Does anyone know if you can upgrade a Sid Ultimate SL 110 fork and Sid Luxe 110 Shock to Flight Attendant?
From what I’ve heard… Fork yes, shock no.
What bike? The fork yes, but shock is bike specific.
You might want to double check on the fork. When I spoke to sram about my sid (35), you could only upgrade the newest chassis (I think it was the “D” version) to the flight attendant damper. The SL may not have any chassis limitation, but definitely worth checking before jumping in.
As others said, the shock is bike and FA specific and there is no way to add FA capabilities to a non-FA shock. But I know there are people putting FA shocks on unsupported bikes, sometimes having to get aftermarket yokes to make the size/travel work. The shock wouldn’t be tuned specific to the bike, but the FA control logic/behavior isn’t bike specific as far as I know.
