Kreitler 4.5 Challenger Rollers


Kreitler 4.5 Challenger Roller with Headwind

Kreitler designs top of the line rollers that will help you develop better balance and technique, increase your cadence, and improve your power.

The 4.5 drums have low resistance and are the recommended choice for riders learning to use rollers. Most riders will be able to push large gears and keep the wheel speed high with relatively low effort. Higher wheel speed enhances balance and provides a greater coasting effect if you stop pedaling momentarily.

This version comes with a standard Kreitler frame that works with all Kreitler drums and accessories. It also covers a wide range of wheelbases. There are also two extension kits available for longer bikes such as recumbents and tandems.

The Challenger 4.5 Rollers use the same 4.5" machined aluminum drum cylinder as the Alloy 4.5 Rollers, but use Poly end caps for a more economical option.

What's included:

  • 4.5" x 15” Alloy Drums with Poly End Caps
  • Standard Kreitler Frame
  • Belt

Great rollers - Oct 30, 2013

5 out of 5 stars

I've owned these for a couple of years and because I have to train often at night they get used several times a week. Mine have well over 10,000 miles on them. Except for replacing the rubber band (keep some for replacement), they are as good today as new. Highly recommended if you have to use rollers. I use the Headwind accessory for a better workout.
