Update here and need advice. So here's what was quoted to me on a new build at the beginning of all this stupidness:
Dimension Road Rear Wheel 700c 36h Shimano Tiagra / Mavic Open Sport Silver 1 $128.00 T
Dimension Road Front Wheel 700c Shimano Tiagra / Mavic Open Sport Silver 1 $116.00 T
So it turns out I actually wound up with two 32h wheels - one of which -rear- pancakes/goes out of true under my weight. This was a custom build where I said I wanted strong wheels from the get go.
LBS says they can either take the rear back and build up what they promised at no cost or order me a DT Swiss TK540 36h 700c Black rim for 120.
Which should I do? I'm 240lbs with a 15-20lbs pack. They haven't addressed what they're going to do about the front wheel.
