CASSETE LEONARDI FACTORY GENERAL LEE 12V 9/48

The best choice for 1×12 transmissions. Up to 33% more development than current 12V transmissions. It goes up slightly with 48 and down without losing development with 9. Minimize jumps and weight with the 946 or expand your range without limit with the 948. Machined steel from a solid block, hardened and superficially treated to improve durability, sonority and corrosion resistance. New and optimised shifting, gearing and quieter shifting phases even under stress thanks to the SharkFin tooth profile.
