Kreitler 3in Rollers with Flywheel

Description

A
Kreitler Alloy Roller
system is the "Rolls-Royce" of roller systems - masterfully machined, perfectly balanced, and designed for decades of use. The Alloy drums are machined from aircraft-grade 6061 alloy to within two thousandths of concentricity and spin effortless on high-grade ABEC-5 sealed cartridge bearings. Drums are available in 3” diameter. Alloy end caps are heavier than the polycarbonate end caps found on the Challenger series, creating more momentum in the rollers and an increased coasting effect. While the polycarbonate end caps of the Challenger series are high quality and built to last, the Alloy end caps maintain momentum better and are even longer lasting.
The
Flywheel
is a simple, heavy device to add rotating mass to your Kreitler Rollers. Running off a belt connected to the rear drum of your rollers, the Flywheel creates a more natural road-like feel. Getting up to speed takes a little more effort, and momentary interruptions to your pedaling do not slow you down as much.  There is also an increase in resistance associated with using the Flywheel, due to the belt friction.
