SportCrafters OverDrive Pro Rollers $399.00
The all-in-one trainer.
Rollers have been regarded as the go-to winter training option by professional riders for years. Besides providing a consistent workout, rollers also promote balance and core-strengthening. The biggest drawback has always been that rollers only provide so much resistance — until now. The SportCrafters OverDrive Pro Rollers use progressive resistance to combine the benefits of roller training with the resistance of a fluid trainer.
The OverDrive Pro Rollers look identical to the Cadence Rollers. They were machined from aluminum and feature 3.25in drums with .125in-thick walls. They are 15.5in wide and were lathed on the axle for precision runout and balance, and they're dynamically spin-balanced — they will not distort in heat or sunlight. As with all SportCrafters rollers, the bearings are greased and sealed and need no maintenance. The steel framework is zinc-plated and powder coated for durability. So, what makes the OverDrive Rollers different? Well, they incorporate the use of progressive resistance. This means that as the rollers spin faster, resistance increases in a non-linear fashion. This gives you all the benefits of balance and core strength development from traditional rollers with the added resistance found in stationary trainer units.
The Rollers are designed to fit wheel sizes 600 to 700c and 26 to 29in. It will accommodate wheelbases from 37.5 to 44in, as drilled. There is no rider weight limit. The rollers' unfolded dimensions are 60 x 20 x 4.25in, and folded it is 31.5 x 20 x 5.25in. As with all SportCrafters' rollers, they have a lifetime warranty and are made in Granger, Indiana.
The SportCrafters OverDrive Pro Rollers come in one size and one color.
