Your back wheel just ate your derailleur, but don't there's no reason to go cry in the corner. After all, that's why the hanger was made to be replaceable in the first place. With the Ibis Mojo SL RHD Direct Mount derailleur hanger, you're able to bolt up a fresh Shimano derailleur and get back to hammering singletrack. Like the name implies, it's compatible with Mojo SL R, Mojo HD, and HD R frames with a 12x142mm rear axle. The Direct Mount designation indicates that it's built specifically for Shimano's direct mount standard. Or, in other words, simply remove the B knuckle adapter from your late model Shimano derailleur, and it'll bolt right up. Please note that this hanger is only compatible with late model Shimano derailleurs.
