One of my bikes (Evil Giant) has been through so many accidents and misfortunes. Hit by a car, slammed into a tree with me on it, ridden into a swamp, dropped down the side of the mountain, wiped out and slid down a steep gravel road, and ridden by my friend who is trying to lose close to 165 lbs.
But it still is perfectly functional and still rides solid. Never an adjustment needed. Shifts nice and clean. No wheel out of true. No dents or gouges. Just scratches. Maybe its the steel frame. I dunno. I cracked a steel frame before so maybe that's not it. I think it just wants me to crash more.
What do you own that will outlive you?
