I've been far from dilligent about cleaning and oiling. Indeed, oil is unhelpful, the links are sealed and oil just attracts dust. Thanks for reading, bob prohaska |

Actually there is a standard 1/2" x 5/16" sealed chain manufactured in a number of widths ( ISO R606, 08B-1) and while it is too wide to use on a derailer system it might work for a single speed. Certainly well enough to determine whether it would be an advantage on a bicycle. The maker describes these chains as "maintenance free, lube free roller chain". On the other hand The Complete Guide to Chain © 1997 by U.S. Tsubaki, Inc. states, in reference to sealed chains, that: "The link plates holding the O-rings are under compression. This means greater force is required to articulate the chain, and the transmitted power is decreased." -- cheers, John B. |

See http://thorncyclesforum.co.uk/index.php?topic=6813.0 where I describe just such an experiment. I've stopped using Hebie Chaingliders. They are very draggy by design, which I could put up with, are a faff to remove, which again I could put up with, but critically I've lunched two of them in normal use where the rear sprocket cover has caught in something and wrapped around the chain. I use the Hebie Chainbar now, it's good enough, looks stylish, and doesn't make a dive for the whirly bits at unexpected moments. |

I've been far from dilligent about cleaning and oiling. Indeed, oil is unhelpful, the links are sealed and oil just attracts dust. To do an O-ring chain on a bicycle would require an increased link size, in both length and width. The chain wheels and sprockets would all have to change to a new standard. Wider links would mean the end of 9, 10, & 11 speed rear cassettes. It still might make sense to do O-ring chains for "transportational" bicycles where the increased losses due to weight would not be a big issue. There have also been bicycles with drive shafts (and internal hub gearing). The "ferocious demands" of a chain are vastly overstated. Some cyclists spend an inordinate amount of time and money on chain maintenance for no real benefit, other than it makes them feel good to believe that they are doing something good for their chain. And worse, some methods of chain cleaning and lubrication that they are using neither clean, nor lubricate. Every year at Interbike you can be sure of two things: 1) there will be about 25 new creations of energy drinks, gels, and bars, and 2) there will be about 25 new creations of chain lubricants and cleaners. At least on cars, there are standards for motor oils and foolishly paying more for a gourmet oil is pretty rare. With bicycles, you must have a hundred different chain lubricants and fifty different chain cleaner formulas when all you really need to properly clean and lubricate a chain is a petroleum based solvent like kerosene, and a foaming chain lubricant which is able to penetrate between the pin and bushing. Instead, you have a lot of people with very clean chains but only on the outside, and you have them dripping lubricant on the chain, little of which ever reaches where it needs to go--it's akin to taking vitamin and mineral supplements. It is not necessary to remove a chain from the bicycle to clean and lubricate it, and in fact it isn't even a good idea to do this on the narrower chains for 10-11 speed rear cassettes. Those chain cleaning machines do a very good job as long as you change the solvent several times until it runs clean. As Sheldon wrote: "The on-the-bike system has the advantage that the cleaning machine flexes the links and spins the rollers. This scrubbing action may do a better job of cleaning the innards." At least no one seems to be doing hot waxing of chains anymore! |

Market prevails.
No more than 2500 miles HG50 ? clean every day...bottle shake with thinner..Epic or Valvo Synth/ average over the road clean conditions. but the Hebie report is AAA ! road incidents, eg the random pebble ingestion...RPI...take extra expense for longer ? chain into nowhere If belts appear in the TDF ... |

That's pretty dishonest selective quoting. Sheldon's page also says "There are several ways that people try to clean their chains. Only those which involve removing the chain from the bicycle are very satisfactory." At least no one seems to be doing hot waxing of chains anymore! Oh? I thought that both James and Frank were chain waxers? That's what I do. My method's unusual, but it works great. It does not involve removing the chain, melting pots of hot wax, squeaking after a rain, or any of the other supposed evils of wax lubrication. And BTW, it's not covered on Sheldon's site. On today's ride, I noticed the guy on the Cervelo had an extreme grease tattoo going up the entire back of his right calf. I don't get those, and I don't get black gunk all over my cogs, chainrings, chainstays, etc. -- - Frank Krygowski |
