Pretty sure I’ve told this story before. As a teenager I put 115s (from a small child’s bike) on my cheap mountain bike which had 26" wheels & originally 165mm cranks. Was weird at first, took a few rides but then got used to it. Then got back on my road bike which had 170s which then felt weird but of course in the opposite way. After a couple of weeks of alternating, the weirdness only lasted a few minutes at a time.
Wish I had a photo of that bike, it was just absurdly silly.
