We can custom configure cassettes in customer-specified ratios, using 11t through 29t cogs. Miche cassettes are completely modular, so not only can they be custom configured, all cogs can be replaced individually when or if needed or desired. PRICE SHOWN IS HIGHEST ESTIMATED PRICE. Prices vary slightly depending on configuration (for example, 11t pole position and 29t final position cogs cost slightly more than 12t pole and smaller final position cogs). Please call for price and availability. Opaque chrome steel finish.
