chain oilers
I knew that some motorcycles had a chain-oiler on their swing arm.
First you filled the hollow swing-arm with oil through a cap on the top. Then you adjusted a screw to let the oil dribble out a plastic or rubber tube onto the lower chain run (at least until dust and mud clogged the drip tube). *** But I didn't know that some bicycles had a top-run chain-oiler on the seat tube, before and after World War II, or that pros used them. Single-speed flip-flop 1936 Gloria with chain-oiler built into frame: http://gallery.mac.com/bbattle/10015...ankset/web.jpg http://gallery.mac.com/bbattle#10015...&bgcolor=black Here's the same model of chain-oiler on a 1935 rear derailleur bike: http://www.wooljersey.com/gallery/v/...geViewsIndex=1 A 1937 Claude Butler British bike with chain-oiler: http://www.classicrendezvous.com/Bri...r_Warnick2.htm http://www.classicrendezvous.com/Bri...aud_butler.htm *** Now that you know what the little built-in chain-oiler dingus looks like, you can see it here in 1927: http://www.wooljersey.com/gallery/v/...View sIndex=1 This chain-oiler one is turned and ready for use on a 1955 Chemineau: http://sports.webshots.com/photo/275...27374678oBfTQi http://velo-orange.blogspot.com/2007...chemineau.html *** 1951 Tour of Flanders, a clamp-on chain-oiler with external reservoir: http://www.wooljersey.com/gallery/v/...geViewsIndex=1 The chain-oiler is next to the seat-tube shifter and looks almost like a miniature gonfleur, but the real gonfleur is on the down-tube. *** I suspect that the chain-oiler, like goggles and tire scrapers, vanished as the dirt roads were paved. Nowadays, chain-oilers are more common on chainsaws. Cheers, Carl Fogel |

You can still buy them from Old Blighty, where corroded chains are evidently one of their many blights: http://www.scottoilerusa.com/ Oiling the chain through orifices in the derailleur pulley is rather ingenious.

Well, I'm all for anything that "extends drivetrain life by 2 to 7 times, increases efficiency, and eliminates over 90% of drivetrain maintenance." -- Mike "Rocket J Squirrel" Bend, Oregon |

Chalo Dear Chalo, Selling a gallon of "Scottoiler Active Fluid" for about $200 is even more ingenious--twelve bucks for 250 ml! Applying about 2 ml to each roller on a ~114 link chain would use up a $12 bottle, but the company claims that its scheme saves money. At that price, I'd apply the "Active Fluid" by hand with a Q-tip to individual chain rollers instead of "squeezing the Scottoiler squid" to pump the precious stuff through the Rube Goldberg contraption. The stuff looks like orange juice (~$5 per gallon): http://scottoilerusa.com/images/reservoir%20001.jpg Somehow I doubt that we'll see Scottoilers used by any pros. Dr. M. Kidd of "Herriot-Watt" University's claims that a dry chain loses 13% of its efficiency: http://www.scottoiler.com/UserFiles/...w_it_works.pdf Kidd's claim would be news to Spicer, whose chain test showed that a degreased chain's "efficiencies are essentially the same as those measured for the chain in the re-lubricated condition." http://www.ihpva.org/HParchive/PDF/hp50-2000.pdf "Herriot-Watt" is usually spelled with only one 'r'. A search for the details comes up empty, but shows that Kidd's thesis is indeed out there somewhe http://www.google.com/search?hl=en&l...+efficiency%22 Darned hard to find a photo or diagram of the Scottoiler beast on the site. Here's a nice photo of the oil tube wound around the rear derailleur cable at the bottom of this page: http://scottoilerusa.com/dirtrag125_p060.pdf Cheers, Carl Fogel |

Now why does this device not come under the warning "do not lubricate a dirty chain, it just pushes dirt to where it does the most damage"? |
