30 years ago I was given a pair of slicks for my Ritchey mtb. Was quite surprised at how well it rolled.
younger and faster, a number of the racing set were despondent when they could not drop me on a hill and were dropped by me.
I stopped at a market and they were even more bummed when they pulled up and realized that my bike was 8lbs or more heavier too.
just added insult to injury.
