Hey - Now this is something to think about - I have Steel on Aluminium all over my bike and in a few places Brass and Copper on aluminium and all the mix - But technically speaking this is a pipe fitters nightmare - No no no says the pipe fitter - You must consider compatible metals at all times - Well I'm thinking strength and malleable abilities and just keeping things clean and looking nice - Not really considering their Galvanic factors of erosion/corrosion when using the three in a semi-electroliytic environment - Wow- Now its looking interesting - I went and checked my bikes and can't really see any unusual corrosion or erosion from the mixes - But my bikes are stored indoors in Central Texas - Could this be a real factor for consideration when near the coast and in a salt air environment...

(Hope to ride again on Thanks Giving)
