Best Overall Flat Pedal for Mountain Biking
Slim and slick
Robust axle yet low weight
20 grub screws per pedal
Customize easily with color options
Not a tight-budget option
Good but not best for downhill
From the first impression to last, the Deity Bladerunner
stole the show throughout our entire test period. The flashy purple anodized coating and incredibly thin 11 mm leading and trailing edges had us rushing to see if their performance could keep pace with their good looks. Though they proved to be a little less grippy than the Blackspire Robusto
or the Top Pick Race Face Atlas
, being able to make minor foot adjustments increased the versatility of this mountain bike flat pedal. Not only did it prove plenty capable for downhill or enduro use, but it was also equally at home on dirt jumps, freeriding, or in the bike park. Ten grub screw traction pins per side kept our feet just where we wanted them. The 11 mm pedal profile fattened to 14 mm at the axle, and a lack of traction pins in that area allowed some freedom of foot movement. Though this gave the platform itself a convex shape, the front and rear pins were made taller than the more central pins to give an overall foot cradling concave shape. While the Bladerunners were not the lightest of the test at 380 grams, they are still very light and plenty sturdy to hold up to the demands of any style of riding. Be prepared to have strangers ogling, as the coolness factor of these pedals is off the charts.

Best Bang for the Buck
VP Components VP-Vice
Solid axle and bottom-loading pins
No special tools necessary
Can feel axle underfoot
Not the grippiest
It was a heated battle with stiff competition. Honestly, we were surprised at our results with the ever-popular Spank Spike
and crankbrothers 5050 3
in the running. Ride after ride, however, it was impossible to deny our preference for this mountain bike flat pedal, the VP Components VP-Vice
ahead of it's nearest competitors. It was lighter than both the Spank and the crank brothers contenders. We felt the Vice's construction was superior, having experienced problems with both of the aforementioned pedals early into our test period. By contrast, we could have used these pedals as a hammer. The traction pins are bottom loading and protected from damaging pedal strikes, and there are four height adjustable grub screw pins around the axle that allow the rider to fine tune grip. The ability to micro-adjust our foot position while not feeling overly loosey-goosey on the pins made this pedal incredibly versatile. Adequate for downhill and enduro use, we could also maneuver about the platform while dirt jumping, freeriding, and when hitting bike park jumps. Rebuild is done with regular tools that you probably already own, and pin kits are available, although not included.

Top Pick for Enduro Racing
Race Face Atlas
Hardcore gripping power
Large and lightweight
Grease port tucked away
Super pricey and lack versatility
Not compatible with all cranks
The Race Face Atlas
took all the things we liked about various other mountain bike pedals and put them together into some sort of awesome Franken-pedal. Don't be mislead. This was not a slammed together, mishmash of random pieces, and the R&D team seemingly stopped at nothing shy of creating a masterpiece. Everything good was made better. "Concave? How about we make it double-concave? Are these traction pins grippy? Yeah, but they'd be grippier if we slanted them inwards. Hey, a hidden grease port would be pretty sweet. Let's add one of those." How in the heck was the biggest pedal in the test also just grams away from being the lightest? We'll leave the science to the engineers, but the fact is this pedal delivers with little weight, a huge platform, and insane grip.

Analysis and Test Results
To find the top performers in the market of flat pedals, we bought the best-rated and most popular ten models out there. Through three months of testing in California, Oregon, and Nevada, our expert testers pushed each pedal to its limit across a variety of mountain biking disciplines. Our riders installed, serviced, and removed the pedals countless times on different bikes to gain a full perspective of ability. On top of charging downhill, park jumping, and enduro racing, we carefully inspected each model in our lab. We scored our findings and experiences in five exclusive performance metrics, which, weighted appropriately, combined to give the overall score. Keep cruising below for a description of the metrics and to see which models ripped above par in each one.
This rating metric relates to the interface between the soles of our shoes and the pins and platforms of the pedals. Different type, number, and height of traction pins all combine to make each pedal feel unique. What felt good for dirt jumping could be terrifying on a rocky downhill trail. Some pedals like the Crankbrothers 5050 3 allowed the rider to adjust the height of the traction pins
by screwing them in further or backing them out. Other pedals like the Shimano Saint MX80
and Blackspire Robusto
used spacers to modify pin height.
