Sent my transfer to TF tuned for a service, ended up buying a bike yoke revive instead and now have a complete 150mm drop transfer in pieces….

How much is reasonable to expect for it? Would it be more economical to pay for it to be rebuilt to sell?

Sorry! Unsure what makes sense to do

I probably wouldn’t buy a post that had been dissassebled and not serviced.
Over here a factory service is 135cad (~£80)
I can’t however understand why it’s in pieces though.. did you ask TF to stop? Presumably disassembly and return shipping isn’t free. Why wouldn’t you have them finish off? Or did they tell you it needed a bunch of parts and are waiting on approval to continue?

They stripped it to service and suggested it needed new parts for a marked shaft at £50 on top of service cost – approx £90. I wanted more drop anyway so went with the revive instead but am thinking the cost of the service and parts would not be covered by sale price.
