Bonnell MX Custom Sprockets (775 MX Performance Upgrade)

Precision Gear Ratio Upgrade for Speed, Torque & Terrain Control

The Bonnell MX Custom Sprockets are performance drivetrain components designed specifically for the Bonnell 775 MX platform, allowing riders to fine-tune their bike’s speed, torque, and riding behavior based on terrain and riding style.

These sprockets are a key upgrade because the 775 MX uses a fixed single-speed system, meaning your sprocket choice directly controls how the bike performs.

Available Sprocket Sizes & Performance Impact

The Bonnell MX sprockets are available in multiple tooth sizes, each designed for a specific riding style:

22T (High-Speed Setup)

• Top speed: ~40 mph (65 km/h)
• Best for open trails and speed-focused riding
• Lower torque for steep climbs

24T (Stock – Balanced Setup)

• Top speed: ~37 mph (60 km/h)
• Balanced mix of speed and torque
• Ideal for general trail riding
• Comes pre-installed on the bike

26T (Torque Upgrade)

• Top speed: ~34 mph (55 km/h)
• Increased low-end torque
• Better for technical trails and climbs

28T (Maximum Torque Setup)

• Top speed: ~31 mph (50 km/h)
• Maximum climbing power
• Ideal for steep hills and extreme terrain

How Sprocket Size Affects Your Ride

Choosing the right sprocket is critical due to the fixed-gear design:

• Smaller sprocket (22T) → More speed, less torque
• Larger sprocket (26T–28T) → More torque, less top speed
• Mid-range (24T) → Balanced performance

This means your sprocket directly determines whether your bike feels fast and aggressive or powerful and controlled.
