The places where two of the cracks are at the back are where the shell sort of pivots when you put weight on it. Functionally, it seems like not an issue. The thing might even be more comfortable post-cracking. Thanks guys, I'm gonna put it on the craigslist for an OBO price and see what happens.

One dustcap is missing, the other is an MKS. I might rebuild the pedals and snag another MKS dustcap just so they match and all.
