Product Details

Built for BMX Performance.Engineered for Tricks & Impact.

Designed specifically for BMX performance riding, GT-017F/019R features a reinforced 6-pawl / 3-tooth engagement system with 120 clicks, delivering rapid engagement response and efficient power transfer. The multi-point engagement structure helps distribute drivetrain loads more evenly, providing consistent engagement performance and reliable durability during jumps, hard landings, and demanding freestyle riding.

36% Contact Width**

6-Pawl Reinforced Engagement System with Wide Pawls

The upgraded pawl width increases by approximately 36%, creating a larger engagement surface for improved torque transfer and reduced stress concentration.

35% Load Bearing Surface

Wide Drive Ring for Greater Load Distribution

The drive ring width increases by approximately 21%, expanding the load-bearing area by approximately 35% and improving overall hub fatigue strength by approximately 30%.
