This is the newest version of the Gusset Slim Jim CNC flat pedal.
It receives performance-enhancing updates over the old model thanks to a new shape and look.
The body is made from machined 6061 aluminium and runs on an LSL bushing and sealed cartridge bearing with a chromoly steel axle.
Gusset Slim Jim CNC details and specifications
The latest Slim Jim CNC pedal has a 101(W)x95mm(L) body at its widest points. Its trailing and leading edges are chamfered, measuring 18mm deep.
At its narrowest, the central axle housing is 14mm thick, but has 16mm bulges on both the inboard and outboard ends. This gives the platform an overall concave shape, even if it’s only slight.
They have 10 replaceable back-loading pins around the pedal’s perimeter, each protruding by 3.5mm.
Eight spare pins are supplied, along with the Allen key to install them. My pair of test pedals weighed 398g.
Gusset Slim Jim CNC performance
Despite the platform not feeling huge underfoot, it wasn’t so cramped that I ended up pushing my feet hard against the cranks or overlapping the pedal’s edges.
This meant my feet were stable and supported with clawing limited, helping improve control and reduce fatigue.
Despite the inboard and outboard bearing bulges sitting just 2mm lower than the front and rear edges, I couldn’t feel them through my feet.
Instead, my foot’s pressure was driven firmly into the sharp, well-positioned pins.
The pins penetrated my shoes, providing immense grip and stopping all foot twist, even on rough terrain.

Gusset Slim Jim CNC bottom line
The Slim Jim CNC was a bit of a surprise performer, given its compact size and marginally concave shape.
Pin location and size, combined with the platform’s profile, gave impressive performance.
Furthermore, the modest asking price is tricky to ignore, putting it closer to composite pedals than alloy ones.
To improve performance further, I’d love to see the same design with a larger platform at a similar price, but this version is definitely worth your cash.
