Rear wheel/fork allignment

Howdy guys!

I'm new around here, just a real quick question.

'Recently finished my first SS/Fixie build. The only problem i have left is that my rear forks seem to lean towards my Drive Side by about 1-2cm.

This means that my rear wheel is 1-2cm to the right of my bike and out of alignment with the center.

I've read about cold setting and all that jazz, but first off, i want to know what is actually wrong with having the wheel to one side.

Any one good at physics?

What wheel did you put on your bike? A flip-flop track hub wheelset you bought for it?

I am thinking that you put a 120mm spaced hub in a road frame which will be 125mm or 130mm depending on the frame.

This could have happened. There was quite a bit of bending of the rear forks when i install the wheel.
I thought this was fine.
I have done this a couple of times though, and it always goes towards my drive side.

Is there anything stopping me from using spacers to get the rim back into the middle?

IT WILL EXPLODE!!!

Sorry!

If your axel is long enough, just add spacers in the hub. I hope you know where to put them.

Did you look at the link? They talked about the same thing, adding spacers to get a 120mm hub to fit nicely in a 124mm pair of rear dropouts.

If bending as you tightened your wheel in occurred then it most likely is too wide. use a measure and measure it. If you are unsure about the hub, take a photo or take it to the LBS

OP: Start from the beginning.
Exactly how wide are your dropouts and the axle spacing on the wheel? Is it a steel frame? What kind of wheel?

I measured my axle length and dropout width and
Axle = 120
Dropout = 130

Is this the reason my wheel is unaligned?

Can i ride my bike as it is, with the wheel unaligned until i fix this problem?

Should i get a new frame or try cold setting it?

(It's a steel frame)


It's a flip flop track wheel.
