Why Choose This Gear Set
If you want a simple way to boost top speed on a TRX-4M, this gear set gives you the internal parts and pinion to do it without machining or complex changes. It's a good match for drivers focused on pavement, hard-packed trails, or flat course runs; avoid using it where the drivetrain faces sustained high resistance.
