I have a Trek MTB with Bontrager SSR seatpost ( I believe its aluminium). Its almost 3 yrs old.
When I was adjusting the height of saddle, I got some fine black powder on my hand (small amount) from the seatpost.
This was more than a year back.
a) Should I be concerned about the powder on the seatpost?
b) Is lubing seatpost enough for its maintenance?
c) where should I apply lube for the seatpost?
d) Can I use automotive lithium grease for it?
