Having shifting issues? Watch this video to identify some the most likely culprits.

Dialing in your shifting involves proper hi and low set screw positioning, appropriate B tension positioning as well as proper cable tension.

Incorrect limit settings create chains that shift into the frame or wheel. This can be destructive to both spokes, chains and rear triangles.

Cable tension issues result in poor shift response either up or down the cassette. Too much tension will keep a derailleur from the small, fastest gears. Too little tension and the chain won’t climb into the larger gears.

B-tension setup is important to overall shifting, particularly with the new 12sp Eagle systems. For precise setup use the b-tension spacer included with the Eagle derailleur.

If the set screws are adjusted appropriately and you cannot get crisp shifting it’s time to look for something loose or bent.

Common things to check: loose axle, cassette or rear derailleur mount.

Bent rear derailleur or hanger (a very minor bend will create shifting issues)


In the weeds? Work with a quality resource to ensure proper performance. i.e. – dropping chains into carbon frames or your wheel may cause damage.
