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, beneficial for EU Sizes 35-43.5 (US 3-10, and UK 2-9)
- The Stamp 1 Massive measures 111mm vast, and 114mm lengthy, beneficial for EU Sizes 43.5-49 (US 10-15, and UK 9-12+)
Extra vital modifications come on the within, with a chromoly metal spindle and low friction IGUS bushings, and an upgraded seal system that can 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 spread of opposed situations.
The updates are stated to stop 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 | Assessment
As a wearer of UK Measurement 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 refined 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 ultimate, it could actually truly present a really safe locked-in really feel, however it could actually additionally result in foot fatigue.
Given the great grip i’ve skilled with the Stamp 1 pedals, i’m inclined to say that Crankbrothers have discovered stability with the refined 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 house to 10 replaceable grub screw-like pins per facet. Whereas they aren’t as tall or aggro as different pin designs, they do the job very nicely. The connection feels safe, even when stress via the pedal is lowered 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 driving, although. I continued to observe the play, nevertheless it hasn’t worsened within the 20 rides since.
I not too long ago disassembled the pedals to try 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 facet.
Behind the metallic 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 experience and a hose wash later, the play was again. I believe these pedals would require common re-greasing all through the winter months to stop untimely put on on the bushings and corrosion of the spindle.
We haven’t been in a position to totally service the Stamp 1 pedals but however, we’re advised 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 in opposition to ruts and smashed them off roots and rocks on many events. That’s all because of ill-timed pedal strokes, reasonably than the pedal being overly-chunky. It’s truly one of many thinner pedals i’ve had on take a look at over time.
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.
