Wise CrMo 16T Freewheel

Product Overview

The Wise CrMo 16T Freewheel is a durable single-speed rear cog engineered for BMX racing and street riding. Built from chromoly steel with three-pawl engagement, it delivers reliable power transfer and responsive acceleration. Standard 1/2 x 1/8" chain compatibility works with all BMX drivetrain systems.

Key Features

• Chromoly steel construction – Premium material provides superior strength and durability compared to standard steel. CrMo resists bending, cracking, and wear from repeated impacts and aggressive riding. Maintains consistent engagement across extended use without deformation.

• 16-tooth single-speed cog – Moderate tooth count balances acceleration with top-end speed. Appropriate gearing for racing, street tricks, and general BMX riding without excessive pedaling resistance or sluggish engagement.

• Three-pawl engagement system – Three-point ratchet mechanism provides responsive power transfer with minimal rotational lag (approximately 15-degree engagement angle). Improves acceleration feel during racing and trick initiation.

• 1/2 x 1/8" chain compatibility – Standard BMX chain pitch and width. Compatible with all current 1/8" drivetrain systems including KMC, Taya, and other BMX chains.

• Black finish – Durable powder-coat or anodized finish resists corrosion and maintains appearance through extended use.

• Standard hub threading – 1.375 x 24 hub thread size fits all conventional BMX rear hubs with freewheel compatibility. Compatible with most standard rear hub designs.

• 4 and 8-notch removal tool compatible – Works with standard freewheel removal tools available at most bike shops. Simplifies maintenance and cog replacement without specialized equipment.

• Freewheel design – Allows coasting without pedaling, enabling trick setup and recovery without continuous leg movement. Standard engagement mechanism provides reliable power transfer during pedaling.
