As many in this forum I own a 90´s bicycle and modern bicycles. I´m still scared to go down stairs with any XC MTB like my Marin or the Specialized stumpjumper HT from 2006, but I feel quite confident to go down with my commencal Meta with 160mm travel, very confident.
Soy that guys, with their 80´s treks are pretty good, amazing ride skills. And now I apreciate more with the moderns slack bicycles that do all the job.
