My buddy who has built several bikes and who is very skilled mechanically told me to only use the rubber donut on the inside and not use the donut between the sprocket and spokes. The instructions say dished side in with shiny chrome side in which I followed (but the writing is atrocious and the pictures worse).....this part is opposite Chris Hill's instructions. The two sprockets look very well aligned, though. I managed to get the sprocket nicely center. I am afraid the chain will hit my knobby tire.

make sure you have the dougnut on both sides because what i have heard is you will destroy your spokes. i would definatly sandwhich the spokes with both pads. people that have had the chain hit tires ussually bring out the tensioner a little to get the clearence needed

:confused: I'm a bit cornfused :confused:

I understand that logic, my buddy Ghost0 said to leave the second doughnut off....I think for alignment issues, because this kit says to mount the sprocket opposite of the way Chris Hill shows. I need some solid clarification.

i would wait to see what chris says. i just know what i saw at the bike shop and that was a destroyed wheel with only one doghnut on it. i would think but i could be wrong metal on metal with vibration and contant tugging the metals will be rubbing which cannot be good but as i said i would see what chris or andy or mike has to say since they have both built lots of motorbicycles

USE BOTH RUBBER BUSHINGS! Unless, of course, you don't mind buying new bike parts like me:rolleyes: ) Your spokes will fail. The instructions in my kit reccommed putting the offset sprocket toward the inside. That means the nice chrome finish on mine went on the inside.

THANKS - I think you convinced me with one large hesitation - if I put the rubber spacer (cut tire) in and have the offset sprocket toward the inside , it will be best case spacing for tire clearance - but won't it mess up the engine to rear sprocket alignment? I might be better off turning the sprocket around and having the nice side out for best alignment.

I purchaced my first bike about four years ago assembled. I rode it the first summer and noticed that I had a wowy in my rear wheel. After checking I found a couple of broken spokes. Ridding season was winding down so I continued to ride on it until winter. When snow started flying, I tore the wheel down and found seven broken spokes:eek: and the heads almost worn off of most of the spokes on the drive side. The moral of this story is to never mount metal to metal when it comes to spokes. With spring comming up I would reccomend everyone to go through everything on their bikes and making sure everything is tight and nothing is broke...Kelly

Don't be surprised if your bike actually ends up going slower like mine did when I put the 32t on. MUCH slower with the 28t. :eek: You need to figure in torque and ratio to make a wise descision.

Since the original question seems to have been answered, I have a new one that would fall under the scope of this thread. I bought a 36T sprocket to go on a beach cruiser type bike with coaster brakes. I just put the sprocket on last night and realized that it is very very close to the spokes. I put the chain on to see how much room I would have and its on the scale of millimeters. So my question is this, what do you reccommend I do to remedy this problem? I cant put the other rubber spacer on the outside and "sandwich" the spokes because the way the coaster brake and axel are designed because then my sprocket wouldn't be on the dust cover for my coaster break. I was thinking about getting a large washer, if I can find one, or possible getting some metal and making my own. Suggestions?

It sounds like you left out the rubber spacer from in between the sprocket & spokes??? You need to sandwich the spokes between the two spacers!!! If you have to modify the dust cap or brake arm to make it all work, then do it!
