I was riding the bike I recently restored and on it's first long out of town trip, I noticed that the front wheel is twisted off to one side by about 1.2* and the rear wheel is dead straight in the frame.

The handle bars are dead square with the front wheel.

But the bike is pointing slightly sidewards - and the wheels are out of parallel.

The bike is running slightly sidewards.....

So I am thinking that the frame OR the forks, or the frame AND the forks are twisted - out of alignment.

Me thinks that someone has crashed the bike diagonally into a unforgiving object hard enough to twist the front end, or fallen on the frame when it was laying on the ground....

Two easy and basic ways to check it are by line of sight - with the front head stem tube and forks and front wheel (both separately and in combination) being in alignment with the seat post tube.

And or by measuring the diagonals between symetrical points with a big steel rule like to check the forks, one can measure from a centre point - like the brake mount hole at the top of the fork, to the top of the axle hole in each leg.

Etc.

Since the twist is fairly small, I figure that I can twist it back and or buy new forks....
