Belts Have A Long Service Life
You can expect a regularly cleaned belt drivetrain to last upwards of 30,000km/19,000mi. Additionally, belts will not rust if they get wet regularly (or are subject to salt near the beach).
Belts Require Little to No Maintenance
You don’t need to lubricate or degrease your belt. The most maintenance you’ll have to do is get a toothbrush and give the belt a scrub from time to time.
Belt Drivetrains Are Silent
You know when your chain is freshly cleaned and lubed and running perfectly silent? That’s a belt most the time (occasionally I need to apply silicone lubricant).
Belts Are Marginally Lighter Than Chains
You can expect a weight saving of around 100 grams when compared to chain drive.
