Factor

Bikeroom's Factor collection focuses on road bikes from this UK-based premium brand. Factor is known for the O2 VAM lightweight climber, the Ostro VAM aero road platform, and the Ostro Gravel. Builds typically feature Shimano Dura-Ace Di2 or SRAM Red eTap AXS, reflecting the brand's performance-first positioning. Pre-owned examples are relatively rare given Factor's lower production volumes compared to mass-market brands — which means the used market tends to be curated rather than flooded.

Factor frames are built to a high standard. Their carbon construction is consistent across the performance range and has proven durable in real-world use. The O2 VAM in particular holds its value and ride character well. When assessing a pre-owned Factor, check the bottom bracket shell — Factor uses proprietary BB86 press-fit on some models, so verify service history and current noise levels. Also confirm that headset integration is undamaged, as Factor uses an internal cable routing system that requires careful handling.
