Kneesavers and Eggbeater pedal systems

Hi-

I recently bought a pair of Scor Kneesavers Pedal Adaptors(standard 20mm size) to work in tandem with my Crank Bros. Mallet C platform pedals with the Eggbeater cleat system. To my dismay, it doesn't look like they're going to work together. Crank Bros.' Eggbeater pedal systems do not get tightened down into the crankarm by using a standard pedal wrench. They're tightened down by using a 6mm allen wrench, approaching the pedal from the opposite side of the crankarm "hole". And because the Kneesavers are solid, once they're screwed into the crankarm, you can't get through them to access the pedal spindle with the allen wrench.

Has anyone here had the same experience, and are there any solutions to this? I'd love to be able to use these Kneesavers, but it looks like I'll have to lose the pedals and get another pedal system to do so....



Thanks ahead of time for any help!

It sounds like the Kneesaver is just a spacer that sets the pedal further away from the center line of the bike, eh? And it also sounds like the part of the pedal axle that faces against the crank arm has no "flats" for an open-end wrench. A few things come to mind. One, you could thread the kneesavers onto the pedals first, and just use a vise-grip or the like to hold the axle. Then put the assemby (I assume the Kneesavers DO have flats on them) into the crank arm. Or, if the kneesaver is strong enough, you could drill a hole in the middle of each, big enough to expose the allen hole in the pedal axle. Finally, could you possibly adjust the cleat that goes with the eggbeater system so that your shoe is far enough away from the center line, obviating the kneesaver altogether?

Hi madpogue,

Thanks for the suggestions! I've emailed Scor, the makers of the Kneesavers, and they were very prompt in getting back with me. I'm mechanically challenged, but I think I understood their explanation(s). Let me see if I can adequately respond to your suggestions, Paul....

First, yes, Kneesavers are basically spacers that offset the pedals further away from the crankarms(your reference to the centerline is probably more relevant, madpogue). They are available in different widths, but their most common size is 20mm. They are beautifully machined from stainless steel(also available in titanium for more "$monium$")...very robust and well built...and they do have "flats" on them, allowing them to be tightened down with a standard pedal wrench(just like the "flats" on most pedal systems---but not on the Eggbeaters system by Crank Bros.).

You could screw the Eggbeater pedal into the Kneesavers first, and then screw the assembled pair into the crankarm...you'd be able to torque the Kneesaver threaded end into the crankarm well enough...but you wouldn't be able to torque down the pedal securely enough into the Kneesavers....unless your initial "torque-ing" using the visegrips can really get them snugged in...and even then, I'm not sure if the pedals will stay tightened down into the Kneesavers....

As far as drilling a hole to create the hollow needed to get the allen wrench through the Kneesavers to access the pedal axle...Scor told me that any kind of drilling will adversely affect the Kneesaver's structural integrity....so it's highly discouraged....

The Eggbeater cleat is about the same size as a Shimano mtn cleat, and a little more robust. It pretty much fills up the cleat space(the width of the space) on the shoe...since it screws into the two holes provided for a typical spd cleat, you can't really move the cleat more to the side...and even if you could, the cleat(and therefore the pedal) would then be placed off center to the ball(or just below the ball) of your foot...which could adversely affect pedaling efficiency and promote muscle fatigue in that area after or during a long ride....

It's really beginning to sound like I'll hafta sell these two pairs of Mallets(one pair of "C"'s for the Fusion, and one pair of the new lighter magnesium "M"'s for the GTO trike).. and get a pedal wrench-friendly pedal system to replace them if I plan on using these Kneesavers to increase my "Q factor", whatever that is(something to do with improving pedaling efficiency...increased comfort and decreased possible pain and discomfort to knees and possibly hips...helping support those who tend to walk/pedal "toe-out", or who have wide hips....am I right?)

If I do end up replacing the Mallets, then can anyone recommend a good pedal wrench-friendly pedal system as their replacements....I'm thinking possibly Speedplay Frogs or BeBops...any thoughts or opinions would be greatly appreciated...thanks!

I dont think you have to get the pedals screwed tight into the kneesaver so madpogue's suggestion of using visegrips or pliers is good. The pedalling action tends to keep the pedals screwed in - thats why the LH pedal is reverse threaded. Then use the pedal wrench to screw the kneesaver into the crank.

Hi AndrewP,

Well, just for fun(and to see how it might work), I tried hand-screwing the Mallet C into the Kneesaver. It went freely for about 2 revolutions...and then didn't want to go any further. I tried doing this 2 more times, and experienced the same brick wall resistance. I think this must have something to do with the allen hole inside...that you need to use the allen wrench to complete the "screwing in" of the pedal.

I guess I'm just going to have to decide whether it's more important to keep the Kneesavers(and the benefits they offer) and find another pedal set that'll work with them...or return the Kneesavers and keep the Mallets....


Thanks for your comments and help!
