Nukeproof Mega Carbon Bearings: Resolve the Two Parts Lists
Nukeproof Mega Carbon bearings require more identification than a generic search for a pivot kit. The 2023 MK4 manual contains an NP-numbered bearing inventory in its specification table and a differently named set in its available-spares table. Those records should remain separate until a supplier confirms which parts match the actual frame and drawing positions. Similar-looking numbers do not resolve the difference.
Nukeproof Mega Carbon bearings: Copy the complete specification inventory
Printed page 36 lists two NP-5 bearings described as 6902 2RS, four NP-7 described as 6800 2RS, and four NP-9 described as 61802-2RS1 EXTENDED. That exact inventory appears in both the 275 and 290 carbon specification tables. Preserve the quantities and the extended description rather than reducing the enquiry to a single familiar bearing number.
The word extended is part of the recorded NP-9 description. It should not disappear because a retailer offers another bearing with a similar basic code. Equally, this table does not supply a complete dimensional drawing or authorise substitution from a different frame. Give the supplier the complete entry and the identified Mega platform rather than treating an abbreviated code as an approved replacement.
Compare the diagram-based spares page without merging it
Page 40 gives F6902 LLU MAX-EA at diagram position 4, BB 6902 LLU MAX at position 9, and BB F6802 LLU MAX at position 15. These are the names printed in that separate bearing-kit section. The exploded drawing is on page 35. Use the drawing positions with the spares table, and retain page 36 as a separate source when asking for clarification.
Do not claim that the NP-5, NP-7 and NP-9 names are proven one-to-one equivalents of those three spares entries. The document does not provide that cross-reference in the cited rows. A kit description, loose bearing and adjacent pivot hardware may also be different purchase items. State exactly which item or complete assembly the workshop needs, with photographs where appropriate.
Have play assessed before deciding what to replace
The maintenance section asks owners to check pivot points for play and refers to the specified bolt torques. It says bearings may need replacement if play remains after the relevant checks, and directs owners to a reputable mechanic or authorised dealer. That is not a diagnosis that every noise comes from a bearing, nor a reason to increase tightening beyond the applicable instructions.
For broader context, see the Nukeproof topic and brand introduction. For a repair, obtain a confirmed parts list tied to the actual frame and assessed fault. This article supplies no bearing-press sequence, removal force or substitute dimensions. Its purpose is to keep the conflicting inventories visible so an order can be answered accurately.
FAQ
Are the NP references the same names as the spares-page codes?
No. The two pages use different descriptions and do not provide a confirmed equivalence table.
Which drawing accompanies the numbered spares entries?
The exploded frame drawing is printed on page 35; the spares list refers to its positions.
Does a creak by itself prove that a pivot bearing needs replacement?
No. The actual fault and assembly require assessment rather than a diagnosis from one sound.

The MK4 manual uses different bearing references in its specification and spares pages. Keep both lists and drawing positions when asking for the correct kit.
