Elite Turbo Muin Fluid Trainer. Not only is the Elite Turbo Muin the quietest indoor trainer on the market, it's the first direct drive trainer with fluid technology! It utilizes 100% of your energy by replacing the rear wheel of your bike, so you get higher output, increased stability and no tire slippage. Integrated fluid resistance runs super silent, super smooth and feels super realistic, plus the resistance is progressive, so the harder you pedal, the greater the resistance. Large 13lb flywheel has a maximum power curve of 2500 watts when pedaling at a 60kph pace. It's compatible with Shimano 9/10/11-speed cassettes, plus 130mm/135mm road and mountain bike hubs with standard diameter quick-release on the rear wheel. Cycling stats from the Turbo Murin Fluid Trainer can be broadcast via ANT+ to Elite's My E-Training App on your Smartphone or Apple device, so you can manage power, pedal cadence, heart rate, speed, time and distance, plus map races, create training programs, and more.
