Let me confess, I'm a roadie. Maybe even a single speed hipster if anything. But I saw a sweet Magna Glacier Point 15-speed Shimano-shift drivetrain bike(!!!) for $5 on CL and decided to buy it for fun.
It was really nasty, so I cleaned it up, painted it, tuned it, and went nuts with the rust remover.
I don't have any before pics unfortunately, but here's an after pic with a custom rattlecan paint job and a stenciled thunderbird decal:
Yes, this is my only mountain bike. Today the streets were snowed out so I decided to go to the local woods with my buddy and try it out. Here are some pics:
The seat kinda fell off after a landing a jump near the end, but overall, it was REALLY fun. I may have to join your insanity after all.
