Currently building up a couple of old road bikes.
Anyone who moans about new ‘standards’ clearly hasn’t tried this. You’ve more chance of finding the newest Trek-Intense-Cannondale BB6589.3 press fit with threaded bearing shells and expanding wedge lock rings standard BB in your LBS than buying a threaded headset and expecting it to fit onto any particular set of threaded forks and frame.
Less forgetting, more having to take it apart yet again because something doesn’t quite fit.
Torx. Torque is a turning force. Torq make energy products. Torx are the tools to fit the matching star-shaped fasteners. Sorry, riles me that one.
And ironically, rubbish at transferring torque. Good spanners are designed to transfer the torque on the flats, not the corners, torx keys do the opposite. The inside of a socket should actually look a bit like the head of a torx key with 6 semi circles.
I’ve a whole tray full of torx bits with twisted splines that are being reserved for the day I ever need to twist something really hard the other way.
