Keep your derailleur in line.

The very first aluminum frames didn't have replaceable dropouts. So, you could bend them back a few times, but then the hanger would snap off and it would be off to the bike shop for a new frame. Thankfully, those days are over. Your Niner frame comes with a replaceable dropout that can be removed if it's bent and replaced with a Niner Replacement Derailleur Hanger.

The Replacement Hanger bolts directly to the frame–it's easy. just make sure you choose the right one. One fits the EMD, Air 9, and Jet 9. Another fits the WFO v.2 12x142mm TA and RIP 9. A third option fits the Air 9 Carbon and Jet 9 RDO. The Other fits the Sir 9 and MCR.

Niner Replacement Derailleur Hangers are made of aluminum and come in black.

Is this the correct hanger for the 2015 Niner Jet 9 Carbon?

Unanswered Question

Photo is the same for all selections, and there is no One 9 RDO listed in the select options. I'm looking for this one...

Unanswered Question

My question is i got a Merlin XLM 29 Titanium bike frame, but the rear derailleur do not have the threading for the rear derailleur to be fixed. So the other option is to get a rear derailleur claw adaptor. Please let me know which is the right claw to purchase. You immediate reply will be of great help.
Please send me a picture of the model or where i can place my order for this item and the cost.

Fixed my shifting issues

  • Familiarity: I've used it once or twice and have initial impressions

Bent my hanger in a crash, swapped out the hanger, and now I'm back to smooth shifting!

Easy part to replace and may be just what you need to fix your derailleur woes.

Now I just need to stop crashing....
