Strummer CW-7 Square Taper Chainwheel BCD-104 with Steel Chainring

Strummer CW-7 Chainwheel / Crankset

The Strummer CW-7 Chainwheel / Crankset is designed to provide an optimal combination of stiffness, strength, and ease of maintenance. Suitable for daily use or upgrading bikes with widely used standards.

The crank arm is made of lightweight and rigid aluminium alloy material, allowing pedaling power to be transferred efficiently without excessive flex. The chainring is made of steel to ensure high durability against loads and friction, making it more durable for long-term use.

For maintenance and upgrade flexibility, the CW-7 uses the widely common 104 mm BCD standard in the market. This makes it easy for you to change chainring sizes as needed without difficulty in finding compatibility.

This crankset / chainwheel is compatible with square taper type bottom bracket systems known for their strength, stability, and ease of maintenance.
