I’ve had X-Fusion forks in 26 guise – Slants and 29er – Traces. Both excellent forks with noticeably better damping and stifness than the revelations they replaced. Also had Devilles (in 26 flavour). The Deville is an awesome fork, somehow super plush while having fantastic damping. Light and stiff and pretty easy to set up compared to some forks with High/Low speed damping adjust.
I liked the X-Fusions for their simplicity and performance at a price – at the time – way less than a BOS or a Pike. Having had 650B pikes for three weeks on the new bike, I’d have to say they are noticeably better than the x-fusions, and I certainly wouldn’t feel a BOS would be a massive upgrade.
Hadn’t realised until reading this thread how many 160mm forks there are. Enduro eh?
