The Zeb select with RC has an ifp type arrangement in the leg (like a basic Fox Grip) rather than a bladder damper like the full charger.
It’s better than motion control, worse than a full charger. From what I’ve read it’s not bad.
Vs your existing Lyrik it’s a worse damper but maybe not that much worse – I’m not sure if yours is the charger 2 or an early charger 2.1
It doesn’t sound like you need the heavier / stiffer chassis tbh – but if you like the look of it and it’ll make you feel warm inside everytime you get your bike out then who is to criticise!
You could just ride the Zeb and see how you get on with it – if you don’t ride it that hard you might not find the limitation of the damper anyway.
As I understand it, if you wanted to, further down the line you could take the ifp damper out and just bolt in a charger 2.1 rc2 damper to take it up to a full ultimate spec one anyway. Prob cost £300 ish – depending on what deals are available on the charger damper at the time.
