I`m not sure if I should try this folder, or the Mechanics folder?
I have a 86' Schwinn Passage.
Whenever I have to take the front tire off, it just pops on and off, no problems.

But when I have to remove the rear tire, I have to give it a good pull to get it off.
And putting it back on is almost impossible! It`s like the opening on the tire is bigger than the opening on the bikes frame!
I almost have try to pull and the frame and try to get the wheel in the slot at the same time. Which you can`t do unless you have four hands.
It`s like the seat stays and chain stays need to be pulled apart?
