eh and the whole lower center of gravity thing is BS too......... all pedals attach to the bike at the same point. Yeah your body might be 10mm lower (but hey, crouching lowers your body by 300+mm), but you weight distribution on the bike will not be effected at all, becuase pedal will always attach to same point.----->
Dont really want to look up what #reason that is.

I like them, but benefits #2 and #8 are bogus
#3 You are not going to get more ground clearance out of those because (Due to the design) the pedal arm will always have to protrude downwards another 10mm. For sure increased clearance on outer edge of pedal, but thats not what I (or anyone else) is afraid of when you are mashing those pedals on a DH run.
#8 You are saving 40g on a rotating object with a a radius of 340mm. Compute that..... essentially saving 3 g on your wheelset has the same difference. Ever notice how hard it is to pedal when a tiny rock gets stuck in your tread? I thought not.
Problem #1
-Looks like you need to modify your crank arm and have special tools to accomodate the pedal. Big money big money?
Conlusion: I really dig the design, and like these pedals. However, I hate super hype marketing. The design speaks for itself-- if you make it, everyone is going to want to buy it. Dont over hype it! I personally can't wait to try a pair out.

Mud issues, you ask? That's what the swiss cheese holes do, is allow mud to squish through, so that your foot will engage the traction pins. I did a couple of rides this summer where we got caught out during the monsoon rains here in Sedona. Torrential downpour. Thick, sticky clay. Pedals worked well. No problems with foot slippage!

Well, at 405 grams the prototype is not the lightest pedal.DMR Mag w/ Ti axles weigh under 400g, for example.And those aren't the only sub 400g flats on the market...

Frequently Asked Questions about FlyPaper pedals:
Q. They're so thin! Aren't they going to be flexy or bend or break easily?
A. Take a close look at Azonic A-Frames, Tioga MX Pro's, Wellgo B27's and B 54"s and the Xpedo pedals, and you will see thatalthough they all have two layers, both layers are very thin, and all of these pedals have HUGE cut-outs in both layers. Now look at some Crank Brothers 50/50 pedals. They are also very thin, with huge cut-outs, but only one side of their design is really structural...the other side is semi-structural at best! FlyPaper Pedals Have about the same amount of structural material as many of the above mentioned pedals, I've just eliminated the redundancy and non-structural B.S. found on all others!!!
I weigh 200 lbs, live and ride in Sedona, AZ, some of the rockiest, gnarliest technical terrain on the planet. I do jumps, drops, brutal climbs and crash frequently on slick rock. I have also made two trips to the Zion area in Southern Utah (Gooseberry Mesa, Little Creek Mountain, Flying Monkey, etc.) two trips to Boulder City and a trip to Oregon and Northern California to thrash test these puppies. So far, they've handled everything thrown their way with flying colors, and have actually exceded my original expectations in performance!!! As for impact, to test durability, I actually try to hit them on rocks to test them. Most often, I miss the rock I'm aiming for because they're SO THIN. In fact, I hit the bottom of my shoe several times for every one time I actually manage to clip my pedals on a rock!!! However I have succeded on several occasions and have plenty of rock induced gouges to prove it!
Oh yeah, if you place your foot on the outer edge of a FlyPaper Pedal and push down as hard as possible, you can see the crank arm flex in about 3/8 of an inch, the frame also flexes a small amount, but there is no discernable flex in the pedal!!!
Q. The bearings are un-supported, won't they blow up quickly?
A. Once again, I weigh 200 lbs and ride some of the most rugged terrain on the planet. (Look up the trail reviews for The Flying Monkey, a trail I built) These prototypes have seperately machined bearing cups attached to a modified crank arm. Trying to mate three seperate machined pieces resulted in bearing cups being mis-aligned by about 2 thousandths of an inch on the right crank arm and one and a half thousandths of an inch on the left crank arm. This doesn't sound like much but because of how close the inner and outer bearings sit to each other, and the high tolerance that they are manufactured to, there was initially a small amount of binding noticeable when spinning the pedals by hand. Additionally, the inside diameter of both inner bearing cups is about two tenthousandths of an inch too tight on one cup and four tenthousandths of an inch too tight on the other. Since this is the DIAMETER, one cup would ideally need one tenthousandth of an inch taken off the RADIUS, and the other would need two tenthousandths removed. It is very difficult to remove this small of an amount of materila in one machining pass, and quite time consuming to try to sand it off, so we opted to leave it on the prototypes. On the production model, with the bearing cups an integral part of the crank arm, perfect bearing alignment should be no problem, and the depth setting on the final cut should be spot-on, as well.
All of that being said, it took about three months worth of wear to get the bearings to "break in" and for the pedals to actually spin freely by hand. As far as riding, even at their tightest, there was never a noticeable detrimental effect when riding them. At the rate that they are wearing, I'm estimating the bearing life to be somewhere around three years. (And that's with the prototyping problems I mentioned above, which if anything, will shorten the bearing life of this pair.) When I ran Atomlabs Aircorp pedals, I was lucky to get six months out of a pair of bearings, and then they usually failed catastrophically, with no warning, miles from nowhere. With the much larger size of bearings used in FlyPaper Pedals, the bearings should wear out gradually, rather than failing catastrophically.

