That's right, I haven't changed the tire or the chamber, but the socket wrench works fine. I used it and the 27mm version to loosen the rear axle bolt to adjust the chain. It was not difficult to untie a properly dressed mother. I tried tightening the axle with just wrenches and the torque wrench clicked after I applied a little more torque to allow you to tighten the axle bolt just enough. The 22mm and 27mm box wrenches for my levers come in handy for prying the shifters out after a fall. I've already fixed the shifters for a couple of friends that fell off. :-)
