About 30+ years ago I bought my first road bike. It had an old (used) Brooks leather saddle on it, whose design probably dated back to 1900 AD. To anyone who hasn't seen these,
they look like a they were inspired by horse saddles, but tinier. The leather is rock hard, but once they get broken in are surprisingly comfortable.
Nowadays the saddles you see in shops are all high-tech, lightweight creations. I had to search, but found some ads for Brooks on Amazon. So: does anyone use them? Or are they outdated and anachronistic?
