If you're a cyclist, sooner or later you'll need to clean and maintain your bike drivetrain. This is the system of cogs and chain that transfers power from the pedals to the wheels. A clean drivetrain makes for a happy bike, so it's important to keep it running smoothly. Here's how to test a bike drivetrain:
1. Check the chain for wear and tear. Look for any missing or damaged links, as well as any stretched or broken chains.
2. Inspect the cassette (the cluster of gears at the rear of the bike) for damage or excessive wear. Check each cog individually for signs of wear or damage.
3. Examine the teeth on all of the cogs and chainrings (the large gears at the front of the bike). Look for any chips, cracks or other damage that could cause problems down the road.
4. Make sure all of the bolts holding everything together are tight and secure. Loose bolts can cause big problems when riding, so it's important to catch them early!
5.Give everything a good lube job before putting your bike back together again - this will help keep things running smoothly until your next maintenance session
