14 inch bike bottom brackets: FEIMIN, FP-B910 and a sealed cartridge
14 inch bike bottom brackets can be recorded at very different levels of detail. The mint Kross LIFTIE row says FEIMIN; blue says FP-B910 POLYAMIDE. The GB woom GO 2 drivetrain list says sealed cartridge. These are useful starting identifiers, but none is a complete replacement specification simply because it appears beside a fourteen-inch bicycle.
Read the actual 14 inch bike bottom brackets entries
On the Kross pages, both labels sit under the bottom-bracket heading. Preserve FEIMIN as the mint entry and FP-B910 POLYAMIDE as the blue entry. They should not be shortened into one generic LIFTIE component when enquiring about a particular build.
The word POLYAMIDE is part of the blue source designation. The inspected row does not explain which part of the assembly that wording describes. It therefore does not establish that every bearing or the entire bottom bracket is made from that material.
Woom's sealed-cartridge statement gives a different kind of description. It appears in GO 2's drivetrain section alongside the crank and pedal entries, without a shell width, thread standard or spindle measurement. Its absence of a named model should not be filled with the Kross identifier.
GO 2's three bearing locations need three separate records
The GO 2 wheel specification describes aluminium hubs with sealed bearings. Its headset specification separately describes a fully integrated one-inch headset with sealed industrial-grade bearings. The drivetrain's sealed cartridge is a third entry in a different location.
| GO 2 location | Published wording |
|---|---|
| Wheels | Hubs with sealed bearings |
| Steering assembly | Integrated one-inch headset; sealed bearings |
| Drivetrain | Sealed cartridge |
The one-inch headset label belongs to the steering assembly. Moving it into a bottom-bracket enquiry would turn a genuine number into an unsupported drivetrain size. Likewise, a wheel-bearing description does not identify a replacement cartridge for the crank assembly.
Make a parts enquiry about the right assembly
The Kross LIFTIE 14 Mint Matte listing identifies configuration OS (7") 14". For that offer, quote the mint FEIMIN entry and ask for the applicable complete component identification. The blue archive and GO 2 remain comparison records, not interchangeable alternatives authorised by this article.
Describe which location the enquiry concerns and retain any existing part identification with the bicycle's details. A supplier can then clarify the missing specification or applicable inspection. This record does not diagnose noise, set a service interval or provide a removal procedure.
Keeping these 14 inch bike bottom brackets entries separate produces a more useful request than asking for any bearing of the right wheel size. For the wider catalogue, see the 14-inch topic and the woom introduction.
FAQ
Does FP-B910 POLYAMIDE explain every material in the assembly?
No. The inspected designation does not provide that complete material description.
Is GO 2's one-inch figure a bottom-bracket dimension?
No. It appears in the separate headset specification.
Does sealed cartridge approve a shared replacement part?
No. The applicable model and interface specifications still need confirmation.
