but takes a little getting used to, since it is a sort of twisting-in action to engage the cleat. Once locked, I've never had a cleat spring free under load. So far I've ridden 10,000 miles on the same pedals and cleats. The cleat bases are now well worn, but the locking mechanism is as positive as ever.The one drawback I've experienced is that, because the cleats contain the locking mechanism, they are prone to collecting dirt or mud when not on the bike. This can sometimes interfere with the engagement when you get back on the bike. I invested in a pair of rubber cafe covers, which I recommend that you use diligently when getting off the bike. I also got into the habit of tapping the base of each cleat on the road just before getting on the bike (a sort of double-tap dance with each foot). It's been several months since I had any issues engaging the cleats using this method.I can ride in these pedals all day (7-8 hr rides) without any pressure points developing, which is a first for me. I've had them just over 10 months and covered around 10,000 miles on them with no issues at all. Dialing in the pedals to your particular preference is easy and can be incremented over several rides to find a best fit. For me, they're the best pedals on the market.One issue I've recently encountered building up a new bike appears to be availability. Speedplay markets various colors for the Zero stainless. [...]"

"I used SPDs, and I still do on my MTB. But I wanted something that would be easier to clip in and out for my road bike (you know, when you're in the left turn lane with 10 cars behind you and the light turns green). Its pretty easy to clip in and out, except it seems to require a fair amount of pressure to clip in. If you're under, say, 140 pounds you're gonna need more than just passive weight to clip in. The cleat to pedal interface is rather sensitive to dirt and such too. It doesn't take much to keep you from clipping in, so a fair amount of care must be taken when your walking around on anything but asphalt or concrete. If you're going to buy this pedal, also get the cleat covers for walking around."

"After using the X series Speedplays for a while, I switched to the Zeros and was pleasantly surprised. The Zeros provide a noticably more solid engagement than the X series.



Great cornering clearance, easy to clip into and out of, and low stack height make these a great set of pedals. As noted, they need to be installed as per Speedplay's instructions.



The only negative experience I've had is that they seem to be sensitive to road debris that might be picked up while unclipped at a stop sign/light. It doesn't take much debris to make engagement difficult."

"Before I bought these I read a boatload of reviews on this system. I liked the idea of dual sided entry. I had previously used KEOs and too often found myself trying to find the top when starting out in traffic (must've been stage fright). I was intially surprised at how difficult they were to get into. (I'm no featherweight either) I'm not sure if its a factor of cold winter temps. As I've been using them they have gotten easier to get into.



They are getting broken in, as they get more use they are getting better. Most importantly there are no hot spots like I used to get when using the SPDs. I also really like the adjsutable float. With the KEOs you needed to change cleats to change float. These are two screws on each foot."

"I peddle with confidence right through the corners. I purchased the grease gun and service them as necessary. Speedplay has great use and maintainance instructions and support. Easy in and out. I have never pulled out in a sprint. Cleat is adjustable for bike fitting."

"Been using these pedals for 3,500 happy miles, and they have worked very well throughout. Cleats must be installed correctly and not over-tightened, or they won't engage properly. Requires dry lube (White Lightning or similar wax-type lube) about every other ride)."
