Flat pedals remain the right choice for many riders, and a wide platform with sealed bearings is a good upgrade from stock plastic.

What the listing publishes

A 9/16 inch thread, L and R marks, sealed bearings, a chrome-molybdenum spindle, a 101 mm platform and a 0.66 lb (302 g) weight in the bullets, with 320 g in the table.

What sealed bearings give you

Less water and grit reaches the bearing, so the pedal stays smooth longer. That matters most for riders who ride through winter.

What to check before you buy

Grease the threads before fitting. The left pedal has a reverse thread: tightening it the normal way can ruin the crank.

The questions riders ask

Will they fit my bike?

Most adult bikes use 9/16 in. Some older and kids' one-piece cranks use 1/2 in, and these will not fit.

Which pedal goes on which side?

ROCKBROS marks L and R. The left pedal threads backward, so turn it counterclockwise to tighten.
