Working out in the winter

I don't have a large flywheel for it. Is that an easy swap and what are the benefits? This particular trainer is indeed a Rock-n-Roll Kinetic trainer -- I love it. A friend loaned it to me when I broke my foot, and it never left.

Agree on taking care of our knees!! I raced for several years and I'm starting to feel it in cold weather. Aging sucks.
It's been a few years, and I'll try to remember to get a picture or three when I get home this evening, but from that I can remember it's a simple install: Place it over the small/original wheel, and tighten down the center wing nut (or maybe it's a bolt).

The main benefit is that you're not constantly trying to "restart" the wheel, if you get my drift. It's hard for me to describe, but with the wheel mounted-up there's more "mass" to keep it spinning, and as a long distance rider I found that preferable. (Back in the Day I thought nothing of doing a century, or even a 150, with little prior notice). However, as racer (ex- or current), if you do wind sprints/intervals on your trainer you may find it annoying, as the flywheel effect will work against you...if that makes any sense.

Too bad you're a half-country away, otherwise I'd be happy to send mine out for you to try.

(Edit: Then again, it's not that heavy...., and I'm not using it...)
