All of our products are designed as set-and-forget products to last as long as possible. However, like all mechanical products, following service interval guidelines are strongly recommended, and will become mandatory if left long enough.

The ZonePro should be serviced every 150 hours of riding. Follow our service guidelines on our Product Support page here.
Keep an eye on chain wear. A major advantage of a single-speed setup is reduced wear on chains due to a lack of lateral loading. However given enough use the chain will wear, causing wear to your chainring, rear cog, and jockey wheels. Please consult your local bike shop, or measure your chain wear frequently to keep on top of this.
