For as long as fitters have been tweaking riders’ set ups, there have been multiple ways of dealing with leg length discrepancies. Most of us probably take for granted that our legs are roughly the same length, but for others it’s a big enough issue that special equipment is needed. Speedplay has long offered shims to fit under their road cleats to equalize the distance to the pedal, but the nature of mountain bike cleats made this same technique a bit more difficult. It’s one thing to have a large flat road cleat sticking out a few inches from your shoe, but a small pointy metal cleat is a different story.

Fortunately, the design of the new SYZR mountain bike pedal allows Speedplay to flip the fit and build the distance into the pedal rather than the cleat…

Speedplay’s new SYZR pedal uses a fairly radical design with the float built into the cleat which allows a more firm connection between the pedal and cleat. That not only supposedly improves energy transfer, but it creates a construction that uses two separate metal plates attached to a composite body. It’s that separation between the two halves of the pedal that allows for their new take on leg length discrepancy. Rather than shimming the cleat, the actual pedal body itself is enlarged by 1-2mm per shim which makes for a wide range of fit. Theoretically, this should make clipping in just as easy, and the range of adjustment is limited only by ground clearance. The SYZR is also available with 5 different spindle lengths to really tune in pedaling dynamics. Firm details on pricing and availability weren’t yet available, but the standard pedals sell for $165 (Chromoly), $199 (Stainless), and $389 (Titanium).

    Any indication on how many shims can be used or is it as many as you like until you have ground clearance issues? I have a 1/4 inch (6mm) difference between length of right leg and left. Using 2 SPD cleats welded together on left side right now but this could be a really good option.

    I love Speedplay stuff but pedal strikes are a big enough problem with regular SPDs. I started using Speedplays on the road, for the clearance

    I’m stoked. I bought these pedal last year because I understood that these shims where in the pipeline. I currently have shims between the Syzr cleat and my shoe, and I have had the same result with this set up that I have had with the shimming of any mountain bike cleats – instability and unexpected release. The situation is so bad that I run road shoes and Speedily Zeros on my mountain bike whenever I want to ride aggressively. So I’ll take any decreased cornering clearance and potential pedal strikes that these things have to offer because it sure beats a face plant or a jacked up lower back from running without shims.

    This is fantastic, finally someone is producing a product to solve this problem. My wife has a 1cm shorter left lower leg after a compound tib-fib fracture many years ago. I’ve been buying flat pedals that I could rebuild on one side to add a 1cm spacer for her bikes, but she’s always been interested in trying a clipless pedal solution, and now someone is producing one we can just buy from a store. Happy day indeed.

      Hi, I too have the same injury your wife has with a 12mm (half inch) increase in my left leg. The recent solution was to add a solid orthopaedic spacer in my right shoe & release the laces on my riding shoes to attempt to balance the leg output. Numbness is the foot is a problem on long rides. After 25 plus years of mtbing this is the best solution I have found. Perhaps these pedals will work just as well.

    Is this only for leg length discrepancy or is it also possible to tilt the platform (varus/valgus) with different kind of shims? I certainly hope so. I need that.
