Bent inbred – can it be fixed?
This morning my chain locked up whilst I was standing on the pedals, causing the wheel to be pulled out of the dropouts on my 456 (which I have singlespeeded)
Now the wheel touches the drive side chainstay. Turning the wheel the other way round it still touches the drive side chainstay.
I have looked and it seems that the whole rear triangle is now out of alignment (and checked with a second wheel).
Can this be fixed (if so how) or do I need to get a new frame?Posted 8 years ago
Sounds like you need an lbs with one of thesePosted 8 years agotoys19Member
Have you tried it with a different wheel? Maybe the wheel spindle is bent..
Yup I've heard bob jacksons is good, should be able to do it, if not any car place with laser chassis alignment might well have a good go. With inbreds being pretty cheap and all, I could see you spending nearly as much as a new frame, I'd be tempted to get a big scaffold bar and have a go myself..Posted 8 years ago
It is definately the frame not the wheel.
The drop outs are square to one another, its just the whole lot is shifted. So i am not sure that Park Tool kit will work (it seems to say it really is for drop out misalignment.
Its not worth spending a lot of money as they aren't expensivePosted 8 years agoHarry TuttleSubscriber
Check the frame with a bit of string before bending anything. Run the string through the dropouts and round the head tube, then measure from the string to the seat tube, if it's not the same on both side's the frame's bent. Simply bend (with a hub in the dropouts) until it's symmetrical.

i would have a bash at it myself.
a personal challenge/development (like learning to bleed brakes, and service forks, and next on the list, shocks)
probably the best frame to try it on, steel should be ok cold setting, and if you balls it up, is only 135quid for a new one (though not in baby blue i suppose?)
wheel in the dropouts, block of wood under the dropouts, and under the BB/seattube, and then stand on it….. gently 😀Posted 8 years ago
I'll have a go at most things, but I still don't think it is going to be possible to get it to line up correctly.
Standing on it isn't going to work, as I will need to prevent the main triangle from moving.
Perhaps if I was to clamp the bottom bracket housing in my vice I could just bend the triangle back?Posted 8 years agoStonerSubscriber
The wheel isn't perfect, but the wheel from my other bike that is perfect sits the same.
That sheldon page is great, I can now see how it is possible now and if I leave a hub in there.
Although I am a bit nervous about bending against the seat tube. I'll probably put a bit of rag on the tube and then some angle iron to spread the load.Posted 8 years ago
Fixed it 😀
Used Sheldons method to gradually bend it back square, took a fair few goes to get it spot on either side of the seat tube and with a 135mm spacing (the spacing without a wheel fitted before was 142mm due to the damage)
Now can anyone recommend me a guide to truing my wheel as that is a bit out of shapePosted 8 years ago
