Cadence?
Gear ratios?
Walked the doggie today, and called in at the pub is our habit. He likes it, and so do I!
Couple of beers (honestly) and a chat with friends.
Mate of mine had a stroke some time back, and he is/was a cyclist and has recently managed to get his bike sorted ready for riding.
Excellent!
He asked me, in his difficult-to-get-out words, what gear ratios were. He would often say these days, that he's "lost knowledge".
I asked what chainrings he had and what his cassette sprockets were.
He couldn't cope with the questions, and had no idea.
I spent ten minutes or more describing gear-inches and also distance per rev of the cranks in different gears, and Penny-Farthings ......... but he wished he'd never asked!
He has issues after his stroke, and has difficulties in comprehending, though before his stroke, he would have completely understood.
Other folk in the pub - all non cyclists - were listening and also amazed about my explanations and my patience with him.
Later, another mate came in who is a late-comer cyclist, though an eBike rider. He had no idea about gear ratios either, as it doesn't matter to him.
Are we gear ratio aficionados a dying breed?
I spent years/decades with different chainrings and sprockets getting my ratios correct for the rides and the commuting I was doing.
Some folk don't, and haven't any knowledge or experience maybe.
