@howard SiSL2 crank with BB30 bearings pressed into metal derlin cups in the frame. Quite a bit of wear in the cups which can been seen where the black anodizing has been worn back the the silver machining so assuming this is the culprit of the creak. Bike has been with another shop a few times over the past 18 months without resolve and would like to solve this once and for all for a new customer.
