Factor O2 VAM Bottom Bracket: Why T47A and BBright Records Differ
Factor O2 VAM bottom bracket searches can return two incompatible descriptions: T47A on the current model page and BBright in the general FAQ. Both are genuine manufacturer records. The useful response is to identify which frame and document generation each describes, rather than combine their dimensions into one replacement specification.
Factor O2 VAM bottom bracket records on the current page
The model feature names CeramicSpeed T47A and explicitly describes a threaded bottom bracket. Its detailed row lists aluminium cups and CeramicSpeed bearings available for DUB, 24mm or Ultra-Torque. Those source options do not mean every bearing arrangement is installed together, or that an uninspected crank will fit every package.
The 2023 O2 VAM manual also depicts threaded cups. It separately names SRAM DUB 29mm and Shimano Hollowtech II 24mm reducer arrangements. Those are descriptions inside that manual’s assembly context, not instructions here to buy a reducer from its diameter alone.
Why the BBright answer must stay separate
The general FAQ groups O2 VAM among BBright bicycles, giving a 79mm shell width and a 46mm bore for PF30-style cups. It is therefore not safe to attach that answer to the current T47A entry without checking generation. Factor O2 VAM BBright information remains useful for identifying the older record; it does not erase the current threaded description.
The manual index labels O2 Disc as v1.06, and the linked filename also says v1.06. The actual captured cover prints V1.05. That document depicts a bearing press and BBright reducers for 24 or 22mm cranks. Preserve all three labels when asking which instructions apply, rather than quietly standardising them to one version.
Identify the frame before the replacement
A Factor O2 VAM crank interface enquiry should include the actual frame identity and the installed crank details. The catalogue listing is Factor O2 VAM - SRAM Force w/ Power Meter Bike — Chrome.
For Factor O2 VAM T47A or Factor O2 VAM bottom bracket generation questions, send the supplier the conflicting passages and the frame details. Request the applicable complete assembly and instructions. This article does not approve pressing, threading or adapting any particular hardware into the seven listed size options. Use the Factor overview to distinguish the bicycle families, and the brand topic to retain this unresolved generation question.
FAQ
Does the FAQ prove the current model is BBright?
No. Its broad answer conflicts with the current T47A model record and needs generation identification.
Is v1.06 printed on the older manual cover?
No. The index and filename say v1.06; the captured cover says V1.05.
Do matching crank diameters establish a complete compatible assembly?
No. The frame interface, cups, bearings and applicable instructions still need confirmation.
