RockShox Issues Stop-Ride Warning for Certain 2027 ZEB Forks

Last Updated on October 31, 2026 by Kristina

October 31, 2026 | Safety Alert

Important: RockShox is telling riders to stop using certain 2027-model ZEB suspension forks immediately while the company investigates a possible defect that could cause sudden air-pressure loss. The warning applies to specific fork models and serial numbers—not every mountain bike or every RockShox fork.

If you own a recent mountain bike or electric mountain bike equipped with a ZEB fork, check the fork’s serial number before riding again. A fork can fall within the affected range even if it has not shown any symptoms.

Which RockShox ZEB Forks Are Affected?

According to a statement RockShox provided to Pinkbike on October 30, the company is investigating the following 2027-model-year front suspension forks:

Affected fork model	Serial-number range
ZEB Ultimate	07T6XXXXXXXX–42T6XXXXXXXX
ZEB Ultimate Flight Attendant	07T6XXXXXXXX–42T6XXXXXXXX
ZEB Select+	07T6XXXXXXXX–42T6XXXXXXXX
ZEB Select	07T6XXXXXXXX–42T6XXXXXXXX

The Xs represent the remaining characters in the serial number; they are not characters to look for literally. The specified range covers forks produced during weeks 7 through 42 of 2026. Use both the model and serial number to check whether this warning applies.

How to Check Your RockShox ZEB Serial Number

1. Do not ride the bike while checking. Park it somewhere stable with good lighting.
2. Look at the back of the fork crown—the upper part of the fork assembly where the two upper tubes meet the steerer. The serial number should be visible with the fork installed.
3. Compare the number with the affected range: 07T6XXXXXXXX through 42T6XXXXXXXX.
4. Take a clear photo of the number and write down the exact fork model.
5. If your ZEB is in the listed range, stop riding and contact the shop or bicycle manufacturer that sold you the fork or bike for instructions. If you cannot confidently identify the number, ask a RockShox dealer to verify it before you ride.

RockShox explains how its manufacture-date codes work in its official serial-number guide. You can also use the SRAM product-service portal for product identification and support.

What Is the Safety Concern?

The retailer bulletin reported by Pinkbike identifies an upper fork tube that may be outside manufacturing specifications. During an impact followed by rapid fork extension, a retaining ring in the air-spring assembly could become dislodged. If that happens, the fork could suddenly lose air pressure.

A sudden change in front suspension support can affect handling and control, especially when descending or riding rough terrain. That is why this is a stop-ride warning, not a routine maintenance advisory. Do not try to make an affected fork safe by adding air, adjusting rebound, or continuing to ride cautiously. RockShox has not identified those steps as remedies.

Does the Warning Apply to Electric Mountain Bikes?

Yes, if an e-MTB is fitted with one of the affected ZEB forks. The warning concerns the suspension component, so it can apply to either a traditional mountain bike or an electric mountain bike. The brand name printed on the bicycle frame does not determine whether the fork is included; the specific ZEB model and serial number do.

For general upkeep on unaffected equipment, see our 10 pre-ride checks for e-MTB riders and our guide to troubleshooting an e-bike suspension fork that won’t compress. These guides are not substitutes for the RockShox stop-ride instruction.

What Should Affected Owners Do Next?

• Stop riding the bike until RockShox confirms the appropriate next steps for your specific fork.
• Contact the original retailer, bicycle manufacturer, or an authorized SRAM/RockShox dealer. Provide your fork model, full serial number, and purchase information if available.
• Do not disassemble or attempt to repair the air spring yourself. Suspension parts are pressurized and require appropriate tools and procedures.
• Watch for RockShox updates. The company says it is evaluating the issue and will communicate next steps.

In the statement provided to Pinkbike, RockShox said that if corrective action is required, it intends to work with affected riders to resolve the issue at no cost. A final repair procedure or timeline had not been publicly confirmed as of October 31.

Owners can refer to RockShox service and rider support or SRAM’s safety and recall page for subsequent announcements.

Is This an Official Recall?

As of October 31, 2026, the verified action is a manufacturer stop-ride notice while an investigation is underway. We did not find a finalized corrective action or a ZEB-specific entry on SRAM’s public recall page at the time of this report. A stop-ride notice should be taken seriously whether or not a formal recall has been issued.

The takeaway: If you have a 2027 RockShox ZEB Ultimate, Ultimate Flight Attendant, Select+, or Select fork with a serial number in the specified range, do not ride it. Check with RockShox or your dealer for the next steps rather than waiting for the fork to develop an obvious problem.

Why You Can Trust This Report

This safety report is based on RockShox’s statement published by Pinkbike, the retailer-bulletin details reported on October 30, and RockShox/SRAM’s own service and serial-number resources. We have kept the stop-ride notice separate from a formal recall and have not assumed that a repair, replacement, or resumption-of-riding date has been finalized.
