Posting in the 65+ thread automatically qualifies you as Old School. Regardless of any other consideration.

Bikes - I ride with tubes in all my tires. I call it Smart School, maybe old, too. Skinny tires are what? I ride the spectrum from 22mm - 32mm (clincher + tubular) for road bikes. Probably replace the 22m tubulars with 24mm, when I wear those tires out. On smooth roads or almost any of the paved bike trails = 22mm is just fine. 25-27 most roads. Hard packed 'off-road' trails feel most secure beginning at 30mm (sometimes a bit muddy or extra gravelly in spots). 32mm Schwalbe Marathons on the road tandem. Heck, on the 30pound e-road bike 38mm RHerse (Barlow Pass). 2.1" Billy Bonkers on 26" rigid mtb. Butt, ... I hear fat tires are moving to 3" - 75mm at 8psi and riders swearing it's faster and they feel better at the end of a ride having had zero vibration. . That's progress.
