Frequently asked questions answered by Steve Lubanski.

1. How much does the SMp weigh?

The ENTIRE system (both cleats and both pedals) is approximately 390 grams.

2. How much weight can the SMp support?

There is no rider weight limit. The cleat is designed to take 1,000 lb. load and is pronated 2 degrees, so it is physically impossible to flex outwards. You would probably have to take a cleat, put it in a vise, and flex it with a six foot long cheater bar to take it past 90º.

3. How does the SMp retain on lift?

The SMp uses an adjustable ball bearing detent to achieve its retention.

4. Can the SMp be used on a mountain bike?

Yes, but ONLY for road usage, i.e. commuting. However, there WILL BE a mountain bike version SMp in the future.

5. Is the SMp system difficult to install?

The cleats are NOT difficult to install, if the instructions are followed. Call us if you need assistance.

6. Doesn't the SMp increase the Q factor?

Some riders think because the pedal-engagement bracket protrudes from the inner edge of the shoe sole, the so-called Q factor (stance width) is fairly large. A shoe’s distance from the crank arm at the ball of the foot is 2 cm with the SMp and about 1 cm with the LOOK system. So there’s a substantial 2-cm increase in total stance width.

"This is true," says Steve Lubanski, "but it comes across as a negative. I strongly believe that human beings apply power down and out, and not down and in."

7. Won't my feet tilt to the outside during hard pedal strokes with the SMp because each shoe is supported on its pedal inboard of the sole? With conventional pedals, support is in the middle of the foot.

This is completely untrue! SMp's cleat is designed to take 1,000 lb. load and is pronated 2 degrees, so it is physically impossible to flex outwards!

8. How difficult is it to put the pedal onto the cleat when pushing off from a stationary position - looks like quite a small object to aim for when trying to cleat in?

It is quite easy actually as you can see what you are doing versus every other pedal system in the world, which must be done by feel.

9. On carbon cranks, if you don’t get it right, won’t the cleat do damage to a carbon crank arm?

The SMp system comes with small mylar strips to cover the crank arms until one becomes proficient using the SMp.

10. Do you have any demo SMp?

Yes, you can try the SMp out at Open Road Bicycle Shop in Pasadena, CA. Sorry, no demos out of state, currently.

11. Don't good runners land with their foot under their centre of gravity, very close to the centre line, effectively a Q-factor of only millimeters?

The first big advantage to the SMp system, is a wider Q factor. Contrary to popular belief, wider is better. Narrow Q factors make the bike work better, i.e. better chain line, stiffer bb, but they do not make the body work better on the bike.

Remember when you used toe clips and straps? You would every once in a while loosen the strap, and readjust your foot back inward. Biomechanically, the human body wants to apply power, from the waist down, in a down & out motion, not down & in; i.e., running, skating, etc.

Now of course, too wide can also be a problem, but Q factors have become so narrow and rear wheel spacing soo wide, that many people hit their heel on the chainstay during their pedal stroke, and go to systems with a lot of float to move laterally every pedal stroke. Thousands of strokes per hour, and they wonder why they have knee pain.

With the bikes of today, it is almost impossible to set your cleats, toe out, and not have to move your heel out during the back part of the stroke, except with the SMp.

The person who made the Q-factor such an issue, with a bike line named Bridgestone, now has another line, and these bikes have some of the widest Q-factors in the industry!

12. During very strong and frantic sprints and during those moments of "round" pedaling (type of pedaling where the bicyclist pulls upwardly with the pedal with the same effort as when he pushes downwardly with the other feet at the same time), it seems the SMp cleat that is pulling, would be violently disconnected from the pedal-crank and produce a crash.

This is where adjusting the bearing tension takes some time. To slowly adjust so it is tight enough in sprinting, but can be disengaged at a stop. A few track sprinters are currently using the SMp with success.

13. I'm wondering what the exact distance in millimeters is from the center of the axle to the top of the cleat platform? I'm trying to figure out if I'll be able to duplicate my exact stem height, relative to my saddle, after lowering my saddle to compensate for use with the SMps.

The top of the cleat is actually below the center of the axle spindle by approximately 1 cm. If you ride LOOK pedals, you will lower your seat/stem height by approximately 4 cm.

14. Will there be an adapter available to use the SMp with normal
street shoes?

Yes, in the future there will be...

15. I'm extremely interested in the SMp, but am not sure if I can use them with winter booties.

Yes, just slit a hole in the side of the bootie.

16 . Time will tell if you're one more scam-arama sucking $ out of consumers and investors. But with that much invested in your show display and web site, and not a single word on whether your pedal retains on lift (like the straps/cleats and LOOK pedals you compare it to), you're at least devious...if not dishonest.

What could we possibly say to such a comment?
Let's let Mr. Bridgman speak for us:

"There is no adequate defense,
except stupidity,
against the impact of a new idea."


Percy Williams Bridgman
(1882-1961)

Bridgman was an American physicist
who won the 1946 Nobel Prize in Physics
for his work on the physics of high pressures.
