Convert any sealed mid bottom bracket to the DRS system.
What is DRS? This is a system designed and patented by Vocal that allows you to add drag to your cranks to stop them turning when you take your feet off the pedals. The system works with a simple plastic drag plate that runs on the outer face of the bearing. The system can be adjusted to suite the individual riders style, so no more searching for your pedals when you do a tail whip they will be exactly where you left them.

Comes with

• DRS System 3 screw adjustment, drag washer for non driver side
• 2x CNC alloy 3mm spacer shims
• Allen key short reach
