>>1733010it pisses out. bike is from the 60s but its old tech.
found a manual from 1927, it says to oil with Bone Oil every 100km (does my LBS sell that? kek). the coaster brake should be oiled before every steep declin to ensure good braking.
it also says you should clean the bike with "volcano oil" (probably crude lol) or gasoline.
tfw no 1920 steel bike with drop bars, imagine riding gravel in the 20s
