For a long time running, DX Flat pedals fulfilled the needs of the BMX and mountain biking market with a solid aluminum body, adjustable traction pins, and legendary Shimano serviceability. It's safe to say that pedal is a now a classic. Much has changed over the years, however, and the PD-MX80 Saint Pedals address the needs of modern riders and their tacky shoes.

One of those issues is with the traction pins. They are essentially set screws with a headless, internal Allen drive that's easily damaged by rocks and impacts, and then the Allen head would no longer be usable. For the PD-MX80 Saint Pedals, the pins screw in from the back of the platform.

This solved the dilemma of not being able to remove pins once damaged, but sacrifices one of the DX defining features -- adjustable pin height. Because the pins threaded into the body, you could thread them in to a height depending on traction needs. To work around this, Shimano includes washers with the PD-MX80s so you can lower pins where necessary and fine tune the pedals to your shoes and personal preference.

There are nine pins in total that thread into the low-profile alloy body. The new platform mirrors current market trends, placing your foot closer to the axle, and its large openings are optimized to shed mud. The Shimano PD-MX80 Saint Pedals feature durable chromoly axles and sealed cartridge bearings to ensure mountain biking strength for the park and shuttle run after shuttle run.

  • Solid alloy body absorbs park and DH abuse
  • Nine adjustable and replaceable traction pins
  • Open design for mud and debris clearance

Bearings are no good

  • Familiarity: I've put it through the wringer

I have two sets of these pedals, one for my wife's bike, and another for mine. After 30 rides their is significant play in the bearings. Pulling the pedal apart you can see how badly the bearings are made. The balls are held in place by a nut that keeps the hole assembly together. It looks like the pedal is designed to allow up and down play, as the bearings are only near the inner side of the pedal. The outside is a simple medal sleeve. After repeated use the sleeve appears to have worn down, allowing up and down play in the pedal.

Replacement axles are $23 each, the same cost as buying a new set on sale. If you want pedals without up and down play, then buy something else.

Great Pedals!

  • Familiarity: I've put it through the wringer

Great looking pedals that are super grippy once you remove the washers on each stud.
With the washers still in place, they're fine but much better for me without.

Great for bombing trails

  • Familiarity: I've put it through the wringer

I used to ride with clip-ins, but when I changed from hard tails to a Giant Trance SX, decided to give these a go. I wear 510 shoes, which have great grip, and never have any problems slipping off the pedals, and have found the advantage of being able to make slight adjustments of foot position on the fly to help change my stance on the bike. I use a dropper post on the bike, so constantly changing body position on the bike, but the Saints stay solid. Works well in the wet, as well as dry.

Shimano = quality fun

  • Familiarity: I've used it once or twice and have initial impressions

I ride clipped for the road, but when it comes to offroad, its always been flats. These are the first pair of platforms that i've had in which the pin height is adjustable. Pedals come with washers installed at base of pins, creating a very low profile spike. Remove the washers and you get a longer DH style pin height. I expect these pedals to be quality and last the length of my AM bike.

Best Platform Pedals

    Installed on my 2015 Diamondback Overdrive Comp which I mostly use for commuting and so far they've been great. No matter what I wear on my feet, the grip is always there! Highly recommended!!

    Put these on my wife's bike.

      Bought my wife a Giant Talon so she could get into some trail riding with me and put these on to replace the junk pedals that come with all bikes. She's ridden them a couple times and loves the feel of them. I'm positive these had saved her from slipping off the pedals a few times as she gets back into biking!


      • Familiarity: I've used it several times

      Very heavy duty design. No slippage (I use normal sneakers and had no problem). Lighter than I thought it would be.

      Shipped quickly.

      Burly Pedal

      • Familiarity: I've put it through the wringer

      These are solid pedals. Good grip with a flat sole shoe and they are pretty bombproof. Only downside is they are pretty heavy and thick, but awesome for the price.

      Great pedal, with the right shoes...

      • Familiarity: I've put it through the wringer

      I'm a fan of this pedal, but I just wish I could wear other shoes with it. I have to wear shoes with a flat sole in order to get a good grip on the little screws. When I do wear my flat soled shoes I really enjoy the ride, but it's not a good pedal if you want to ride and hike because you'd have to wear one pair of shoes for riding and another for hiking. Just a disadvantage of circumstance, but this keeps me from giving it 5 stars.


      • Familiarity: I've used it several times

      Replaced stock pedals on a Cannonade Quick CX4. Only have about 200 miles on them at this point but they have been a great purchase. They are much more durable than the stock pedals they replaced and have much more grip as well.

      I would highly recommend giving the Shimano pedals a try if you are in the market for replacement flat pedals.

