Shimano and Crankbrothers are the first to come to most people's minds when thinking about clipless pedals, with companies like Time, HT, VP, and likely to a lesser extent, Speedplay; the latter not as prevalent as they once were when their Frog pedals were a more common sight. The SYZR pedal is their new-ish option designed for mountain biking, and while it's been around for awhile now, the company has updated the SYZR to offer an aftermarket stackable body, called the 'Leg Length Discrepancy Kit,' that allows riders to adjust pedal body height, and therefore how high your shoe sits above the spindle when you're clipped in.

SYZR Pedal Details

• Intended use: mountain biking
• Ceramic roller cam mechanism
• 10-degree, micro-adjustable float
• Composite body
• Adjustable pedal body height
• Weight: 275 grams (pair, titanium spindles)

Speedplay's proprietary clip mechanism is screwed down onto the pedal's composite body, but should you want to raise that mechanism up, spacers can be installed in between the two halves of the LLDK pedal body kit. And since the clip mechanism is screwed down onto the body, it thereby raises it up and away from the pedal spindle. You can stack up a load of spacers if you wanted to - Speedplay had one pedal on display that was at least twice as thick as the stock setup - although I suspect that ground clearance would become a real issue at some point.

I bet I know what you're thinking: ''Why the hell would I want taller pedals?'' That's the same question that popped into my head mid-eye roll while I was standing in front of the Speedplay booth, but it could serve a purpose for some people. I'm friends with more than a few riders who, because of some sort of serious injury, have one leg that's significantly shorter than the other. Those who have real issues would usually wear some type of custom shoes in their day to day life that sport different sole heights, but it's not that easy when it comes to cycling kicks.

Or maybe it is if you were using the SYZR pedal.

They employ an odd looking cleat that bolts to a standard two-hole SPD mount, and you adjust float via tiny screws that act as limit screws on the cleats themselves. The SYZR pedal is available in three flavors: with titanium spindles that weigh in at 275 grams for a pair; stainless steel spindles that weigh 312 grams for a pair; or the 338 gram chromoly spindle option.

 Might as well use all 4 sides when it gets to the point that the thing is a cube...

Leg length discrepancy (LLD) is actually more common (majority) in the general population than not. We are all asymmetrical to various degrees. The degree of LLD is important as small LLD may not require correction.

When walking or running the pelvis and feet are not fixed in space so can deal with asymmetry, if you observe wear patterns on your running sneakers you will see a telling clue to how you operate.

When on the bike you (asymmetrical) are fixed at foot and pedal, and bike is symmetrical - you often see effects of LLD on pelvic rotation and unstable pedalling stroke.

This difference can be structural or functional but is treated the same way in bike fitting on road bikes typically using 3-bolt pedal system with LLD shims between shoe and cleat, or varus wedges stacked in opposing group

However, this does not work as well in MTB as the common SPD system relies on contact between shoe and pedal - as you stack LLD shims the pedal loses contact with shoe and the SPD becomes unstable.

The old difficult method was stacking pontoons often requiring cutting and bonding to match the new cleat height.

This new SYZR looks like very smart thinking

cheers and happy trails!!

 You, sir, know what you're talking about. I fall into the "severe injury, shorter leg" category and while I don't notice it as much mountain biking because I'm often out of the saddle it's a big issue on the road bike.

 Well said and at last I'll pedal with equal power from my legs.

 I have a significant leg length discrepency (just over an inch) and have made adjustments to my road bike, but for the reasons you described couldn't adjust the mountain bike.

All of my seats have collapsed on the side with the shorter length, from my hips reaching down.

This product is super interesting.

 Wouldn't custom shoes be a better solution? Portable between bikes, and without the downside of increased pedal strike that these have.
  • 2 0
 @dsut4392: custom shoes would be significantly more expensive, you also need a pair of pedals for each bike regardless. On mtb you also want to be able to walk in your shoes, a generic solution to shoes would make this very challenging

 Ow, nice !
I have a 15mm discrepancy, for no particular reason.
For the last 3 years I kept having knee pain everytime I tried to ride a bit more regularly, until a physiotherapist found out the knee of the longer leg has a tendancy to stick outward a bit at every pedal cycle.
Since then I've been using 2 different pedals (xpedo flats, 11 et 20mm thick), but as I would have needed a 30mm pedal I also switched one of the crank so one is 175mm and the other 170mm, so while the difference is 10mm when the short leg is low and 0mm when it's high, the joint angles are similar.
The therapist said the torque difference shouldn't be a problem.
Since then most pain has disapeared and I've been able to ride regularly and much harder, also the pelvis is more stable and has much less tensions. Doing stretching regularly too.

