SDG Comp Pedals: Composite Flat Pedal Specs and Fit

What the SDG Comp is

The SDG Comp is a composite flat pedal from SDG Components, the brand better known for mountain-bike saddles and dropper posts. It pairs a composite platform with a machined chromoly spindle and 9 replaceable pins per side.

It sits in the value end of the flat-pedal market: you get proper pins and serviceable internals, but in a composite body rather than machined aluminum.

SDG Comp pedal design: body, spindle and pins

Body. Composite (reinforced plastic) is the material of choice for budget trail flats. It flexes slightly and tends to skate off rocks, where an alloy edge can catch and stop the pedal dead.

Spindle. The machined chromoly spindle carries the load, so the composite body does not have to. This is the same basic recipe used on most good composite flats.

Pins. The 18 pins per pedal load from the bottom. If a pin snaps or bends over after a rock strike, you can usually back it out from underneath instead of fighting a stripped head on top.

Internals. A bearing and bushing system that can be rebuilt. That matters on a composite pedal: the body usually outlives a few sets of internals if you look after it.

Composite vs aluminum: is the SDG Comp right for you?

Choose a composite pedal like the SDG Comp if you ride rocky trails, want a pedal that glances off obstacles and do not want to pay for a premium alloy flat. A scuffed composite body is also cheaper to replace.

Choose an alloy flat if you want the thinnest possible profile or the longest body life under heavy rock strikes. Our flat pedal guide compares both, and platform pedals covers simpler commuter-style options.

Setup and fit notes

• Thread: 9/16”; it will not fit one-piece cranks with 1/2” threads.
• Left pedal: reverse-threaded. See which pedal is reverse threaded before you pick up the wrench.
• Grease: a thin coat of grease on the threads stops creaks and makes removal easier later.
• Pins: run them all at first. If you cannot reposition your feet, remove a couple of the inner pins before shortening the outer ones.
• Shoes: a flat-pedal shoe with soft rubber gets the most from the pins.

How the SDG Comp compares

Against the DMR V8, the Comp trades a metal body for composite. The V8 suits riders who prefer alloy durability; the Comp suits riders who want a pedal that slides off rocks.

Against premium alloy flats such as the Wolf Tooth Waveform or Hope F22, the Comp is a lower-cost option with simpler internals. Those pedals add machined alloy bodies and three bearings plus a bushing.

See the SDG brand page for the rest of SDG’s range.

Care and wear

Composite bodies wear at the leading edges and around the pin bosses. Check pins after any big strike and replace bent or snapped ones before the threads in the body get damaged; our pedal pins guide covers removal.

If the pedal develops play or feels gritty, rebuild the bearing and bushing rather than replacing the pair.
