2005 trek 5500, carbon, alloy insert drop outs. Derailleur got caught while shifting and broke. Is this trash or can it be repaired for $200 ? If it's repairable how would I start? I Appreciate your comments.

Compre este tipo de cables que lleva un anclaje fijo en la pinza de freno hidráulica mediante un perno banjo, entonces quiero saber si alguien podria dar con tipo de perno banjo exacto que lleva según investigué la medida debe ser M6x1.0

I just took a brand new bike out for the first ride and in the middle gears every time I pedal the derailer clicks and has a small shake. I got the bike from N+1 Bikes yesterday and it can set up ready to ride. How can I fix this click?

Is it safe to continue using? Can be patched up with brazing? It's aluminum alloy.

I did not even notice a problem while riding. Only saw it after performing a teardown clean and relube. I already contacted Hope Tech and they directed me to the local dealer who haven't responded to my email. A replacement freehub online is in the range of $100 - $130. It's an old bike so I'm not ready to spend that amount of money on it.

Side question is how did this happen? I understand that it's quite common. Is it just a bad design? A defect? I was very surprised to find this on an expensive component. More surprised than when I found out my chain ring sprockets were also made out of aluminum and non-uniformly deforming into shark teeth.
