horrible rubbing

Jlittle · April 18, 2008, 08:08:26 AM

Ok so 2 days ago, i gave my chain abit of tightening. I hop back on the bike to take it to my Gmoms. I hear and feel this rubbing. In my experience with cars it feels and sounds like a warped rotor... It sounds like it comming from the front tire, and it only started after i tightened my chain or atleast noticed it after. Well it was alittle less apparent today but it still there. Ive already took my back end and realigned it and didnt do anything thinking maybe it was the rear tire misaligned i visually inspected it and saw nothing. Now im starting to think its internal and kinda getting worried. =X

Does it sound like .... grrrrrruch ... quiet, grrrrruch ... quiet, grrrrrruch ... quiet ... and seems to increase with speed till ~15-20 and then fades away fast ??
Maybe your chain is warped.
You adjust your chain and you eat the bearings in your fornt wheel, sounds rather far fetched to me.
Cool.

yea my chain is raise on one side alittle actually

Jlittle · April 18, 2008, 10:31:23 AM

i mean i dunno, it sounds like the fornt wheel its hard to tell when im going down the road with the sound of the air and all... I can feel it tho and i thought maybe it had something to do with the chain. My uncle(who is a mechanic noticed the chain looked like it was twisted alittle when its sitting on the sprocket. Could that be it?

not 100% on what that means, guess i need a new1? and how does "chain kinking" occur?

The Buddha · April 18, 2008, 11:15:40 AM

Chain, yes, sprokets maybe ... measure and eyeball and test and make sure.
You also have to loosen your chain to where the minimum slack is there at the tightest spot.
Kinking occours when a few pins have gotten bent or otherwise bind up.
Cool.

how's bought a few pictures, up close and 3-4 feet away of the chain and sprockets ?

i'm betting on a beat up chain also.

mmmk, im at work but lemmie go snap one or 2

ok well i dont have a cam beside a cam phone to use and it isnt good enough quality. I figure i might go pick me up a chain today 520 O-ring correct?

Also to get the chain and wheel dead straight I bought a chain alignment tool. Turns out you could just take a metal rod and c-clamp it to your rear sprocket to guide you. It's pretty common to think you could eyeball it straight or use the notch marks but they'll still be up to a couple degrees off. Get it just right and the whole chain just glides quiet and perfect.

With the STOCK sprockets (16T front, 39T rear), you want a 110L (L = LINK) 520 chain. Whether or not you buy O-ring, X-ring, or a roller chain (non O-ring) is a matter for you and your wallet. Remember to buy a good quality chain lube designed for the type of chain you purchase.
