Easy course, NTM. 2 Strava top 10 results descending. Went from 25 PSI from the old (2.3 DD) setup to 21 PSI (2.5 Exo CC). No rim hits. I did feel the rear end getting a little squirrelly in rocky turns. I was faster overall.
Climbing the loose fire road had noticeably better grip. That could be due to tread alone.
