For nearly 20 years, SportCrafters has been making private label rollers for CycleOps. Several years ago it developed and patented its ARC Power Modulation Technology, which paved the way for its own line of Cadence and Overdrive rollers. The SportCrafters' Cadence Rollers are precision machined in the USA to challenge both your body and mind.
Designed and manufactured in Granger, Indiana, the aluminum roller drums are 3.25in wide with .125in wall thickness. They are lathed for precision runout and balance and are dynamically spin balanced, meaning they will not distort in heat or sunlight. The end caps are molded polycarbonate, and the bearings are greased and sealed and do not require maintenance -- so you'll have one less thing to think about in the cold of winter. These drums are set into a durable steel frame that has been plated and powder coated to resist corrosion and rust.
Now, if you're wondering why you should ride rollers instead of a trainer -- hours spent on rollers will build core strength and balance. They are also an excellent way to increase leg speed for that sprint. If you want to be able to have the benefits of rollers but also wish to be able to "zone out" at times and just ride and watch a film, add SportCrafters' Fork Stand to your Cadence Rollers to stabilize your bike -- turning the rollers into an all-around trainer. Additionally, the High Inertia Drum may also be added for an extra kick in your workout.
The SportCrafters' Cadence Rollers are available in one size and accommodate wheel sizes 600 to 700c and 26 to 29in. As drilled they will fit wheelbases from 37.5 to 44in. The unfolded dimensions are 60 x 20 x 4.25in and folded dimensions are 31.5 x 20 x 5.25in.