Many had no adjustment like the RockBros Platform
, Bonmixc 9/16" 4 pcs
, and Funn Python
. In general, we found grub screw traction pins like those found on the Deity Bladerunner
and Crankbrothers 5050 3
to offer the best traction. It's not that simple though, as the mountain bike flat pedals with those types of pins were not necessarily the grippiest. Other factors like platform shape play a huge role in how a pedal feels. In fact, neither one of the pedals that scored highest in this category, the Race Face Atlas
or Blackspire Robusto
had grub screw pins.
The Shimano Saint (left) and Blackspire Robusto (right) were two of the more burly pedals in our test. However, with spacers installed on the Shimano pins, the grip couldn't hold a candle to the sole penetrating pins of the Robusto.
The long and thin pins on the Blackspire Robusto
dug deep into the soles of our shoes. The angled pins and concave platform of the Race Face Atlas
combined for max grip factor, while the broad pins of the RockBros Platinum
and Bonmixc 9/16"
pedals offered comparably less grip, seemingly too wide to effectively hang on to our soles. Like many things in life, balance is important. Pedals like the Spank Spike
and VP Components VP-Vice
had a good grip on things, but not so strong as to be suffocating. Unlike that distant aunt that sees you once a year on Christmas and clutches you too long, these pedals let you move about freely before things get awkward.
Good pedals must be supportive but not overbearing. A large platform provides a solid foundation for riders to push against, weight the bike in turns, and pump terrain features without slipping off the edge of the pedal. There's a limit though. Go too large and clearance quickly becomes an issue, as does leaning the bike deep into turns. Rocks, roots, and stumps all seem bigger as you continually smash your pedals into them. A thinner pedal can alleviate some of the risk but not all of it by offering increased clearance.
We particularly liked the Spank Spike
and thought it represented an impressive balance of surface area, thin profile, and impact avoiding (or minimizing) design features. The chamfered edges allowed the pedal to brush off impacts that sent the RockBros Platinum
into the recycle bin. A thin 12 mm profile gave the Spank Spike
the ability to swoop over, instead of straight into, rocks. The Race Face Atlas
shared a very similar platform shape but was a whopping 14 mm larger in width. With beveled edges, and a thin profile of 14.5 mm front and back, we experienced a slight uptick in pedal strikes; its meager weight (340 grams) and vice grip foot locking retention made it our preferred flat pedal for enduro racing and long technical rides.
The platform shapes clockwise from top left; Editors' Choice Deity Bladerunner, Top Pick Race Face Atlas, Funn Python, and Best Buy VP Vice.
The Deity Bladerunner
and Funn Python
had large square platform shapes. Shaving millimeters from the pedal profile was the preferred method for avoiding pedal strikes and it proved to be effective enough for us. Our Best Buy winning VP Components VP-Vice
had a comparably small platform, but bigger is not always better. Our lead tester loved how the smaller platform never got in the way of his big feet when performing tricks like can-cans that required him to remove and then replace his feet onto the pedals.
What we mean by pedal mobility is the rate and quality by which the pedal spins around its axle. Just like when your shifting is perfectly adjusted and you've tightened and tensioned everything so that all you hear are the sounds of nature and your friends hooting and hollering with excitement behind you, a smooth spinning pedal lets you concentrate on having fun instead of having to worry. Don't be confused into thinking that pedals that spin the easiest are the best in this category. Many cheaper pedals that come stock on bikes feel very loose and spin at a very rapid rate. Cheap bearings and bushings and poorly machined materials that don't mate together perfectly will do little to increase your confidence while riding.
Further, if you're performing freestyle tricks that involve taking your feet off the pedals, it's challenging to re-engage your feet onto pedals that spin freely when not weighted. Coming down on a pedal that is oriented vertically can be extremely dangerous. In essence, we preferred pedals that have smooth motion and spin at a moderate rate; ones where unweighting the pedal doesn't send them into a frenzy. Knowing that your pedals are correctly oriented when your foot wants to find its home on the platform is reassuring and much safer. Alas, the smoothest pedal from a mechanical quality standpoint in the test was easily the Blackspire Robusto
. The sealed bearings and proprietary KY bushings made the pedal feel frictionless as it spun around the nickel plated Chromoly axle.
