How long do suspension pivot bearings last?

Typically one season of regular riding: check annually, replace every 1–2 years. Pivot bearings rotate a few degrees under high load, which kills them faster than spinning bearings. Wet climates and pressure washing can halve that.

How do I know if my bearings are worn?

Grab-and-rock tests: side load the rear wheel for hub and pivot play, turn bars slowly for headset notchiness, rock the cranks for BB play. Any notchy rotation, play or rumble means the bearing is done; they don't recover.

Does pressure washing damage bike bearings?

Yes. A pressure washer drives water and grit past bearing seals, and the damage shows up weeks later as creaks and notchiness. Use low-pressure water and a brush around all bearing areas.

Bearings: the quiet parts that ruin loud rides

Every creak, knock and wandering rattle you've ever chased was probably a bearing. They die slowly, invisibly, and always blame some other component first. Here's the full map (pivots, hubs, headset, bottom bracket) and the intervals that keep them silent.

Intervals by bearing

Bearing	Check	Typical life	Failure signature
Suspension pivots	1 yr / 100–150 h	1–2 yr	Creaks under pedalling, rear-end play, "loose" feeling in corners.
Wheel hubs	1 yr	2–3 yr	Rumble when coasting, side play at the rim, dragging freehub.
Headset	1 yr	2–3 yr	Notchy steering straight ahead ("indexed" bars), knocking on the front brake.
Bottom bracket	1 yr / 100–200 h	1–2 yr	Creaks under power, gritty crank spin with the chain off.
Freehub / ratchet	1 yr, grease service	varies	Skipping engagement, screaming coast, pawls sticking in cold.

Wet climate or bike park? Halve everything above. A UK winter or a lift-served summer is a full career for pivot bearings. Dry climates stretch the same bearings to double.

Why pivots die first

A wheel bearing spins; a pivot bearing rocks through a few degrees millions of times under full rider load. The balls never circulate the grease, the same two contact patches take every hit, and water sits in the tunnel where the frame traps it. That's why pivots are annual-check items even on bikes that "barely got ridden".

The 60-second bearing check

Rear end: grab the seat stay and rock laterally; any click or play is a pivot or hub.
Headset: front brake on, rock the bike fore-aft; then lift the front and turn the bars slowly, feeling for notches.
BB: drop the chain, spin the cranks: they should spin smooth and silent; rock each crank arm for play.
Hubs: wheel off the ground, side-load the rim; spin and listen for rumble.

Make them last

No pressure washing near seals: hose and brush only around pivots, hubs, headset and BB. Jet wash damage shows up three weeks later as creaks.
Re-grease, don't just replace: popping seals and refreshing grease annually doubles bearing life for the cost of ten minutes per bearing.
Torque check pivot hardware twice a season: a loose pivot bolt destroys the bearing seat, and that's a frame repair, not a bearing swap.
After a wet season: assume the lower pivots are on borrowed time; check before the next season starts, not after the creaking does.

FAQ

Creak under pedalling: pivot, BB or seatpost?

Drop the chain and spin: silence points to drivetrain load, so BB or pivots. Creak persists while coasting seated? Seatpost or saddle rails. Creak only out of the saddle? Usually pivots or BB. Grease the seatpost first; it's the five-minute suspect.

Can I replace just one pivot bearing?

You can, but don't. Bearings age as a set; if one is notchy the rest are close behind, and the labour of dropping the linkage dwarfs the bearing cost. Do the full set.

Are ceramic or "premium" bearings worth it?

For pivots: no. The failure mode is contamination, not friction. Standard-grade stainless bearings with good seals and fresh grease outlive expensive ones that get pressure-washed.
