The science behind chain wear — why clean chains last 3x longer and save €190-600/year in drivetrain costs.

Frequently asked questions

How does dirt accelerate chain wear?

Road grit is harder than steel. Every particle trapped in the chain pin-roller interface acts as a micro-cutter under 80N of pedaling load. A dirty chain stretches 3-5x faster than a clean one, and a stretched chain wears cassettes and chainrings in parallel.

What cleaning frequency actually matters?

Once per week in dry conditions, after every ride in wet or salted conditions. The half-life of grit accumulation on a chain is about 40km in dry weather and 10km in rain — regular short washes beat occasional deep cleans for drivetrain longevity.

Does automated washing damage chains?

No. The cycleWASH Pro uses soft brushes and ≤ 2 bar water pressure — well below the 6 bar threshold where pressure washers start forcing water past seals. Our test fleet logged 12,000 wash cycles on a single chain with no seal degradation.

Should I lube after every wash?

Yes — a wet chain with no lubrication is the fastest way to rust a roller. Modern wax lubes last 300-400km between applications; wet lubes last 100-200km in rain. Apply while the chain is damp, wipe excess after 2 minutes.
