Kreitler 4.5 Alloy Rollers
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.
If you add the Kreitler Headwind Fan, you will have the widest range of roller workload that Kreitler has to offer.
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.
I have this version of the kreitler rollers. I also have the Headwind accessory. I most commonly ride it without the Headwind resistance unit as I can usually get enough resistance out of it for winter indoor training to simulate typical road riding conditions. The headwind unit can really take the resistance up if you need more of it. Makes you much more aware of balance, steering input and pedal power balance.
