Do the newer Lyriks not come with a 150mm option?

Failing that is there a 150mm air shaft available?

I’ve tried looking and can only assume it doesn’t exist.

According to the RockShox SPC 2018, the 2018 fork is the same as the 2017 in respect of the air shafts…..

“Air Shaft Solo Air – PIKE (160mm 27.5/140mm 29), Lyrik/Yari/Pike 29+ (150mm)”

Part number – 11.4018.026.001

(As you can see, same as a Pike 160mm for 27.5 fork so should be readily available)

edited because I checked on the importer/distributor website and they are listing the 150mm model…ZyroFisher 150mm Lyrik

29″ comes in 150mm, no 27.5 option, but can be sorted with an air shaft:

Yes – that’s the same air shaft that I’ve already given the part number for !
