My 2019 Himalayan has only done 1000 miles. I have noticed specks of rust on the spokes which are difficult to remove. I thought RE used stainless spokes but these look more like chrome, which I thought was a no-no because of embrittlement? The spokes are magnetic but some stainless is magnetic so that's not a decider. Does anybody know if they are or not?
Bucanan's Spoke and Rim which is the premier and oldest rim wheel builder in the US lists spokes in stainless steel, chrome plated carbon steel and bare carbon steel. Exactly what's on our Himalayans I couldn't say, mine show no rust, but I don't ride it if the roads are salty, and give the wheel a going over, including cleaning the spokes on a regular basis.
My guess would be carbon steel with a protective coating, maybe zinc maybe nothing, but honestly, I'm really not certain, mine dull and turn gray if I don't keep after them, so I doubt they're stainless. If they are it's a piss poor grade.
