Drivetrain Service FAQ

How often should I service my drivetrain?

For regular riders, a full drivetrain service every 2,000-3,000 miles is recommended. E-bike riders in Lake Mary and Sanford should service more frequently due to higher torque loads. A basic chain replacement may be needed every 1,500-2,000 miles.

What's the difference between threaded and press-fit bottom brackets?

Threaded bottom brackets screw into the frame and are traditional, reliable, and serviceable. Press-fit BBs are pressed into the frame with specialized tools and are common on modern carbon frames. Our Sages carry tools for both types and can advise on the best option for your bike.

Can you service e-bike drivetrains?

Absolutely. E-bike drivetrains experience significantly more wear than traditional bikes. We service all e-bike brands and motor types, including mid-drive systems where the drivetrain takes the most abuse. Combine with our power diagnostics for a complete e-bike health check.
