Just purchased a Trans X ahead stem to go on steel steerer and suddenly wondered if I need to grease the steerer or to use CopperEase ? Not sure if the Trans x is aluminium ? If I don't grease or put copperease on will they fuse together ? Many thanks for your help
No don't grease it, the idea is the stem grips the steerer, the last thing you want is it slipping. You could use Copperease to stop any corrosion issues, but I've used a similar set up (steel steerer and aluminium stem) for years with no copperease and no issues.
