I purchased a new DA 7900 130 172.5 Crankset off eBay but I use Q Rings and didn't realize how stupid it was going to look. I've had the crank for a week and used it on the trainer 4 times with the Qring on it so the rings are new. I'll either sell it for $370 plus shipping or trade it for an FSA K-Force light or maybe SL-K of the same size. Note it doesn't include the BB. I bought it without one and used the one I bought last summer.
