Review: Burgtec's New MK4 Composite Flat Pedals

Burgtec MK4 Composite review

Burgtec's original Penthouse flat pedals were born and bred in the UK, where they gained something of a cult following due to their ability to take a beating and keep on spinning, as well as survive the infamous rainy weather. The lighter and thinner MK4 model came out a few years ago, and now Burgtec has added a composite version to their lineup.

The new MK4 Composite pedals share the same shape as their aluminum bodied sibling, with a 104 x 105mm body, a chromoly axle, and 8 replaceable pins on each side. They're ever-so-slightly concave, but the lack of center pins helps make them feel even more concave than they actually are. The pedals retail for $55 USD, and are available in a wide array of colors, including red, blue, purple, bronze, and orange.

MK4 Composite Details
• 8 pins on each side
• Platform dimensions: 104 x 105mm
• 18mm thick
• Fiberglass / nylon platform, chromoly spindle
• Internals: cartridge bearing, bushing
• 8 color options
• Weight: 379 grams
• MSRP: £39.99 / $55 USD

Eight pins provide a good amount of traction.

The pedals spin on a chromoly axle, and use a cartridge bearing / bushing design.

Burgtec MK4 Composite review
The plastic body has a collection of battle scars from the last couple month of riding, but the pedals are still spinning smoothly and all of the pins are in place, although some aren't quite as straight as they once were.


The MK4 Composite's platform is a little smaller than the spec sheet suggests – the 104 x 105mm measurements refer to the pedal's overall dimensions; the actual platform your foot will be resting on measures 104 mm wide x 97mm long. These aren't a supersized option like what's available from Kona and Deity; they have a more traditional profile, along the lines of a DMR Vault or ANVL Tilt.

In any case, although they don't have the biggest platform, the MK4's were still comfortable and had plenty of grip for keeping my size 11 feet securely in place. The pins are relatively skinny, which helps them really dig into the sole of a shoe. Compared to the ANVL Tilt pedals I was on prior to these, the MK4's were slightly less grippy, but it was also easier to re-position my foot when I wanted to.

Over the last couple of months the MK4's have been smashed into plenty of rocks and roots, and they have the battle scars to prove it. That's one of the downsides of plastic pedals – they tend to get scuffed and beat up more quickly than aluminum bodied options, although I can't say I spend much time fussing over how my pedals look. The pins are all in place, although a couple now have a drunken lean after getting pummeled into a rock or ten. They thread into a nut that's pressed into the pedal body, and pin replacement is on par with the vast majority of flat pedals out there – the level of difficulty totally depends on how mangled the pin is.

The MK4's spin on a cartridge bearing and a bushing, and so far are still rotating smoothly and are free of any play. I pulled the axle to check on the internals, and was happy to see that there was a generous amount of grease applied from the factory.

Pinkbike's Take
bigquotesBurgtec's MK4 Composite pedals provide all the traction and stability of their aluminum counterparts at a fraction of price – it's hard to argue with that. They're not the widest or absolute grippiest option on the market, but they strike a very nice balance, with a shape that should work well for a wide range of riders.  Mike Kazimer

 Like the look of these, they seem to have an extra 5mm or so of additional offset from the crank arm too which solves one of the only things that niggle me about the alloy version, the bodies run so close to the arm.

 You can buy the longer axle version mate.

 @BradHolland: Didnt know that, had my pair for a while now ,will have a look.

 @justanotherusername: Just search for Boost axle set. A gentle upgrade that gives you additional 5mm.

 @tworldsmine: is that just the axel or can you buy the pedals with normal sized axels?

 M4 pins please!!!

While M3 pins work i much prefer the feel of M4 pins of DMR Vaults, more grip and less rip...

Is there any plastig pedal out there with stock M4 pins?

 That's my one gripe of composite pedals.. I really dig the One Up pedals, but would prefer an m4 Screw. I'm guessing the M4 nut being bigger and heavier, tips the scales too much, when multiplied by 14 per pedal, 28 per set.

