I got a couple old gt racing bmx shainrings around they are 110mm I will see how many teeth they got when I get in my bin next mmmk

Yeah sure, although I'll want them to be new, or not worn down. I'm out of town for a week starting now, but PM me if you find anything.

Oh, does anyone know if Tron's option is a rocket ring (i.e. low quality) or good quality? It's looking mighty nice, although funny how it says "Fits all 1/8 and 3/32" chains." So I'm guessing if it fits them all, it's a 3/32".

Well, others have covered it, and this is only my second fixed gear, so I'm no expert but this is what worked:

1) Chainline, chainline, chainline - that's #1 because of the number of moving parts, and the amount of stress they are under, they will be noisy as he(double hockeysticks) if off even by 2mm
2) Spend enough on the components - you don't have to go Phil, but cheaping out will get you noisy stuff
3) Lubricate the chain regularly - I like white lightning

HTH

to reiterate, chainrings that aren't perfectly round cause slack in the chain during part of the revolution, which, when you're spinning along, tends to oscillate (sometimes violently), creating some noise and noticeable vibration.

clean the **** out of your chain, fix your chainline, check the chain tension, and replace the chainring if necessary.

white lightning & other wax based lubes, in my experience, can leave residue that makes cleaning a little more of a pain in the ass.

the first one is a rocket

the second is sugino

sometimes you can find mtb chainrings that are 110bcd also that don't have any ramps or pins as well



found my old bmx rings they are all silver they are also 43 and 46t just shoot me a pm when ever you are in sacramento and they are yours if you want em
