The Magnum Force™ weight is the latest clutching technology, improving the clamping efficiency of the weight (especially at low to mid speed ranges). It utilizes external adjustability by means of a gun drilled and threaded center core, where mass can be added or subtracted without removing the weight from the clutch.
 
This new weight works through its unique mass distribution profile, combining maximum shift force on the low end with excellent top end performance. Its striking profile utilizes our most efficient heavy heel design yet, with instant response and increased acceleration that are sure to satisfy any performance-hungry rider. This weight does it all, aggressive shift profile with ease of tuning.
