Crankbrothers Stamp 7 (large) mountain bike flat pedals

Our review

Exceptional grip and stability thanks to a large platform and well-placed long, sharp pins
Pros: Great grip; plenty of platform real estate reduces clawing and improves stability; adjustable and removable pins; neat design touches such as grease port
Cons: Some customisation required

The feature-laden Crankbrothers Stamp 7 pedals are available in two versions: small for foot sizes 37-43, and large for feet 43-49.


Both the small and large pedals share their design, shape and number of pins.

I’ve tested the large, because they’re best suited to my UK size 8 feet.

Crankbrothers Stamp 7 Large details and specifications

The large Stamp 7 pedals have a 109(L)x111mm(W) platform at its widest point, measuring slightly smaller than Crankbrothers’ claims.

They have chamfered front and back edges that are 14mm deep, while the narrowest point on the central axle housing is also 14mm deep.

The widest point on the axle is at the pedal’s inner edge, where the pedal’s body tapers up to a bearing bulge measuring 20mm deep.

There are 10 grub-screw style adjustable studs, with eight placed around the pedal’s perimeter and two in the central section.

The six front- and rear-edge pins protrude by 5mm, while the remaining four are 2mm long. Included with the pedals are 24 long and 16 short extra pins.

The pedal’s body is made from forged 6061 T6 aluminium, spinning on a 435 chromoly steel axle using IGUS LL-glide bearings. The body has a dedicated grease port, too.

The Stamp 7 is offered with a five-year warranty. My test pedals weighed 379g.

Crankbrothers Stamp 7 Large performance

With a massive concave platform and well-placed pins, the Stamp 7 offers an exceptional amount of grip.

I found adjusting the stock pin arrangement, by replacing the shorter outer-edge pins for longer ones and removing the central shorter pins, significantly elevated traction because it mitigated against the wedge-shaped axle housing by lifting the outside edges of my feet.

Once placed, my feet refused to budge, and thanks to the large platform off-centre foot placement wasn’t punished by a reduction in traction or stability.

The size large Stamps are better suited to people with larger feet.

The large surface area meant my feet didn’t claw, which helped reduce fatigue and improved stability and traction.

The pedals brushed off ground strikes well, and their slim overall profile meant contacting the ground only happened infrequently.

Their impressive size-to-weight ratio means they’re comparable to pedals with a smaller platform, but deliver improved grip without massive weight penalties.

How we tested

We’ve tested 13 flat pedals for mountain bikes in some of the harshest conditions on a host of terrain types – from bumpy on-the-gas sections through to flat-out rough and worn downhill tracks – to see how much grip they offer and help you find the perfect companion.

Crankbrothers Stamp 7 Large bottom line

Impressive grip and stability mark the Stamp 7s as true top performers, pitting them directly against the Deity TMAC in terms of performance and price.


There’s little to differentiate the two, and both are exceptional pedals that offer extraordinary grip in an impressive package.
