need help with hardtail rear wheel off set

S

supercafe

Coast to Coast
i am building a t100 triumph bobber.
i am in the mock up stage, i installed the fender and then wheel. the sprockets line up, but the rear wheel is off center by 1/2 to 3/4 to the right. now it is a 16 inch rim.
my question is that can i move the tire over by tightening the spokes???
there is no more room for spacers, the brake plate is a hair away from the frame.
can i run the wheel off center like this. sprokets line up etc. all looks good be sides the wheel.
any thoughts on this. and i know pics would make this easier, but have'nt got any yet.
thanks,
 
There's not much spoke length in a 16" wheel to pull the rim over one side that far. You'd be lucky to tighten one side to move it 3/8". Not always the best idea to have the wheels not run on the same track but with a bobber I doubt you'll experience anything dangerous.
 
Izmir the hardtail straight? If your sprockets are aligned, the wheel should be in the correct position.
 
Is the wheel off center from the backbone, or off center between the frame rails. Got any pics from behind the bike to see where you are off center

Is the wheel/sprocket/brake the original set up or some new combination? If it is the OEM set up as long as the spacers are in the correct location it should line up in the new frame axle brackets. Unless you welded up the hardtail without using a jig, in which case heat has a tendency to move things. Check backbone centerline to see if axle brackets are equal distance on either side.
 
thanks for the replys.
i will get some pics up soon.
on other sites they say this is normal for bobber/hardtails. the wrencher in me says , What the hell are they talking about normal????????????? things should be centered and aligned!
any way, looking down the back bone with no wheel or fender, every thing looks good, same from behind.
install fender, measure the distance to center it. then look down the bone and it is centered.
installed the wheel and checked the sprockets, and they are lines up.
checked the wheel, and it is over to the right of the bone, about 1/2-3/4.
looking at the center line of the tire, then look at the left side tread of the tire, thats what is lines with the back bone.
if you can pitcher that,
i am not sure if it is oem wheel, i belive its a triumph hub.
the chrome brake plate, where the brake stop rod conects to is hairs away from the hardtail.
and the spacer on the right fits right in with little room.
every thing looks like it is all lines up. nothing is bent or out of line. just the wheel looks like it need to move on the hub to the left.

I will get some pics up tonight, and make sense of all this.
may be need a new rim, hub assy????? not sure if its oem or not, ill leave it up to u guys to decide. hard to find good pics of this stuff.
any way, thanks again.
 
Sounds like just the offset on the wheel is wrong. You were on the right track when you said about moving the wheel over by adjusting the spokes. Of course you have to make sure that you do not encounter chain rub (on the tyre) if you offset by the amount you are talking about.
 
so u can use the spokes to move the rim and wheel over the hub and still keep it balanced and true??
i would like to move it over by atleast and most 1/2 inch. that would make me alittle more worm and fuzzy.
thanks for the reply.

Yes, this is called dishing. All multispeed bicycles with a rear wheel gear cluster have dished wheels to accommodate the cogs. All the rear motorcycle wheels I've built also have some amount of dish. The hub flanges are not centered to the frame so one side of the spokes must be tighter to pull it over. This is easier to do with longer spokes so I don't know how much you can do with shorter spokes on a 16" wheel.
 
thanks drj
at least i can try,
i went out on the bike last night and foregot to take some pics, so i will tonight.
any way, thanks.
 
I moved a 17" wheel rim over 10mm one time. If you have the tyre and tube on the wheel you will have to remove them as the spokes will dig in to the tube when you tighten the spokes on the side you are moving over. The will poke into the tube, all you have to do is file or sand the tops off the spokes once you have the wheel set.

problem i see with it is, if you look at the pics, the longer spokes are on the right and the shorter on the left.

thanks.
