The Kreitler Challenger Rollers is an ideal method of resistance training in compact, portable package. For almost 40 years, Kreitler has been producing some of the smoothest and quietest rollers on the market. Some would say Kreitler Rollers are the “Rolls Royce” of rollers; beautifully machined while offering the best combination of resistance, cost, and portability. Kreitler rollers will simultaneously allow you to increase your cadence, increase power, and improve your form all while helping you develop better balance and technique. Regardless of your current skill level, there is a Kreitler roller system that will help you become a better cyclist.
Kreitler rollers are offered in several different drum diameters; as the drum diameter decreases, the resistance of the roller system will increase due to the bearing and tire friction. At any given speed, a smaller drum will need to rotate at a faster RPM than larger drums, causing more friction in the bearings which ultimate producing higher resistance.
The Challenger series of Kreitler Rollers use the same standard Kreitler frame as the Alloy series, the only difference being the use of polycarbonate end caps in place of alloy ones, which provides for a more economical choice with the same quality and performance expected from a Kreitler Roller. The Kreitler Challenger 3.0 Rollers provide 40% more resistance compared to the Challenger 4.5 while the Challenger 2.25 Rollers provide a whopping 90% more resistance compared to the 4.5 models.
*Please Note: Use of the Kreitler Headwind Fan or Flywheel accessories on 3.0 and 2.25 drum sizes will cause premature wear on the poly end caps, which is NOT covered under the lifetime warranty. If you are planning on using either of these accessories with your Kreitler roller system, alloy end caps are recommended.
