I’d say give it a decent chance.
Being tall, I rarely get to test bikes before buying. I bought a Kona Honzo (similar geometry to the Process 111) a few years ago and thought I’d made a big mistake. It took me a few months to realise I hadn’t, and just needed to be a bit more dynamic on the bike.
I then bought a Liteville 301 (slack, but rather short on reach) to replace my suspension bike and couldn’t get on with it – I gave it a good chance and changed various bits, but after having a long (reach) bike, it never felt right. I replaced it with a Process 111 and all’s good again.
For me, the longer reach/front centre gives me confidence. I ride mainly in the Surrey Hills/North Downs (plus annual Alps trip) if that makes any difference.
