Wondering when to replace your bike’s components? Follow this guide to find the ideal replacement time to keep your ride smooth.

There are two important milestones in the life of a bike part. The first marks when it should be replaced if you want your bike to work perfectly. The second milestone is when a part needs to be replaced to avoid unnecessary wear on the rest of the bike. Whether you’re a type-A bike maintainer or simply want to get the most miles out of your gear, these are the signals that it’s time for a replacement.


Type-A: Replace it annually or with every second new chain.

Procrastinator: When small indentations start to appear on the backside of the teeth, it’s time for a new one. An excessively worn cassette will shorten the lifespan of the chain, so don’t take it too far.
