Ah well... now I know to look out for those things. I very sensibly swerved to avoid the one that was about 100 feet after the first.

In retrospect I'm surprised I managed to bike over it at all... And I'm glad it was on the surly 'cause I woulda cried if I did it on my other bikes, I'd expect they'd not have done as well.

I'm going to call the base provost and find out who to complain to about those 2 grates... Because that is pretty retarded and if that's their fitness circuit they should really make it non-hazardous to cyclists.

the spokes looked fine - the rim's kinda bowed out on either side probably in an area that's less than a finger across.. I'm hoping that if I cut a piece of wood to fit in the rim, and then put a flat piece of wood or aluminum across either side of it, I can put a clamp across it and bend them inwards & flat.

I'm not thrilled at the idea of buying another new rim for it now, but I probably will eventually end up doing that. either way, it sounds like I got off lighter than you did with your seven - I hope you weren't hurt.
