The Vortex 154ZK-53 is a 520-pitch, 53-tooth CAT5 aluminum rear sprocket finished in black anodize. Designed for Vortex Racing's performance-minded CAT5 lineup, this sprocket is 100% CNC-machined in the USA from a specially formulated aluminum alloy per Vortex specifications, delivering a significant weight reduction over OEM steel sprockets.

Key Features:

• 520 Pitch — compatible with 520-size chain setups including OEM replacements and suitable 520 conversions
• 53 Teeth — higher tooth count for increased low-end torque and acceleration
• CAT5 Aluminum Construction — lightweight aerospace-grade alloy machined to Vortex specifications
