A cycling desk / Zwifting with a split keyboard

I think with proper cycling posture you can take the pressure off of your wrists.

Use your back and shoulder muscles to support your upper body and arms, so that you can ride with elbows bent. If you can bend your elbows, you can avoid pushing on the handlebars for support. That will make for more comfortable wrists with or without a keyboard.

Funny you referenced Sheldon. He's like Knuth of cycling.

The industry will keep shoving down your throat their new "advancements" every year, but at the end of the day, bikes hasn't changed a lot, and the common knowledge will remain the same.

Unsurprisingly, core strength is a big part of cycling. It's a good test to lean down in a more aero position and lift your hands slightly off the bars and see how long you can hold it.

so less pressure on your wrists while typing would be quite the core workout over an extended period of time.

I don’t know that I completely agree. Yes, many elements are similar, but a carbon road bike with disc brakes, electronic shifting, deep wheels, radar, a computer and tubeless 28mm or 30mm tyres is an actual wonder to ride. I’m justifying a truly silly spend, but when I get on an old bike or a rental, it feels like stepping back in time.

Maybe we need a TT bike keyboard?

Yeah, I have an old Panasonic Sport that I'll take out with some older fellas who live near me in rural Kentucky. They have nice carbon bikes with all the bells and whistles. It's night and day how much harder I have to work to keep up with them

Yeah I learned this lesson the hard way when after a century ride, my left hand ring finger and pinky went numb for almost two days. Started making sure I had my elbows bent and used my core to keep myself more upright.
