Alloy Rollers- Aluminum Drum Bicycle Rollers for Indoor Resistance Training While Enhancing Your Balance and Pedal Stroke Made in The USA.

I did a lot of research before purchasing this roller, and I am exceptionally pleased with this product. The Kreitler rollers are very well made (in the USA), the design is simple, and appears to be very durable. Although these are expensive, what you get is quality and I feel this roller set will probably last me for the rest of my life. I have been using this product almost every day for the past two and a half months, and I love it. It is the closest feel to road riding you can get for riding indoors, and it has raised my fitness while being stuck inside for the winter. I should mention that I changed the tires on my bike to trainers (instead of street tires) to ride on the rollers, and the only noise I hear while riding is from the drivetrain on my bike. I like the ability to fold up the unit in half and put it away when not in use. If I had one critical comment, which is not a fault of the roller, but my inexperience. There is definitely a learning curve getting used to riding on the rollers. The first few times I attempted to ride, I flew off the sides. But after several sessions, it was no longer a problem, and now I absolutely fly on these! Overall, I could not be more satisfied with my Kreitler Alloy Rollers.
