Thanks, Nagrom. You'll have to forgive my ignorance, I honestly wouldn't know how much force that is. I guess my question really is, doing this to carbon framed bikes is within the acceptable limits of the carbon frame? Is there a large margin of error for the strength of the strike, or even the angle of the strike relatively to the axis of the bottom bracket, that the chance of harming the carbon frame is negligible? I can imagine a bike mechanic near the end of the work day being too tired to be so focused mentally.

Edit: Nagrom, no need to answer the above questions. Campag4life's post #126 at http://www.bikeforums.net/showthread...1#post15217471 answered my questions very well. Thanks very much for indulging my questions, Campag4life. I've learned a lot from your educational posts.
