John Gwrote a review of Elite Arion Roller on January 6, 2016
Familiarity: I've used it several times
Bought this to keep pedaling during the El Nino in S. California when the trails are too muddy. Have about 75 miles over 10 or so uses on this roller. I set up my 29er MTB with slicks, works great. Like being able to take the bike as it sits, throw it on the roller and get to pedaling. The parabolic rollers help make the learning curve quick and to keep you centered when pedaling. Workout intensity is light to moderate but requires a focus on balance and smooth cadence. It has helped my form and cadence techniques for the real rides.
