Miss Lorette Burke removes pants on wood rollers, chrome Paramount, 1948:
That Classic & Vintage enough for you?
Hard to learn? Dan Henry (yes, THAT Dan Henry) could strip to his skivvies while rollering, a skill he would demonstrate at cycle rallies.
They might be old school, but I'm unconvinced that rollers are obsolete. I go on early spring rides and see strong riders lurching side to side, stomping at the pedals and think, 'You spent the winter on a fixed trainer, didn't you?' So much wasted power!
My set is approaching 40 years old, the Kreitler economy model of the day with large diameter full-polycarbonate rollers. I ordered a new drive belt last year - I mean, the world's simplest bicycle part but still pleased I could get one.
