I’m a hearty #2 man, myself. I’ve joked forever about “having a salad” when presented with an opportunity to upgrade to newer, lighter bike parts. Semi-rad uses some math to further the case for GI regularity.
If your full-time job is something other than “professional cyclist,” I think you should save the money you’d like to spend on the newest ultralight bike frame, get something cheaper, and just take a dump before you go on your ride.
