|   anyone with a *silent* drivetrain? | joe friday
Dec 21, 2003 11:30 AM | | i'm talking about NO noise? my chainline is only 0.5mm off
and is all new and the same size, but it makes a 'rattling'? noise. it doesn't seem like it would be from the chainline, i'm wondering if the chain itself just has
a resonant frequency? it's an aluminum frame so maybe that's
possible? any help? thanks!! |
| What size chain? | Dave Hickey
Dec 21, 2003 5:10 PM | | I've noticed a 1/8 BMX chain was much louder than a road chain. |
| One idea........... | Len J
Dec 22, 2003 7:43 AM | | is to check that the cog is straight up the chainline, centered in the rear dropouts.
I have noticed that if I don't get my rear wheel perfectly centered, the chain "rattles" as it crosses onto the cog. I have begun to notice this noise on other riders bikes, I always want to stop them and fix it for them.
There is a "sweet spot" where the cog is perfectly aligned with the chainline where the noises disappear.

Dec 22, 2003 11:57 AM | | it's a 1/8" Izumi V chain, i will try to get it centered,
I thought it was but it's not easy to know for sure--
I guess i'll know when it stops rattling :) |
| If, like mine, the chain line is less than perfect | dzrider
Dec 23, 2003 9:03 AM | | Should I continue to compensate by using the dropout screws to aline the cog with the chain? It's quieter if I do. |

Dec 22, 2003 12:04 PM | | I think mine is silent, but I cannot be sure, because my seat spings queek. I agree with what the others have said. |
| Mine is | Dave_Stohler
Dec 23, 2003 9:06 AM | | My chainline is dead-nuts on (both on fixed and free sides), and I'm using a KMD track chain-the cheap one that costs $15. My ring/cog combos are as follows:
fixed: Salsa 45 and Surly 16
free: Shimano 600 and Shimano 18 BMX
I regularly scare the bejeezus out of people by silently overtaking them on the local MUT. My big 38 Nimbi tires are also very quiet. I sometimes scare crackheads down at the local park by approaching silently under the bridges there. The bike cops really should look into riding something like this! |
| 1/8 chain, 3/32 cog would do it. | Alex-in-Evanston
Dec 23, 2003 10:02 AM | | Since it doesn't fit snugly on the teeth, the chain will "pop" back and forth, alternately resting on the inside plate and the outside plate.
It's very annoying.