However, the Blackspire Robusto
is a pedal that packs a lot of mass behind it with big toothy traction pins. While our feet felt glued to the pedals during use and we were very unlikely to slip off the platform, we felt the effortless spin of these pedals made them likely to dig into the back of our calves and shins or snag on our clothing when sitting on the bike or moving it around like when putting it onto our car's bike rack. It wasn't a huge problem, but when this pedal gets spinning, it looks like some sort of medieval weapon.
On the stiffer side of things was the RockBros Platform
. You won't get a full rotation out of these pedals with a hard hand spin, and our tester didn't feel comfortable taking these pedals through the jump line after a single lap. When the pedal got oriented vertically while kicking a foot off, it remained in that position throughout his flight. When he went to replace his foot, the firm nature of the pedal resisted and caused him come back to Earth with his foot on the leading edge of the pedal facing upwards. Not wanting to snap an ankle, he swapped pedals for the next in line.
Most other pedals in the test had similar rotation speeds, falling under the desirable "not too fast or not too slow" description. Regarding smoothness, second to the Blackspire Robusto
was the very high quality Race Face Atlas
. Much like with the Robusto, we rarely had problems with slipping off this pedal, as it was very grippy and the platform was massive. We also didn't find it to be an exceptional bike park or freestyle oriented pedal, so mobility wasn't as much of a factor for these. The rest of the lot spun at a nice rate, but a slight degree of resistance, graininess, or ratcheting could be felt. These qualities did not transmit from the pedals all the way through our shoes and could not be felt under normal riding conditions.
For the most part, mountain bike flat pedals are one of the few pieces of bicycle componentry that you shouldn't have to mess with too much. The Spank Spike
was the only pedal in our test that required attention as it started to make an annoying noise after only a couple rides. Upon taking it apart, we found the axle to be completely devoid of grease, or so we thought. Spank uses a new Finish Line Teflon grease that appears invisible.
Either way, our pedals needed attention very early on in the game, and although you'll need to service your pedals eventually, two rides into their lifespan was far too soon. We found the half plastic, half aluminum platform of the Crankbrothers 5050 3
to require an annoying extra step to access the axle nut and disassemble the pedal. Two long T25 torx bolts hold the halves together and must be removed. We weren't crazy about the material choice in the first place and the additional step to service the pedals didn't help to win us over.
Two T25 bolts hold the polycarbonate and aluminum halves snugly together. The pedal must be halved in order to remove the axle.
The hidden grease port feature on the Top Pick Race Face Atlas
performed well, although it did require a long-hosed grease gun which you may have to go hunt down at a hardware store — rebuild kits are available to remove the large inboard bearing. Our Best Buy Award-winning VP Components VP-Vice
pedals get top honors for this rating metric. VP went out of their way to make sure consumers can service their pedals without any bike specific tools. Even removing bearings can be done by tapping them out with a long Allen key instead of some specialized punch.
It didn't take long for one of our test pedals to develop a chirp. We opened it up and were very surprised to see the axle completely devoid of any grease. We slathered some on and things quieted down.
A lot of the guys crushing enduro races are coming from a more downhill oriented background. Forced to pedal uphill now, they are looking for ways to shave grams. The Blackspire Robustos
were the heaviest pedals in this test at 505 grams.
For downhill use, the Blackspire Robustos
are awesome. Add the Shimano Saint mX80 to that list at 490 grams
. They're another bombproof pedal, but one you might not want to spin for hours on end. We found the Top Pick Race Face Atlas
to offer the same superb grip as the Blackspire Robusto
at a fraction of the weight. At 340 grams, the Race Face Atlas
is an excellent choice for the enduro racer looking for a big platform and unshakeable grip in the lightest possible package. The Editors' Choice Award-winning Deity Bladerunner
was a bit less grippy, but more versatile than the Race Face Atlas
The Deity Bladerunner runner was a top performing flat pedal that can shave precious grams from your enduro race bike.
The Deity Bladerunner
was still only 380 grams per pair and had a very thin 12 mm profile, making it an excellent choice as an enduro or freeride pedal.
All too often many flat pedal riders give little regard to their pedal selection when in fact it should be a component worthy of much more consideration. As one of three contact areas with the bike, handling can be greatly diminished or improved depending on your pedal choice. For further advice, take another look over our Buying Advice