      Not using any special shoes and the grip is sufficient for road use and I have not lengthen the pins either. They are quite no squeaking as mentioned by others and they are available here for a great price.

      Yep - what they said

      • Familiarity: I've put it through the wringer

      I use these on my Carbon Tallboy ... and bought a pair for my son to use on his Tallboy as well. Great grip - I removed the spacers from one side and left them in on the other - takes a bit of getting used to but the setup gives great grip in both dry and muddy conditions. No squeakiness at ll (vs. review below). a very solid and reliable choice that's at a nice price point

      Lookin pretty grizzly

      Get all the pins put in and all the spacers taken out and these pedals start to look pretty grizzly. This is my second pair (sold the first with my last bike) and I can already speak to their durability, and never had much problem with traction even without adding pins and removing spacers.

      Lookin pretty grizzly

      These are Great!

      • Familiarity: I've used it several times

      I bought these pedals after a bad crash with my clipless pedals last year hoping to 1. regain my confidence going over features so I didn't have to worry about being locked in, and 2. I had a desire to pursue endure/downhill more aggressively.

      I'm guessing if you are here looking at reviews of downhill pedals, you already know what you are getting into, but in case you don't, I think its worth mentioning that while the pedals "grip" well with my downhill flat shoes, you still aren't going to get the lift in your cadence that you would from a clipless setup. And you are going to want a flat pair of downhill shoes (not your running shoes) to make them worthwhile.

      That being said, I have no complaints with the pedals themselves. The traction pins are adjustable which is really nice. I've banged them on rocks and haven't had any integrity issues. They are definitely really nice to have for downhill (surprise!), but they are also decent for lower grade climbs. I also don't have any complaints with them feeling any heavier than my Shimano clips system.

      Great pedals for mountain biking!

      • Familiarity: I've put it through the wringer

      I wanted pedals that offered good grip but were not clipless. These met my needs. Great grip and extremely durable. I've beat them up on several trails and they still pedal like new. Customer service through Backcountry is unbeatable as well.

      My only gripe with these pedals is I still tend to lose my footing once in a while, I removed the spacing washers and it helped but I think my problem is a mix of the shoe I'm wearing and my novice experience. I'm sure it will improve over time. I would recommend these pedals.


      The shoe I was wearing had too deep of tread which was causing my feet to slip. I now wear flatter bottomed shoes and the grip is amazing. My feet actually stick to the pedals. Changing my rating from 4 to 5 stars!

      Great pedals for mountain biking!

      Great, adjustable grip, well made

      • Familiarity: I've used it several times

      I have been using these for a few weeks on a 29 and Fat bike. I love that you can adjust them in several ways as Sage (You are the Man!) mentioned. I find that out of the box and adding the 2 sets of additional screws is sufficient. They are very well made, very adjustable and have a nice curve to them that feels anatomically correct. Looking forward to using them this winter on the fat bike!

      Great, adjustable grip, well made

      Solid Pedal

      • Familiarity: I've used it several times

      I've been riding on this pedal for the last few months and found it to be grippy and durable. My feet have never slipped off. I've hit rocks with them several times with no damage other than minor scratches. I have not experienced any creaking. Overall, a great pedal.

      Garbage Pedal, worse customer service

      • Familiarity: I've used it once or twice and have initial impressions

      Installed these on my bike and at the end of my first day riding on them, they were already creaking. I was then told by and Shimano customer service to regrease them. Let's be honest, who wants to have to pack grease after one day of riding on brand new pedals? Very poor quality by Shimano and poor customer service by both companies. As a heads up, you will be asked to send your pedals back and you'll receive new ones with a 6-8 weeks. Hopefully you find a way to ride without your pedals for that long.

      Make sure to take the washers off if you want the true DH grip you'll need. That is one positive thing I've seen with the pedals is they are pretty good even with average shoes, but again, who wants to have to service their pedals right out of the box and then receive garbage for customer se

      good pedal, alternate the grip

      • Familiarity: I've used it several times

      Over all I rate this pedal as great, it s got solid construction, isnt too heavy, and has decent grip.

      as far as grip goes, in the low set up, I would rate them 3rd below the easton Flatboy, and the Twenty6 Predator. (which is so grippy its scary,)

      Adjusting the pins for more traction has the best balance and I favor this pedal due to its overall performance.

      Good Grip

      • Familiarity: I've put it through the wringer

      I have used these pedals quite a few times now and they are great. They provide more grip than my previous pedals that I have owned. They have 2 settings for grip on them, where as when you first get them they have the least amount of grip to them but if you need more you can always take out the washer and then it gives you about another 1/16 - 1/8" more grip. These are some durable pedals and will last you a long time, the only thing you might have to replace here and there are the studs which isn't bad.
