Crankbrothers has revised the Stamp 1, their most budget-friendly flat pedal, retailing at £59.99. Whereas the composite platform form is up to date to ship the upmarket look of the aluminum Stamp 7, the platform dimensions are unchanged.
There are two variations of the Crankbrothers Stamp 1 Pedal:
- The Stamp 1 Small (examined right here) measures 100mm x 100mm, advisable for EU Sizes 35-43.5 (US 3-10, and UK 2-9)
- The Stamp 1 Giant measures 111mm large, and 114mm lengthy, advisable for EU Sizes 43.5-49 (US 10-15, and UK 9-12+)
Extra essential modifications come on the within, with a chromoly metal spindle and low friction IGUS bushings, and an upgraded seal system that can also be seen on the dearer Stamp 7 pedals. The bushings are stated to be extremely proof against put on, whereas providing a low coefficient of friction such that the pedal will proceed to spin freely in a variety of hostile situations.
The updates are stated to forestall water and particles from coming into the pedal, extending its usable lifetime. When the bushings do finally put on, they’re simply changed with the acquisition of the Stamp 1 refresh equipment – at a value of £23.99 ($24.99 USD).
I’m as much as round 25 rides on these now – right here’s how i’ve been getting on with them.

Crankbrothers Stamp 1 Pedal | Evaluate
As a wearer of UK Dimension 4.5/5 footwear, I examined the Crankbrothers Stamp 1 Small pedal. All through the two-month take a look at interval, I paired them with each the FiveTen Freerider and the FiveTen Trailcross XT footwear.
Any pedal is just pretty much as good because the shoe it’s paired with. And, i’m comfortable to report that each pairings have been superb. Pushed to say which is best, i’d give the Freerider footwear the sting. The improved connection is probably going owing to the worn-in Freerider shoe being that little bit broader, and extra versatile.

The Stamp 1 pedals are 15.5mm thick on the main/trailing edges, and the 13.5mm thick within the central area. There’s a very delicate concavity throughout the platform of simply 1mm. I can’t simply discern that on the path, although.
Pedals with an exaggerated concavity can enable your foot to flex right into a form of claw-like form, along with your toes curled over the entrance edge barely – shoe sole flex-dependent. Whereas it doesn’t sound preferrred, it might probably truly present a really safe locked-in really feel, however it might probably additionally result in foot fatigue.
Given the nice grip i’ve skilled with the Stamp 1 pedals, i’m inclined to say that Crankbrothers have discovered a superb stability with the delicate concavity. It’s sufficient that I can really feel the pedal has some form to it, giving good consciousness of foot place at any given second. However, I discover my ft are properly relaxed, with out sinking deep into the mid-section.
The Stamp 1 is dwelling to 10 replaceable grub screw-like pins per aspect. Whereas they aren’t as tall or aggro as different pin designs, they do the job very effectively. The connection feels safe, even when stress via the pedal is diminished momentarily; on the prime of the pedal stroke when climbing, for instance.

Put on & Tear
Sadly, after simply three rides, a small however nonetheless detectable quantity of play developed on the spindle. It’s not a lot that it’s noticeable whereas using, although. I continued to watch the play, however it hasn’t worsened within the 20 rides since.
I just lately disassembled the pedals to check out the upgraded seal system. Whereas a not insignificant quantity of mud had managed to infect the internals, the outboard bushing remained uncontaminated, with an inexpensive quantity of grease on the spindle’s finish. Sadly, we are able to’t say the identical for the inboard aspect.


Behind the steel plate, which sits behind the primary seal, are two plastic covers that snap onto the inboard finish of the spindle. The place the 2 covers meet, there’s a slight hole that has clearly permitted some quantity of water and filth ingress. Certainly, beneath the plastic covers, the spindle is displaying indicators of rust.
I repacked the internals with grease, which eradicated the small quantity of play. However, one moist trip and a hose wash later, the play was again. I feel these pedals would require common re-greasing all through the winter months to forestall untimely put on on the bushings and corrosion of the spindle.
We haven’t been in a position to absolutely service the Stamp 1 pedals but however, we’re instructed that no particular instruments are required.


Power
I’ve not been probably the most cautious proprietor of the Stamp 1 pedals. I’ve carelessly dragged them towards ruts and smashed them off roots and rocks on many events. That’s all because of ill-timed pedal strokes, slightly than the pedal being overly-chunky. It’s truly one of many thinner pedals i’ve had on take a look at through the years.
Regardless of that abuse, it’s pleasing to report the pedals are very a lot in a single piece. There’s solely minor aesthetic harm to report. All twenty pins have remained firmly in place and considerably unscathed.