EVEN MORE BENEFITS!!!
7. Lighter weight... The protoype shown in this photo uses steel bearing cups and weighs in at 405 grams over what the stock crankset weighed without pedals. The production version will have the bearing cups machined or forged right into the aluminum crank arm and will certainly come in at under 360 grams, perhaps even approaching 300 grams...
Not only is this rotating weight, but some of the most outward rotating weight on the entire bike, getting more leverage on you than anything but the tire, tube, rim, spoke nipples and part of the spokes!
8. Benefit #7 increases benefit #5!!!

MORE BENEFITS...
4. Increased stability... the THICKER a platform pedal is, the more UN-stable it is. this is easy to illustrate with a spare set of pedals and a zip tie or two. Zip tie both of the spare pedals to ONE of the pedals on your bike, one on top, the other on the bottom. Now go ride up a hill. Be careful though, because when you stand up on the triple-thick pedal you just created. it will want to roll under your foot so badly that you might just rack yourself on the top tube...
So... if thicker is less stable, thinner is obviously MORE STABLE! This means that you can start pedaling earlier in the pedal's rotation, and keep pedaling later, pushing harder across the top and bottom of the pedal stroke than any other pedal!
Which bring us to our next two benefits of FlyPaper Pedals...
5. Increased power for climbing and sprinting...being able to push and pull across the top and bottom of the pedal stroke harder than on any other platform pedal makes FlyPaper pedals perform closer to clip-in pedals than any other platform pedals!
6. Smoother, more controllable power... with both ends of the power stroke significantly extended, power delivery becomes smoother, more continuous and less "spikey", helping to keep you from overpowering and spinning the tire, thus allowing you the ability to maintain traction and forward momentum on loose, steep climbs, in slippery mud and other low-traction conditions

O.K. now for some long awaited info / answers...
I call these "FlyPaper Pedals" because they,re thin and STICKY! Most platform pedals are around 24 to 25 millimeters thick, (not including pin height), while some are as thick as 27 millimeters. Prior to FlyPaper Pedals, the thinnest platforms I am aware of were 17 millimeters thick. FlyPaper Pedals measure a mere 3.7 millimeters THIN!!!
Advantages:
1. Larger, more durable bearings...the scrawny bearings (and bushings) used in most other pedals can drop right through the center of the bearings used in FlyPaper Pedals!
2. Lower rider platform... with FlyPaper Pedals more than 20 millimeters thinner than most platform pedals, the rider,s platform is 10 millimeters lower. That means 10 mm lower saddle height, 10 mm lower handlebar height and 1o millimeters LOWER CENTER OF GRAVITY!!! Think faster, more stable cornering, steeper descents to squarer hits at the bottom without endoing and being able to climb steeper things before the bike tries to wheelie over backwards!
3. Increased ground clearance... that same 10 millimeters of extra thinness is also on the bottom. Now you can pedal through more rock gardens than ever before!
What's that... you said that your bike already had enough ground clearance designed into the frame? Then RE-DESIGN your frame with a 10mm LOWER BOTTOM BRACKET and get a 20 millimeter lower center of gravity!!!

Look closer. It looks like the spindle is attached to the pedal body, and then the bearings sit on either side of the crank arm. That seems like it could work. I like it.
What looks heavy about those? They're so much thinner than anything else- that's less volume, and therefore less material ---> less weight.

It just seems like it would be very flimsy. The spindle doesn't run out to the edge of the pedal which would typically provide a lot of stiffness. Bearings without support on both ends do not last, period.

It's only weird because it's not normal.

It's not heavy at all. It's ridiculously light. I believe Dean said it's lighter than any other flat pedal currently available. And there are a whole bunch of technical reasons why it should perform better than other pedals. But I'll let Dean or someone else tell us about it more.
