It's been a strange journey for MTB geometry over the last 20 years.
In my Kona's case it was actually a 17" full length seat tube, 66.5°HA, 73.5°SA, and 24.6" ETT. Yeah, it was heavy and 170mm of travel... But I've ridden worse geometry that came out much more recently.
Those Knolly guys sound like visionaries... The original "forward geometry" and real 1x climbing setups.
