Two broken teeth in Shimano 105 crankset I have just received my new 105 7000 cranksets from a reputable seller in Aliexpress and I believe there are two broken teeth perhaps cause by mishandling of the shipment company or poor wrapping of the groupset components. Do these affect the performance of the shifting and do I have to bother sending these back?
Measured the rest of the teeth are around 5mm and these 2 are 4mm now.
If it was mine and I damaged it riding, moving, storing etc. I would try to de-burr the edges and see how it shifted. In your case any modifications you make means you own it. Contact either the shipper or the vendor and forward the pictures to their claims dept. If you exhaust all avenues and are stuck with it, try repairing it then install it. If it works  to your satisfaction monitor it for premature wear. If the shifting seems less than optimal replace just the large ring and it should work like new one.