 I used to use Frogs (and before that, Magnums) back in the day. They were great. But it would be hard to imagine switching off XTR Trails at this point. I'm glad to see they're still innovating. That pedal height adjustment thing is cool.
  • 1 0
 I actually did. happy user of xtr and my lbs guy kept praising this pedals. I made the dumb mistake of believing in him (he is a roadie) and bought them. 3 rides later they were out. sure this are miles ahead of xtr when it comes to mud cause lets be honest shimano really needs to step it up there, BUT sucked evrywhere else. I really think the devil you know better than the devil you dont apllies perfectly for pedals. I know exactly what my xtr are going to do, the zyzr were just unreliable.

 closed minds don't fix anything, embrace the idea and realise the benefits, this industry has too many youtube experts, I have been thinking of new pedal ideas for years and have an addition to this idea i think people will be interested in, this may be a master stroke...well played

 Building up the pedal body instead of under the cleat is a fantastic idea. And on an mtb pedal to boot. I have an assortment of home made shims in various thicknesses and very expensive stainless steel cleat bolts in various lengths (that do not come in the appropriate alan key size for this torque application) for my short leg. The Syzr is a great solution. You have to purchase the shorter axles, though, if you want q-fatcor to be on par with Shimano.

 And stacking a cleat is only needed for a tibial LLD. Far less common than a femoral discrepancy. So cool for that I guess but it's a product that only provides a benefit to a very small population of end users. Cause there's literally no others

 unless they cost $1000, I'm not interested

 Great news! I'll happily sell you a set for $1000. Just make out your money order to Prince of Nigeria and my barrister will pick it up at your place of business, and I'll ship the pedals as soon as payment is tendered. Trust me.

 @pinhead907: No problem - the issue is I work on an oil rig off shore, if I send it COD can you just mail them to me if I arrange the courier. These will be a gift for my son

 We have a customer at our shop who had cut get his crank arm cut and welded back on with a chunk taken out to make it 142.5 on one side and 170 on the other to do basically the same thing as these pedals
  • 1 0
 No, it's not. The lever arm of the crank will change at 12, 3 and 6 o'clock with the thicker pedal body. Your customer might need a 142.5 crank at 6 o'clock for a short leg. but then the lever is also that much shorter at the power phase, 3-5 o'clock.

 @trundle: Indeed, I've done some 3D simulation for my LLD (15mm on the left femora) and it's pretty tricky to find what's best.
In my case I "decided" it might be better if I could keep both of my legs' joints (hips, knees and ankles) work at a similar range of motion rather than go for a strict length correction, so I have asymetrical pedals and cranks, as a shorter crank + thicker pedal seem to draw a "better" trajectory than just a much thicker pedal (or a much shorter crank).
At 6 o'clock, when the leg stretches and the LLD is the bigger the left foot is 10mm higher than the right, but at 12 o'clock, when the calf is nigh horizontal and the LLD not that important, the shorter crank attenuates the thicker pedal. At 3 and 9 o'clock it's somewhere in between.
It doesn't work that well if I'm standing on the pedals though.
But so far it's working.

It's also different if the LLD is on the femora or tibia.

 Kudos to Speedplay for offering a product that will be appreciated by those who need it. Looks like a more complete, less compromised solution that shimming cleats or stuffing inserts in the bottom of your shoe.

 how many different mtb pedal designs has speedplay come up with? where are they now?
  • 1 0
 Surely a modified cleat or shoe sole would prove far more effective than this. Having a deep from centre line pedal is far more likely to cause an injury than prevent one!

 Wish I could blame my slowbro problems on LLD...I'm just slow and like beer!

 A leg length difference can cause tremendous back pain. This solution is not all about performance/speed.

 Those height spacers are just another source of creeping on a bike.. should be monoblock!

 Now if we could only get someone in the "industry" to realize not everyone who rides can shift with their right hand.

 Why don't they just put washers under the cleats on their shoes?...
  • 5 0
 Because then you'd have a massive cleat shaped spike sticking out your sole and wouldn't be able to walk..

 @Daver27: But they aren't walking, they're cycling haha

 because mtb shoes use the sole's tread lugs to provide a platform on the pedal
