Riding things that are too big for you happens when you are younger because
"you will grow into it" but also when we are older (but none the wiser!) because they are so damn comfy/upright compared to 90s sized stuff we rode/raced on with them crazy high posts and crazy long stems. I bought a 1988 22" Hardrock (I'm only 170cm) for the Suntour parts to rob off it, but I'm tempted to keep the whole bike because if makes me grin every time I get on it. So I can see why your obsessed with riding BIG things!
