Why Removing Your Crank is Important for Mountain Bike Maintenance
Mountain biking is an adventurous sport that requires proper maintenance of the bike.

Moreover, removing the crank gives you an opportunity to inspect and replace your chainring, pedals or, bearings that may need attention. In summary, performing routine maintenance on your mountain bike ensures its longevity, enhances your riding experience, and above all, improves safety.
