Mounts

Are GoPro mounts universal?

Mostly. The two-prong and three-prong finger interface with a thumbscrew is the de facto standard, and bodies from other makers either copy it or ship an adapter frame that does. The other common fitting is the 1/4in tripod thread found on many camera bases and on out-front computer brackets, and cheap adapters bridge the two. Check which fitting your body uses first — the action cameras listings are worth a look if you are matching a mount to a specific camera.

Handlebar or helmet mount?

A bar mount is steadier and shows the terrain honestly, but it takes every hit through the clamp and fights for space with cables, lights and a computer mount. A helmet mount points where you look, which is better on trails and for reading number plates, at the cost of a higher viewpoint that sways with your head and a camera you forget is up there under low branches. A chest harness sits between the two and picks up your breathing.

What should I check on a used camera mount?

Thumbscrew threads strip and plastic fingers snap, so flex each finger and run the screw fully in and out. On clamps, confirm the rubber shim is present and has not gone hard — most bar mounts ship with 31.8mm and 35mm shims, and a missing one makes the mount useless on your bars. Adhesive helmet and frame bases are single-use: once peeled off, they need new 3M pads, which are cheap and listed under camera accessories. Rounded bolt heads are a sign the mount has been over-tightened.

How much should a used camera mount cost?

Individual plastic parts are only a few pounds new, so buy used for bundles, machined alloy bar clamps, or the specific bracket that hangs a camera under an out-front computer mount. A box of assorted arms, buckles and adhesive bases from someone clearing out a camera setup is usually the best value here. Buy new for anything holding a camera over a front wheel, where a fatigued clamp costs you the camera.
