yea i have the same one. you can make a 6.5 fit relatively easily. they are ok but the 8mm chains on them are a joke. also the freewheels and the brake rotor bolts will break at any moment.
Did not come with one. I received it as you see it. It is a freebie.
The scrap guy I deal with saves this stuff for me.
Frame seems strong, but has problems such as seized front shock tubes.
The seized shocks are easy to sort out. I took mine apart a few weeks ago, and they are really easy to put back together again. Mine seemed to have trapped air in them which made it impossible to compress. As soon as I opened them up, the air was released and they work perfectly now.
If it is not air, you will just need to dissasemble the parts and give them a good clean.
