I have a bike that has been sitting in the outdoors for 3 years. I
bought it from the guy-a ganwell pro. Hand made(?) japanese bike, all
shimano105 parts. there was some water that drained out of the small
holes in the frame
is there some way to treat the inside of the tubing to prevent or slow
down the rusting? I heard on this group of a spray that you fill up the
insides with.
the frame is steel.
