I finally got around to finishing off the chain replacement on the ST3. All was going well until I went to tighten up the front sprocket nut. I had my trusty torque wrench to hand, which has served me well for many years. Then I checked the required torque for the sprocket nut. How fucking much??? 135 ft-lbs (183 Nm) that's how much. My old torque wrench tops out at 105 ft-lbs so that's no good. Still every cloud and all that - it's an excuse to get a shiny new Halfords professional jobbie that tops out at 225 ft-lbs. That should take care of any and all likely future needs.
