Probably a daft uestion regarding a Rockshox rear shock unit
Can you tell me whether having removed the air shock from the rear end of my trek fuel mountain bike. I was suprised that the bottom damper half was able to rotate independantly of the top half, (I am not talking about the air can unscrewing. Just when I hold the top half of the aircan end, I can rotate the bottom shaft end within the top half, I know this is pretty irrelevent when its clamped up in the bike and the eyelets are parallel to each other. But I thought they would be locked in parallel position, Or not ? I was just concerned I was unscrewing something that might come loose later on.
Thanks in advance for any advice
Apologies if this is an obvious question, but I am pretty new to MTB suspension components
