Frame spreading

[stoppit]

Problem: back of bike, where the rear wheel slides in, is too narrow for the axle.

Solution?: spread the rear forks/whatever and weld in a bar to bridge the gap you create.

Anybody else had to do this? Suggestions?

I saw a topic about it awhile ago.

Search around. Maybe someone here has the link.

Basically, take a 2x4 and find a way to leverage it on the rear stays and the upper tube of the frame, then do it again to the other side, about the same distance

Use a wind up car jack, skwish it beween th chain stays with some pieces of wood to protect the paint, and wind out the jack.

yep many ways work

a long threaded all thread bolt
nuts with washers inside
start turning the nuts out -- pushes frame out pretty easy

if troubles -- tie bolt to frame area -- so as not to let it slip out

Many Ways

A pressure treated 4 x 4 and a ratchet strap.

cool. ideally, i suppose you would need to have a wheel to be test fitting right?

Muscle power, lots of sweat and a heck of a lot of cussing. Make sure your kids aren't around.

actually a very easy job to do

actually a very easy job to do
in the bike shop days
it never took more than a minute or two
but I will admit if doing this to my own bike today
I may take up to five minutes

((not wanting to bend only one side of frame)) -- (((((that's not good)))))

just ((a little bend)) ((on both sides))
