2010 DMR Exalt steel cranks 175mm

Do you have issues with even the beefiest modern crankset, because you are big and burly? Do you like dropping huge? Friend of mine bought the same model to drop off garage blocks, and they survived! So I bought one pair too, thinking I was burly and dropping big. But I did not, these are like new and a pair of regular xt are more than able to withstand my street riding. That is why I'm selling them, with their spider for double rings. No bottom bracket, but they fit regular Octalink II bbs.
