Become a rear derailleur hanger for BROMPTON. It is manufactured by cutting out the 7075AL (super -super -geralmin) block.
Very hard and high strength. It is common whether a rear derailleur hanger can be attached and removed on the road and MTB, but it is common, but
Most things are casting. I think the sharpened rear derailleur hanger is quite rare.. As an aside,
When I was working for a bicycle shop, there were some that the customer fell and the R -derailler hanger was bent or broken.. Because it is a casting, it bends easily, and if the impact is strong, it will easily break.. If it's just bent, bend by hand,
If you give the pulley and cassette croquette parallel, the shifting will be restored.. or,
The bend in the rear derailleur hanger may cause damage to the derailleur itself.
Speaking of this part, it is good if it is hard, it is not good because it is sharpened.. Conversely, if you think that the frame manufacturer can no longer get a rear derailleur hanger as a small part,
If the rear derailleur hanger breaks or cannot be restored, the frame itself may be useless.
I think the hanger is better as it is shaved or hard material.. I used to downhill at the Fujimi Panoram Ski Resort in the past
I was running on a play bike while doing street skills in the city, so
Sometimes I had fallen and broke down bicycles in the air, so
The rear derailleur is doing things that don't break so easily, so
I think that the rear derailleur hanger should be stiffer, so
I use 7075AL.. Please think about various things before bidding.
