nope I tried a 24 X 1 3/8th" wheel in the back.
The tyre hits the bridges on the frame.

I have cut the bridges off another 20.
I got a 26 X 1.5 tyre on a 7 speed mtb wheel in there
But cant find the frame I did that too.
Maybe i threw it out.

Id cut the head stock for suspension forks on that frame.
so it sat really high.


Also you say that cheap suspension forks arent very good.
but mtbs dont need to have suspension.
