We had an issue with some of the Marin speced wheels the last couple of years. Spoke breakage without a riding history of hard use and in a short period after bike purchase. I don't know if your wheels are the model that we suffered with. While in each case Marin did come through with suitable credit or replacement it was like pulling teeth.

As a big rider you'll have more issues with any wheel you use then small guys. I hope these wheels do you right. Andy.
