Anyone use the Kreitler flywheel with their rollers? Is it worth the money?
Frankly, I don't understand how anyonecyclinseth

uses rollers without the flywheel. People say you shift into a harder gear, but then you just spin the barrels faster. There isn't any inherent resistance to rollers themselves.

Also, anybody who says you can't really hammer as hard on rollers as you can on a trainer either isn't working hard enough or hasn't figured out how to ride rollers properly.

In answer to your question, yes.

I dont have a flywheel attached to my rollers, but I'd like to comment on the "inherent resistance to rollers." There is inherent resistance between the tires and the drums (called scrubbing i believe) when the tire deforms against the drum. This is the major cause of the friction, and the reason why smaller drums give more resistance. There is definately an increase in resistance associated with shifting to a harder gear.

With that said, in my experience, in 53x12, you can get a decent amount of resistance, but not some vomit-inducing amount of resistance. Of course, I mostly just use the rollers for easy zone 2 technique spin sessions in bad weather...

Do you actually ride rollers?Kerry

Are you saying that the effort of riding rollers is independent of the gear/speed? Not on any rollers I've ever ridden! Do you have some that behave like this, or are you just repeating a myth, like the "you'll shoot across the room if you come off the rollers" nonsense?

I've got the 2 1/4" Kreitlers and I can tell you that there absolutely is resistance! I can push it until I come close to passing out on them and I don't own the flywheel. From Kreitler's web site:

Originally designed for the US Cycling Team (at their request), the Dyno-Myte features 2.25" diameter drums (15" wide) to provide a tongue draggin' load.
Yep. Poly-lytes here.djg

A little easier than the dynos, and definitely harder than the challengers. Seems like work to me.
