This wasn’t my Sovereign was it? 😀
I ran a Lyrik air 160 for a while, that was fun for bombing the downhills but turned it into a bit of a barge.
More recently I have run an RLT Ti Rev at 140… this transformed the bike and made it into (imo) the all around trail slayer it was, still stable on the downhills with decently wide bars (I was down at 740 in the end with a 65mm stem, any shorter and it got twitchy at speed through rough stuff), but still felt very stable jumping and cornering.
I would say that if you’re going to be riding anything chunky off road then go for a 20mm through axle if you can, the 32 stanchions do flex noticeably so you need to preserve as much rigidity as you can, the new wave of 34mm forks would be perfect (X-Fusion Slant, BOS Deville etc).
They’re amazing frames and when I’m a bit more solvent to have 2 bikes I’ll be buying another one or something similar.
