Factor O2 VAM 2025: Test Ride, Review, Pros, Cons, Performance, Range, Opinions – Everything You REALLY Need to Know

 


Factor O2 VAM 2025 Test Review Build Quality

Like all FACTOR bikes, the build quality is high, with a well-made frame and meticulous assembly.

The range of builds is good, as is the size range.

A rational racing bike, perhaps a bit too bland, even in its graphics, but it all depends on performance.

One of the flaws is the limited sales and service network.

Factor O2 VAM 2025 Test Review Frame

The Factor O2 VAM 2025 frame has been further refined, stiffer, and lighter.

The size range is good.

The choice of builds is equally good.

Overall, nothing has been left to chance and everything is well-made.

The weight is excellent, with the top-of-the-line version weighing in at 6.2 kg, rising to 6.7 kg with the Shimano Ultegra Di2 version.

The quality-price ratio isn't great, but it's in line with its competitors.

Factor O2 VAM 2025 test review Assemblies

The range of assemblies is comprehensive.

The only downside is the lack of a wide color selection.

The quality is always excellent, but the prices are high.

Factor O2 VAM 2025 test review Comfort

The ride comfort of the Factor O2 VAM 2025 isn't the best; it's not an uncomfortable racing bike, but it's hardly comfortable.

It's not the most uncomfortable racing bike out there; let's just say it's in line with other racing bikes of similar weight and cost.

The integrated seatpost has a negative impact.

A true racing bike that sacrifices little or nothing in terms of ride comfort.

Factor O2 VAM 2025 test review

A true racing bike, very responsive, easy to handle, and quick to enter corners and change direction.

It's not affected much by crosswinds, but at high speeds it needs to be ridden decisively, otherwise it's imprecise and unstable.

Likewise, decisiveness and a firm grip on the handlebars are required when riding over rough asphalt.

Even downhill, experience and decisiveness are required, as the steering is sensitive to every input.

With a little experience, you can fully exploit this frame's potential, but it's not an easy racing bike to ride at high speeds.

It performs excellently on climbs, but caution is required when braking, as the reactive frame can react nervously to deceleration.

It's a high-performance racing bike, but it also requires experience and commitment to ride.

At a touring pace, it's easy to ride, but not very pleasant because it's uncomfortable.

Factor O2 VAM 2025 test review Performance

The Factor O2 VAM 2025 offers top-notch performance among racing bikes, a very lightweight racing bike, with a sub-par build.

On climbs, it's one of the absolute best bikes you can own.

Lightweight, fast, and outperforming all its competitors.

It also performs well on flats and hills.

It excels on climbs, where it has no real rivals.

It holds its own well on hills, but struggles on long flat sections, where other stiffer and more aerodynamic frames perform better.

On descents, it's incredibly fast, but requires considerable riding skill and a great deal of experience.

Overall, a racing bike with top-notch performance, but not easy to ride.

Factor O2 VAM 2025 Test Review: Strengths and Cons

The Factor O2 VAM 2025 has proven to be a top-of-the-line racing bike, often outperforming its best competitors.

An excellent climbing bike, it also performs well on flats, downhills, and hills.

However, it requires a certain amount of riding experience to achieve top performance, and its integrated seatpost limits ride comfort.

It's not cheap and has a limited sales network.

In the end, it's a more than excellent racing bike, and sometimes the best overall, but it's not a bike for everyone, due to its price and the effort it requires to ride.

In terms of performance, it's at the absolute top of the market.
