Steel - Aluminum corrosion
Steel - Aluminum corrosion
I have a steel frame and I'm looking on getting aluminum parts (eg: seatpost, headset etc)
Is Corrosion a concern?
Will I need to service the bike more frequently?
Is lube between the two metals going to make any difference?

You are creating a galvanic cell so if it gets wet you will definitely get corrosion. Luckily the aluminum parts are the ones that are more anodic and corrode so you wouldn't be ruining the frame.
If the lubricant isn't conductive it would at least help.
