If you are running an 1/8" cog in back and 1/8" chain on a 3/32" chainring on the inside of a road double like i was, you really should spend the money and get a shorter bottom bracket to get a straight chainline and 1/8" chainring.
Its like night and day. Everything is so much easier and it feels like no power is being wasted.
I still have some clickity clacking i need to remedy though. I should just get a new chain and see if that helps. After seeing what happened to this white chain I don’t think its a good idea to run a colored chain since the paint or powder coat disintegrates and basically becomes the same as dirt in there.
Nah dude. Me and Zelah spent the other night filing down his chain ring and adding in some secret lube (read: semen) that has not only allowed a 3/32 chain to be silky smooth on his tarck drivetrain, but has also inadvertently created a perpetual motion machine. Now we have all our group rides on the freeway and drag race rice rockets for a living.
There are 3/32 and then there are 3/32 chains… I mean, chains for a 5-speed cassette and chains for a 9-speed cassette are sold as 3/32, and obviously they are different widths. Probably also different 1/8 cogs and chainrings are slightly different in thickness, so I guess a wide “3/32” chain could fit on a thin “1/8” cog. I’d guess its rare though, if even possible.
3/32" is the measurement of the internal width of the chain. Up until 9 speed I think they just made the external width narrower (thinner plates and rivets). They are still 3/32" chains. 10 speed has a narrower inner width, and god knows what the new Campy 11 speed chains will look like.
when i first built my bike and was running the 3/32 ring up front it was also smooth and silent for a couple days and then i lubed it and a couple days later i started hearing noise from the cog. now that i have all 1/8 stuff i hear noise from the chainring. i miss the silence. i thought this new sugino ring would kill it and now its the cause.
this subject has probably been beat to death on bfssfg but i dont feel like searching over there right now.
the tension is pretty good, about a half inch of play. i’ll just try recentering the chainring. i hope the spider isnt slightly bent or something…
Yeah, I was talking utter bullshit. Sry. Though I have a KMC “6-speed 3/32” chain that’s 2.5mm inner width and a Shimano “9-speed 3/32” that is 2.3mm, the difference is minimal when compared to 1/8" (theoretically 3.175mm but my KMC measures 3.5mm) (can’t think in inches)
speaking of lube (sort of), thats all my chain needed and now its silent again except for the occasional click which is either from my really crappy pedals, chainring bolts, or crank bolts, all of which i am going to grease since i forgot to do that. i ALWAYS forget to do that. it sucks. i dont think i greased my cog either now that i think about it
