Would you suck that up? Maybe I’ve got a different perception of service levels that you should expect?
No, don’t accept it.
Your contract is with whoever you bought them from – it’s down to them to sort it out.
I’d start with them and explain you’re epxecting to ride your bike int he meantime and what can they do in terms of either replacement or loan forks as the ones you have are clearly not fit for purpose.
One quick Q: have Fishers actually got hold of the forks and confirmed your diagnosis of the problem or are they workign on your ‘it’s broke and needs replacing’ diagnosis?
