If the bolt spins in the hanger the threads are indeed stripped. The threads on the bolt don't look too badly damaged, so the hanger is where the threads are properly stripped out. The tops of the th …

Derailleur hangers are typically made from a flat plate of alloy, and are not bent to position the derailleur in or outboard. I'm guessing, but if you have the correct hanger I suspect you have it mo …

Addressing what tool to use. Use the box/ring end of a decent quality wrench to get the bolt off. Don't use an adjustable wrench, these are prone to slip on tight bolts and will mar the bolt head flat …

I'll be getting a set of 622 rims laced up so I can use locally available tires. (currently has well worn 27 x 1 3/8 on 630 rims). You'll need to make sure your brake calipers have sufficient rea …

TLDR: You have a standard mount hanger, leave the B pivot on the derailleur. Looking at this Wheels Manufacturing page, what they call 'direct' hangers put the M10 mounting hole further to the rear t …

If your rear spacing measures 115mm it might actually be designed as 110mm or 120mm. See here for standard hub spacings. 120mm freewheel hubs should be available, but you will only be able to fit a …

Derailleur hangers are supposed to be, to some degree, a component that bends to save the derailleur. The hanger on one of my bikes seems to get bent at the slightest impact. I'm considering ordering …
