My latest "project" involves my bike, i.e. I want to perform a complete renovation of it. This involves changing rim, complete shift group, brakes, hubs, carrier etc, just keeping frame, seat post and handlebar & stem.
I wanted to start by stripping down my bike to those bare components, and while I was cleaning and oiling the seat post, I discovered a horrible stench from within the frame. This smell is best described as sewage ( hydrogen sulfide is the chemical behind that I believe).
Since that aluminum frame is roughly 15 years old and heavily used, I now wonder whether this water in the frame causes a risk to the frame?
PS: Please do not discuss whether do-it-yourself is appropriate here, building up the bike from its parts is part of the fun.
