A suspension post lifts rough-road comfort more than any saddle. The price of that is a little movement while you pedal.

What the listing publishes

A built-in spring coil and damper rubber, sizes that DJC warns are not interchangeable, a clamp angle from -5 to +18 degrees, a 14 mm offset, full 6061 aluminum, a stated compliance with ISO 4210, a 2-year coverage, and a rider range of 110 to 220 lb.

Who should fit one

Anyone on a rigid bike who rides broken pavement and sits upright. Road riders at high cadence will feel the bob. Set the preload so that the post sags slightly with you seated.

What to check before you buy

Measure twice. A post that is 0.4 mm too small will slip, and a post that is too large will not go in. Then check your minimum insertion mark, because a suspension post adds height.

The questions riders ask

How do I find my size?

Read the number stamped on your current post, or measure it. DJC warns that sizes are not interchangeable.

Can it be adjusted for my weight?

DJC says the bottom screw adjusts the preload, for riders from 110 to 220 lb.
