this is bobbins. If the customer builds it the shop has no responsibility / liability for anything that could be wrong because of the build.
That’s not my point. Quite a number of bikes come out of the box with ‘issues’. Stripped threads, scratches/scuffs to the frame, marginally incorrect spec etc. These can be warrentied quickly and easily by a shop worker. If a customer comes to me and says ‘I took it out of the box, and it had this massive dent in the top tube’, how do I know he hasn’t just dropped his hammer on it?
Who do I side with, the customer or the bike firm?
Not worth the hassle.
