The internals of the Speed Spool ITB 200 feature 9+1 ball bearings, a P2 Super Pinion double-bearing-supported pinion gear, machined aluminum drive gear, and ParaMag ITB braking. This adaptive magnetic brake system gives anglers incredible castability across a variety of baits and conditions by automatically adjusting during the cast, always providing the right amount of force while virtually eliminating the need to thumb the spool.
