Putting back rear wheel (?????)
okay I removed my rear wheel to take something out of my rim that was inside..I have deep V's...(little piece of metal maybe that sneaked in there when buikding...it was a really thin broken spacer)...anyway I put the tire together again and want to know if there is a special way to put back rear wheel...before my chain was pretty tight on there...now I put the wheel back and the chain isn't as tight as the first time...should I just keep yanking back till it is and then tighten the bolts...or what?
|
gotta be more specific, cheif... track drops, horizontal drops, vertical drops?
keep pullin' till it's snug... no tricks or anything. (as long as you have room in the drops, then tighten down as needed. |
horizontal
|
one trick: pull it snug, then tighter one nut enough to hold it in place. pull the other nut back a bit, and snug that one. keep walking it back one at a time until you have both proper chain tension, and proper alignment.
|
Don't just "pull it till it's snug". Sprockets are never perfectly round, so spin the crank and look for the tightest section of chain. At this point, the chain should be able to move up and down about 1/2 inch halfway between the crank and the hub. This is at the TIGHTEST POINT!! To make the whole thing much easier, get a Surly Tuggnut or other chain tensioning device. With the Tuggnut you can remove your wheel and then put it back without changing your chain tension.

Pull the wheel back until tightish then tighten the non-drive side first. I apply a little pressure to the rim to tighten the drive side. Then tighten the drive side. Then I loosen the non-drive side and recenter. If I'm not clear I apologize.

Chain tugs. Problem solved.

flip bike over, lodge one hand in between back tire and the seat tube. you can get your chain really tight this way so make sure it isn't too tight. spin the cranks slowly and check the tension at different spots to make sure it isn't too tight.

would you guys be able to tell if it's tight enough through pictures..I squishing pretty tight..Click to enlarge pictures

plus what noise if any should the bike have??? should it be just silent??
|
You can get it too tight. It will make noise and feel like it's binding. That's bad. You should have about 1/2 inch of play in the chain.
|
For those of you who use Tuggnutts, do you use 2 Tuggnutt's? One on each side?
Has anyone used this version? It comes in pairs...and it is NJS :D http://cgi.ebay.com/NEW-MKS-TRACK-BI...QQcmdZViewItem |
I don't use tugnuts
|
it shouldnt make any noise, if it does it is either too tight or too loose.
|
well I was reading other posts and it said that if the cog and chain are new (the noise is coming from the cog side) then maybe they just need to break in...any thoughts?
|
It's not making "Arrrrg" noises is it? because that seems to be going around ;)
|
seriously now...come on
|
if all the parts are new and stuff it will be a little noise until it breaks in. it could be off a mm or something and that would make some noise too. its a bike, bound to be something making a little buzz or whirrr or clickclick.
|
i've noticed that if it is too tight you can tell by ear. turn it over like you have it in those photos and spin a pedal with your hand. increase speed slightly and listen close, you can sort of feel it tighten at a spot each turn and you'll hear a slightly different noise like its not as free and moving as it should be. you want some slack up and down but none side to side. not too tight not too loose. ride it and feel.
|
that's just your bike saying "i love you" nah, my conversion has always made a little noise when backpedalling, my chainline isn't perfect, within a mil and a half though, so pretty close. It could be that I'm running 1/8 cog, 3/32 ring w/ the 1/8 chain.
|
It'll make noise when you're up close to it adjusting it. No bike is "silent" when off the road and on a workstand or while you're listening intently.
Silence is when you're on the street and you can't hear your drivetrain nor can anyone hear you sneak up on them. |

My best adice is go spend some time at you LBS and ask questions. It is also good to ride with people who know some things or been riding longer then you - They can show you how things should and shouldn't work. A tight chain is a good chain. Get the chain as tight as you can. I stick my lock or water bottle between the rear wheel and the frame to push the wheel back against the chain - this creates a tension and makes sure there is no slack. Trackstands, skids, backward circles and all that stuff is much easier with a tight chain.

the BEST way to tell if your chain is too tight is to turn your bike upside down (or put it in a stand if you have one), spin the cranks a bit, and watch them slow down. Your cranks should slow down VERY gradually and glide smoothly to a stop. If they stop suddenly, your chain is too tight. Sometimes it will even rock back and forth a little at the end, which is even better. This is true of all bearings in your bicycle. Your chain/bearings/etc should be as tight as possible and still allow this sort of test.