 @shrockie: I am considering re-pinning to M4 using some kind of bonding agent and some custom mild steel washer the hard screws can self cut a tread or two. Wont be replaceable but with ok price on plastic pedals I dont care.

 @feeblesmith: Look for M4 Threaded inserts.. they may fit the M3 nut hole.. Then melt them into place.. The nut will have better strength to rock strikes though.

 I'm going to say this again, but squared-off leading edges on pedals are ridiculous. You don't have to be an engineer to realize they'll hang up on a root or rock instead of skip over like beveled leading edges.

 @tripleultrasuperboostplusplus But you are an engineer, right?
  • 2 1
 They aren't squared off leading edges. They're squared off trailing edges from the other side of the pedal. Duh.

 Cheap light strong. Pick three. Explains why I have plenty of plastic pedals. Been using them for over a year. No annodizing or paint to wear off. When the bearings wear out I'll buy new pedals.

 Same, i'm running the Nukeproof Electron Evo plastics on more than one bike and cant fault them

 I find them great on FR/DH bikes but they do not spin freely enough for any long distance stuff. Ive had 4 sets the last year and they all go back on the FR/DJ/DH bikes. . They are much stronger than other pedals. So pros and cons.

 Interesting comment on the strength - I’ve seen a couple of burgtec axles snap!

 @Gareth-R: I l snapped a ti axle. Both were replaced foc without question. I opted for the regular axles second time around which served me well. I'd buy again but with the boost axles this time.

 @Gareth-R: was it due to an A bomb?
I've had lots of sets and They've been mint. I'm a pedal killer for some reason and they have been the best.

 One was on a drop (not to flat). Can't recall the exact circumstances of the other one. Both were a couple of years ago now so maybe they've changed. I did snap a correctly torqued stem cap myself whilst riding round a car park - possibly lots of bad luck but it put me off Burgtec overall.

 Speaking as a guy with big feet, theses are nice enough compared to some. BUT...Deity T-Macs are still the absolute BEST overall pedal out there. Yes I’ve tried the vast majority of the larger pedals.
  • 5 0
 You ever tried the Kona wah wahs?
  • 2 0
 @JikkityJek: yes, they’re just ok at best.
I’m also not a fan of the larger inboard bearings, big bolster gets in the way for me.

 I really like composite pedals, they're durable, great price point, offer great grip and weighing in at only 1 Big Mac, what's not to like?
  • 2 0
 The looks.

 That assumes that anyone who clones them other than the OEM who makes them would get the composite/blend right for the body, 5% glass fill, 10% ? And it also assumes that people are happy buying knock-off Chinese products that f*ck over their favourite brand.

 Scudgood pedals S14 shipped. You are welcome
  • 1 0
 This may become a real problem for any manufacturer - as chinese knockoffs are being shipped from within EU and not 20days plus tax from Chenzhen anymore..
Kona Wahwah or RF Chester clones look exactly the same for 15 - 20€ shipped. Will not take long for a Burgtec clone.

 @cxfahrer: you every consider that they are not Chinese knock off? They're likely made in China for the big brand. I've had a couple sets of Deity's and they're great, but I've also had a couple sets of "knock off" and they're identical save less sanding on pedal body. I think supporting a brand name is great, but I also think brands that make things are cooler than brands that order things from the catalog.

 Could it be the same manufacturer at a fraction of the price because no fancy name?

 I'm waiting for a pair to turn up in the post, I went for purple rain and I'm hoping that they are as pink as they look on their website!

 Lightish, but not quite as light as i would have hoped with plastic pedals.

 If you want the absolute lightest composite pedals with different sizes for the shoe sizes, the Crank Brothers Stamp 1 weighs in at about 300g for the small size, which still has a pretty wide platform. I was actually gonna get the OneUp composite pedals, but the CrankBros Stamp 1 was about $20-25 cheaper with a 5 year warranty - no others can beat that!
