[Closed] Knocking Fox Float DPS

Hi all

I'm reaching out for a little advice. I have a BMC Speedfox 03 with a Fox Float DPS rear shock.

it started knocking on compression a few months back so had it in to the local shop where they (apparently) replaced the flange(?) where the top of the shock joins the frame.

when I picked it up there was still a slight knock. the mechanic said "that's normal" but I'm pretty sure it wasn't like that when I bought the bike.

so my question to you folks is - is it normal or should I throw this back at them to fix again? heading to the Alps week after next so I need this to be right before I thrown myself down a very bill hill 🙂

thanks in advance
