Protaper Twister Throttle Tube

Protaper Twister is a good quality throttle tube with a sealed ball bearing which makes the throttle tube easier to rotate, which offers you increased throttle response and prevents dirt from penetrating into the ball bearing, which can cause the tube to get stuck.
Don't let a little bump ruin your race day - this aluminium throttle tube can withstand a lot more than your standard plastic throttle tube.

- Ribbed surface so that the rubber grip will be properly attached.
