The Strummer CW-7 Chainwheel / Crankset is designed to deliver the optimal combination of stiffness, strength, and ease of maintenance. Suitable for daily use as well as upgrading bicycles with widely used standards.
The crank arms use lightweight, stiff aluminum alloy, allowing pedaling power to be transferred efficiently without excessive flex. The chainring is made of steel to ensure high resistance to loads and friction, making it more durable for long-term use.
For maintenance and upgrade flexibility, the CW-7 uses the widely available 104 mm BCD standard. This makes it easy to change the chainring size as needed without difficulty finding compatibility.
This crankset / chainwheel is compatible with square-taper bottom bracket systems, which are known for being strong, stable, and easy to maintain.

Geometry & System Adjustment
Chainline: Determined by the length of the square-taper bottom bracket spindle used. The selected spindle length affects the position of the chainring relative to the frame and rear sprocket.
Q-Factor: Follows the length of the installed bottom bracket spindle. A longer spindle results in a wider distance between the crank arms (Q-Factor).
