The G2 Progressive Rate Trials Throttle tube for Vertigo provides increased control where needed off idle, then ramps up to keep overall rotation at a comfortable range. The initial rate is same as the Domino BLACK Trials Throttle Tube, which provides great control. However, the BLACK throttle tube requires far too much turn to reach wide open. By increasing the rate at mid-throttle, rotation is nearly same as the WHITE throttle tube. It’s the perfect compromise between the two!
The throttle tube consists of the ultra-smooth G2 tube with Delrin inserts. The cam (or “pulley”) end is the same rate as the Domino WHITE (Fast) plastic throttle tube.
