Dirt Jumping is the practice of riding bikes over shaped mounds of dirt or soil and becoming airborne. A full afternoon of laps leaves your bike caked in grime that works into every pivot, seal and chain link. The riding is the fun part — the ten minutes you spend afterwards decide how long your bike lives.
The post-ride ritual
Do not let mud dry on the frame. Dried mud acts like sandpaper every time a linkage articulates, and it hides the cracks you actually want to see. Rinse the bike with a gentle stream, brush the drivetrain with a degreasing soap, and dry it with a clean rag before any inspection.
A five-minute rinse straight after the last lap saves hours of rebuild work later.
The five-step checklist
- Rinse low and gentle — high-pressure jets push water past fork seals and bearing seals.
- Brush the drivetrain — cassette, chainring and jockey wheels first, degreaser second.
- Check the pivot bearings — lift the front end, rock the bars, feel for notchiness.
- Inspect the frame — mud hides cracks around the head tube and rear triangle.
- Lube the chain — wet lube for winter slop, dry lube once the trails dust over.
If you only remember one thing: a clean bike is a quiet bike. Squeaks are your suspension telling you it is already too late.
Dial in pressure & protection
Muddy lines change how much grip you have on offer, and your tire pressure should change with them. Drop a few PSI for penetration, and match your lube to the weather instead of the calendar.
| Condition | Tire pressure | Chain lube |
|---|---|---|
| Deep mud | -3 PSI | Wet lube, wipe excess |
| Damp loam | -1 PSI | Wet lube, light coat |
| Dry and dusty | Standard | Dry lube after every ride |
Watch: the full walkaround
Ride it, wash it, check the pivot bearings, and lube the chain — the ritual that keeps a mountain bike alive through a muddy season. Ten minutes of maintenance buys you a full season of laps.
