The Fox chassis is better than the RS IMO. Although the Lyrik does have a bit more meat on it, so might not suffer the creaking issues like the Pike.
I’m not a fan of the damper in them though, could never get it set up right, and it was the most unreliable fork i’ve owned.
But them I don’t think i’m much of a fan of closed damper system forks, they all seam to have niggles in performance, to chase ever lighter goals. Personally I think if the Lyrik chassis proves to be tough, an open bath, proper tunable damper in it (like an Avalanche) would be the best choice. Until people get some miles in it & it proves itself, I would stick with the 26 & do the same.
If you want an off the shelf fork, i’d rather have a Lyrik over a 36, having replaced the latter with the former.
The new BOS fork is coming out soon in 170mm if you want something leftfield?
