Have an issue with a brand new db release 29 I got this week. Drive side crank hits the chainstay under heavy pedaling. Have about 15mm clearance on non drive side, but only 5 or 6mm on drive side. I have a release 2 as well to compare it to - crank clearance is equal on both sides. Crank arm doesn't appear bent and bb is properly installed with single drive side spacer. I used string and tape measure to check frame alignment and seems ok. Q factor seem correct and centered on the frame. Compared to release 2, only thing that seams odd is chainstays dont have as much curve inward toward the wheels on the 29er. Seems to be 6 to 8mm wider from stay to stay than My release 2 right where the end of the cranks pass the chainstay. My understanding is this bike is a catch frame with 29" wheels. Hoping any catch owners could tell me how much space should be between chainstay and crank arm.
At this point, think I may have a bent or deformed rear triangle from the factory.
I have ticket opened with db and waiting to hear back.
