By fork service do they mean the full shebang or just the seals? Are they doing all the o-ring and the damping etc. if full thing say 80.
Bleed ~30
brake pads could be 25 each end brand retail.
so 290 for changin the transmission parts and time.
seems steep to me, but I do all my own stuff, this is why.
In fairness they would have maybe also done other things as part of the service, wheel true and bearing change. What was the standard charge for a service?
did they say what they were doing as standard?
In short unless they’re doing other stuff they haven’t mentioned I would be saying no thank you, pay them for what they have done, and go elsewhere… I can’t find maths that makes this work for the work you’ve described tbh
