This thread got me thinking. In the 60s I was a paperboy with a rural route. Lots of bike riding every day on my Huffy. I also caddied at a golf course on the weekends and that required a ten mile ride one way and back again. I did all that riding a 35 lb bike with 26" ballon tires and I probably weighed less than 90lbs myself at barely 5' tall. How did I do that on a bike that wasn't "road, gravel, mountain or CX"? At 13-14 years old...there is no pain. Except when Charlene wouldn't even look at me...I suffered greatly.
