    Default Cast crowns and lugs, is the material strength compromised by overheating/

    When removing and replacing tubes or fork blades from cast crowns or lugs does the structural integrity of the casting suffer from possible overheating? Is the cast material effected the same as tubing if overheated? Is there one particular alloy commonly used in producing these cast components?

    thanks, Brian

    As with anything, it's about your skill level. If you reach a point where you're uncomfortable with the heat, the answer is yes something is affected.

    When using heat to pull pipes out of sockets make sure you know how the pipe was located when first brazed in. Was there a pin?

    I have recycled a couple of crowns over the years but these days don't. The cost for a new crown (and steerer) is far less then that of your reputation or face. Andy
