Rayomandwrote a review of SportCrafters OverDrive Pro Rollers on January 26, 2015
Familiarity: I've put it through the wringer
First on Rollers itself- If one hasn't tried it before and read / watched scary reviews / videos then don't get bogged down by them, its quiet easy to work out on the rollers. It took me 10 mins to get used to them initially and after few workouts became second nature. Now i have hard training sessions on them lasting 2 hrs.
Now specific to SportsCrafters- i got the Resistant unit and am quiet satisfied with the power curves. The plastic cup of the unit did crack up and warranty replacement was bang on to their claim. Upgraded the drums to High Inertia Drums which provide much more rolling coasting which is necessary to sustain longer training hours. I had been using Fixed Trainer with Progressive unit but find that Rollers are much better workout for same effort / time as they improve bike balancing skills and keeps you alert and out of boredom during session. Sprinting out of saddle workouts ain't possible as bike tends to get off if force is applied.
