Be careful when changing some bolts. I know its boring but certain bolts need to be high tensile.
Ya dont wanna be putting ali bolts on brake discs for instance. Fork pinch bolts, brake disc and caliper bolts, and sprocket bolts all should really be high tensile.
And if your using stainless bolts going into aluminium, copper slip the threads else naughtyness happens.
Stainless is ok but its also heavy, and they all add up.
I would love to get them bolts with the washer 'moulded' into the hex head but am struggling to find them
