Today, we embark on a greasy two-wheeled journey through the exciting and sometimes perplexing world of drivetrains. Understanding drivetrains can be confusing, but we’re here to help you unravel the mystery.


Chainrings come in many different sizes and are the backbone of your bike’s shifting prowess. A simple way to make shifting easier, or more difficult, is to replace a chainring. Just make sure your new chainring has the same number of bolts. Also, bigger chainrings = easier to pedal.

Rear Cassette
The cassette or freewheel, as some call it, is where the magic happens. It’s a wild arrangement of teeth, waiting to engage with your chain and propel you forward. With options ranging from a handful of smaller cogs, to cogs the size of your face.


Derailleur Delight
These clever contraptions shift your chain from one cog to another with graceful precision. When you’re out on your bike, shifting gears should feel like conducting a symphony. Smooth, harmonious, and even magical at times. If that doesn’t sound like your derailleur, it may be time for an adjustment or chain oil.

We hope you’ve learned a thing or two about these quirky yet essential components. Embrace the joy and occasional challenges that come with the ever-spinning world of gears. Happy cycling!
