I purchased Trek Checkpoint SL5 in April this year and I really like it. The only problem I have is that the crank on the left side is so close to the frame that small gravel is getting between the crank and the frame and scratching the frame. Some of the scratches are pretty deep. I can see the carbon. The bike has only about 200 miles but all gravel. I am not sure what to do. I just don't think the film protector will help in this case.
