Install Troubleshooting

Having trouble installing one of our cassettes? Here are a few key things to look out for during the install process which could be resulting in difficulties installing the cassette per the install directions. Most commonly, inability to get the steel portion on far enough to engage with the alloy portion.

Symptom: Steel section cannot be installed far enough onto driver to adequately reach alloy section and permit locking interfaces to engage.

Possible Problem: Cassette being installed on XDr driver without the spacer:

Solution: Verify XD or XDr Driver:  The XDr Driver will require a 1.8mm spacer under the cassette. If an undersized spacer is used, it will cause fitment issues.

Symptom: Steel section cannot be installed far enough onto driver to adequately reach alloy section and permit locking interfaces to engage.

Possible Problem: Bushing not fully seated on end of the XD driver: Excess grease or out-of-spec XD Drivers can prevent the bushing from fully seating on the XD driver. When this happens it will make it difficult or impossible to install the steel section far enough onto the driver for the interlocking tabs to engage.

Solution: Thoroughly remove grease from the bushing. After alloy portion of cassette is installed, install the bushing on the driver and verify it is fully seated. Once verified, install the steel portion of the cassette. It will be normal for the lower part of the bushing not to touch the alloy portion of the cassette when fully seated but there should be no gap visible on the inside of the bushing and end of the XD driver.

Symptom: Steel section cannot be installed far enough onto driver to adequately reach alloy section and permit locking interfaces to engage.

Possible Problem: XD Driver Bearing Migration:

Solution: Many XD drivers have a partially exposed bearing on the end of them. This is normal, but in some cases there can be migration of the driver body inward relative to the bearing. This means the bearing is effectively protruding out of the end of the driver body more than it should be and needs to be pressed back in place. This can impact the fit of the bushing and prevent the steel section from being pressed on far enough to engage the interlocking tabs. The correct specification for the bearing to be exposed is 3.5mm. If it is exposed more than that, it should be pressed back into the driver.

Symptom: 3mm set screw holes won't line up or difficulties installing the screw. 

Possible Problem: Burrs preventing full engagement or early production Helix cassette with screw hole in different location.

Solution:

• XCX, TRS and Helix
  • Verify that there are no burrs on the alloy portion of the cassette preventing full locking engagement. Inspect this location on each of the fins from the backside of the alloy section:
    • 
  • Install cassette with out the 3mm set screw. Install wheel on bike and pedal bike around with the chain in the lower portion of the cassette. Make sure to give it a few good hard pedals. Verify hole alignment and install screw.
• Helix: If above points have been attempted and you are still having issues, please reach out to us via the support page of our website.

Removal Troubleshooting

Symptom: Steel section won't break free and seems stuck on the alloy section

Possible Problem: 3mm set screw still in place which holds steel and alloy portions together.

Solution: Remove set screw and repeat removal steps.

Symptom: Steel section won't break free and seems stuck on the alloy section

Possible Problem: Both chainwhips or chainwhip and cassette lockring tool are being placed on steel section of cassette. 

Solution: Ensure 1 chain whip is on the alloy portion of the cassette.
