Cedar Pointâs Top Thrill Dragster relies on the power density of hydraulics. August 29, 2014 By Mary Gannon Leave a Comment.

Baitcasting/Trolling/Spincast reels use a star-shaped wheel located on the reel handle called a star drag, adjustments are made by turning the wheel to the proper tension. Spinning reels have two types of drags â front drag and a rear drag. Front drags are generally smoother than a rear drag. The front drag features larger, multiple disc drag washers on the spool that offer a higher level of performance and durability. The rear drag uses applied pressure on the drive shaft.
