If when pedaling you feel a grinding sensation, see below what you can do.

Backward compatibility

This guide is compatible with legacy 135mm solid axle hubs (Commercial/CO, Sportive/SP, Cargo/CA, N360, N380, N380SE), and 148mm modular axle hubs (Sportive/SP, and Cargo/CA).

Problem diagnosis

Inspect the bicycle. Follow this guide if you detect:

• A grumbly or grind sensation that can be felt through the pedals.
• A pedaling sensation that resembles sandpaper or a “buzzy” ride feel.

Solution

If the hub is within 2 years of age, return the hub or wheel using the warranty request form. enviolo hubs are closed containers and need to be sent back for closer inspection.

Done

With a hub still in warranty, you should have sent it to our Service Center for closer inspection.

For any questions, please contact support.
