Pure Bike Oil
"At last! A see through bottle!! You need never run out again! Great sized nozzle, and perfect viscosity…drips easily into cable outers with no spill over, just take your time and do it drip by drip…I ran the inner through my fingers which had some on to lube the cable up a bit and i've got smooth slick shifting and braking. Even though it's thin, I can see the bottle lasting a while, as it doesn’t need a heavy application…..and as it's Pure, it's dripped all over my utilty room floor but I’m not worried about the cats licking it."
