Elite Turbo Roteo Trainer. For the ultimate in indoor workouts look no further than the Elite Turbo Roteo Trainer. Unlike the standard trainer design in which your bike's rear wheel spins on a drum attached to a resistance unit, with this system the rear wheel is removed and replaced by the Turbo Roteo trainer. The advantage of this direct drive system is that under heavy load such as during standing starts, accelerations, and intense sprint sessions there's no slippage of the rear wheel on a roller drum as your bike's drivetrain is directly attached to the resistance unit. You'll get to use 100% of your energy together with progressive fluid resistance to experience the higher output, increased stability, and super quiet performance of a direct drive trainer. Its integrated fluid resistance runs super smooth and feels super realistic, plus the resistance is progressive, so the harder you pedal, the greater the resistance. Not only that, its 3kg steel flywheel replicates the feel of the road and runs seamlessly, even at low RPMs. The trainer is compatible with Shimano 91011 speed cassettes, frames that utilize 130mm or 135mm width hub spacing and standard quick release levers, as well as frames with 142x12 rear thru axle systems.
