BMX Problems

I have the same problem, on 2 different bikes
I changed hubs, BBs, sprockets and I run only spline drive sprockets

My lbs can't really tell what's going on
This is indeed really annoying

Have you changed the chain that could be the problem?

Is your hat washer sitting on right? (If you have one, that is)

Yeah its on there correctly

Yep, the chain also...twice, no change

I am going to change the frame and the cranks very soon though )

It's like it has a microscopic wobble from side to side...

Has anyone ever experienced such a massive tight spot?

Maybe your sprocket isn't sitting on the spindle right.
Perhaps your spindle is too small for the sprocket?

My spindle aint as long as the last one but its as thick / wide as the last one also the spacer looks like it fits well as its the one that came with the sprocket

When looking at it; does it look crooked at all?

If you mean the sprocket then no i have had it for a couple of weeks but i havent checked the spindle yet

Ok so I have a few suggestions.
Either A: try to straighten your sprocket, maybe adding a spacer or two if it keeps getting thrown off of alignment.
B: see if there is any sort of warping. Like maybe the sprocket or a couple teeth could be bent.
Or C: check the bolt that tightens the sprocket to the cranks (unless you run a spline drive setup) make sure it's not too loose or tight.

I think i tightend it to much cause i can barely turn it i will try loossing it and see what happens

If i tighten one side is the other suppose to get tighter on its own?

Yeah, you're affectively pulling the axle through to the side you tighten, putting equal force on the other side.

If it's a new sprocket and chain, and both are installed correctly, there must be something else thats continually moving the driver and sprocket closer together/further apart. Bent axles is the only thing I can think of, but even that wouldn't have such a big affect. Other than that, all I can think of is sprocket deflection

I havent got a new chain but have just bought one i only had a new sprocket, apparently your suppose to replace both at the same time?

idk if you're still having this problem.. but i ran into this issue a few months back. what i did was took the washers from my dropout bolts, (back wheel bolts) and switched them to the opposite side and suddenly it worked wonders. hopefully it magically works wonders for you too :/

Moosey, would you have the time to post a pic with the washers?
Because I'm not really sure where they are )

sure thing.

basically, the thin circle thing between the bolt and the dropout.

You could just have a moody chain then. Stretching a chain, or part of the chain is pretty common. Is it tight in the same spot with each rotation?

Nope, the tight spot is in different places on the chain with each rotation

Thx mate!

Tried it, unfortunately it made no difference
Hopefully this will get fixed with a new frame and cranks )

does anyone know what bottom bracket this is? plz help
