I am currently giving Sigma Sports the benefit of the doubt over my warranty issue but would like to explain where I currently am and why, as a FE/HE Lecturer in Customer Service, I find their response "warmish". I bought a Cinelli Zydeco in June 2020 which is still under warranty. During a service, the press fit BB on the drive side fell out, literally fell out. Sigma asked for photos which I duly sent and as they quite rightly stated to me without inspecting it they cannot be sure what the issue is and who the blame lies with, including me! Apparently it could be rider error. Therefore I have packed a box (more cycle photos required) and they have arranged for a collection. If the frame is faulty then I am not sure what happens next as Sigma were more keen in telling me that the opinions of other professional cyclists and shop mechanics on warranty issues was worth not a jot. It was suggested in one conversation that I "stuck" the BB in place with some fixing paste! A short term fix one would think that would probably rear its head again at some point and then me be out of warranty. So if Cinelli fitted a potentially faulty BB to my frame and then shipped it to Sigma Sports, for some apparent reason that is now my fault and if the BB is faulty, Sigma will ONLY CHARGE ME for the part....!! However, I would consider Sigma Sports to be a great company. Their website and products are next to none BUT I do find their response to warranty claims slightly odd. Trying to arrange a collection is also proving difficult and it was also pointed out (rightly I guess?) that until the bike is safely with Sigma, anything that happens in transportation is guess what........!! Yep, my fault. Over £2500 on a new bike under a year old... as I said the verdict currently out and don't let that put you off buying a bike or anything else from Sigma, but I'm keen to understand what will happen next....And I will update here. Communicated both email and telephone.
