I was doing an in depth cleaning of my bike tonight and I noticed something odd on the cranks. On the inside of the left crank, the numbers “172” are stamped with “H7” stamped underneath the numbers. On the inside of the right crank, “175” is stamped with “G7” stamped underneath the numbers. These are the orginal cranks from when I purchased the QR in 1998.
Does this mean I have a different length cranks on each side?
it appears that you indeed have different length cranks on your bike–one 172 mm and one 175 mm. how could qr or your bike shop let this one by?! pretty funny, but not for you.
one of my teammates was working at the bike shop on campus and accidentally put the cranks on the wrong side of the bike.
Chances are good that you have your cleats off by >2.5mm (i.e., not at exactly the same point on your shoes), and/or that your feet are different lengths, etc. 2.5mm means very, very little. That said, I’d be annoyed and want to fix it, but at least know it’s not doing you harm.

Screw up? By QR? Yes.
Consequences of screw up? None. You rode it like that for 6 years and didn’t notice.
This demonstrates two things: how adaptable the human body is, and how insignificant crank length is.

No, I think not. I think this demonstrates how insignificant 2.5 mm of crank length is.
I think you should quit your job and travel the world in search of the person with the matching set. A may be a beautiful loving and kind woman who has been dreaming of you. You will know her because she walks with a limp, and doesn’t know why.

I said that.
Now you have solved the mystery of why you walk with a limp.
