Strummer CW-7 Chainwheel / Crankset is designed to provide an 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, rigid aluminum alloy, allowing pedaling power to be transferred efficiently without excessive flex. The chainring is made of steel to ensure high resistance to load 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 replace the chainring with a different size without difficulty finding compatible components.
This crankset / chainwheel is compatible with square taper bottom bracket systems, which are known for being strong, stable, and easy to maintain.
Product Specifications

Crank Arm Material: Aluminum Alloy
Chainring Material: Steel
BCD Standard: 104 mm
Bottom Bracket Compatibility: Square Taper
Geometry & System Adjustment
Chainline: Determined by the length of the square taper bottom bracket spindle used. The spindle length selected will affect the position of the chainring relative to the frame and rear sprocket.
Q-Factor: Determined by the length of the installed bottom bracket spindle. A longer spindle will result in a wider distance between the crank arms (Q-Factor).
