Old school steel here. But then, I was already in my 40s when these were new.

1997 KHS Summit-X hardtail. Bought this in 2010 on Craigslist. From the condition of it and the rest of the bikes in the garage, this was only ride a couple of times around the cul-de-sac.




I rode it on the trails a bit, but mostly bought it to turn in an Xtracycle cargo bike.




Then I bought a beater Trek 830 on Craigslist for $60. I used it for roads and trails when the weather was crap. My daughter has it at college now, so if it gets stolen, it won't bother me.

Then I found the bike I really wanted on eBay in 2013, a 1993 Trek 970 SingleTrack; Trek's top of the line bike then, and sold for $900 ($1500 in 2016 dollars.) Like new, barely used (complete with Trek branded tool bag and working cyclocomputer) for $400 shipped.
