Vortex 427ZR-35 CAT5 Rear Sprocket Red 530 Pitch 35-Tooth

The Vortex 427ZR-35 is a CAT5 aluminum rear sprocket featuring a 530 pitch, 35-tooth configuration, finished in a red anodize with contrasting silver machine-cut highlights. Designed as a high-performance upgrade over heavy OEM steel sprockets, this sprocket reduces rotating mass for improved throttle response and acceleration.

Key Features:

• Lightweight CAT5 aluminum construction — machined from aerospace-grade 7075-T6 aluminum for an optimal strength-to-weight ratio
• 100% CNC manufactured in the USA — machined to the tightest tolerances for perfect concentricity every time
• Specially formulated alloy per Vortex specifications for maximum durability
• Vortex patented saber-tooth groove design — unique tooth profile reduces drag, minimizes friction, and increases sprocket longevity
• 530 pitch — compatible with standard 530 drive chains
• 35-tooth rear sprocket — allows for gearing customization
• Red anodized finish with contrasting silver CNC-machined accents for a premium appearance
• Drilled lightening holes on most applications further reduce unsprung rotating weight

The Vortex CAT5 sprocket line is trusted by professional racers and serious street riders alike. Reducing rotating mass at the wheel translates directly to faster acceleration, and the precision-ground tooth profile extends the service life of both the sprocket and the drive chain.
