Description

Standard round rollers roll. Dr. Pulley sliders slide. This patented design allows your variator to open further and close faster, broadening your gear ratio for faster acceleration and higher top speed — without the premature wear of traditional round weights. Available in 13g, 14g, and 15g to suit your riding style. Sold as a set of 8.

Performance Benefits:


  • Faster acceleration: Sliders reach the bottom of the ramp faster for immediate throttle response off the line

  • Increased top speed: Unique shape allows the pulley to close further, pushing the belt higher for maximum velocity

  • Extended service life: Self-lubricating PA46 tribological composite lasts 18% longer than standard weights with 22% less material loss

  • Anti-wear design: Eliminates flat-spotting even during extended high-RPM operation (U.S. Patent 7,276,004)

Features

  • Patented sliding mechanism for broader gear ratio
  • Faster acceleration and higher top speed vs. round rollers
  • Self-lubricating PA46 tribological composite

Tuning tip: For more acceleration, choose a weight 10–15% lighter than stock. For more top speed, match your factory roller weight. Orientation is critical — ensure the Dr. Pulley logo faces the correct direction during installation.
