im not really that bothered about, i was just wondering if zinc was more prone to cold forging to the aluminium in the stem (or something like that), than the regular black oxide coating. the stem came with zinc coated bolts is all
i grease the shit out of all the bolts on my bike but this thing was not budging at all, i guess i must have overtightened cos it launched out of there when i sawed through the bolt (the head is still in my lounge somewhere, i dont know where it ended up it shot off that fast).
