I have question about the boom on my new (used) Catrike Road. I have been on it several times since it appeared on my doorstep. When I ride, however, the boom seems to twist as I ride. It always seems to turn toward the right side. This evening it moved enough so that I had trouble shifting the chain on the front chainrings. I was able to stop, loosed the QR bolts, adjust the crank, and then retighten them. It seems to me that the QR bolts are tight...but obviously not tight enough. Is it possible to over-tighten them? I would hate to break them or damage the boom.
