2023 Factor Bikes Buyers Guide

We choose to work with Factor because every bike is engineered to deliver exceptional performance and ride quality, using the most advanced technology available. There are no compromises; if it says Factor on the downtube, it’s the very best it can be.

Each Factor model is designed to perform a specific role – some are specialists, others are all-rounders. Of course, there are overlaps between models and we know that many of you enjoy a wide range of riding. That’s why we have assembled this Buyer’s Guide to help you to choose the Factor that’s perfect for you.

To assist you with understanding the character of the bikes, each one is accompanied by several graphics to indicate the terrain and events to which it is best suited, its key qualities, and which other model you might consider. For example, while Factor might refer to the One as a dedicated aero road bike and the O2 VAM as a pure climbing bike, you will still have a blast on the One in the mountains and the O2 VAM is a great road race bike. 

And of course, if you have any further questions after reading, you can contact us by phone, email, or live chat and we will be happy to help out.


Factor call the OSTRO an ‘everything’ bike and we agree. It’s light, smooth and aero, so it’s ready for dream trips to the mountains or to the cobbled Classics, for long weekend rides or fast-paced chaingangs, and it especially loves to be raced.

It can take tyres up to 32mm, so it’s ready for Britain’s rougher tarmac. The pros love it because they never have to sacrifice aerodynamics for lightness or comfort. Everyone else loves the OSTRO because it can do the job of three bikes. Suddenly, N=1.

The Hanzo is Factor’s new aero weapon and it represents a major leap in performance. The Factor engineering team was the first in the industry to capitalise on revised UCI design regulations, leading to the Hanzo’s ultra-narrow frontal area and extended airfoil profiles which cut the air like a blade.

 The wide-stance fork and seatstays work to significantly reduce drag caused by the forward spinning wheels. The elegant mono-riser cockpit delivers gains on all fronts: it’s more aero, stiffer, easier to adjust and also compatible with leading aftermarket extensions, so your perfect position will be easy to achieve. Of course, ride quality hasn’t been forgotten – the Hanzo is stiff, responsive, light and confidence inspiring. Your PBs are doomed.

What’s more, it’s ready to carry what you need without adding drag, thanks to the seat-tube mounted Carbon Stora-Pak for tools, direct-mount toptube bag for nutrition, and between-the-arms bottle mount. The frame is stiff and precise, delivering confident handling that allows you to stay in the extensions more of the time. Of course, the SLiCK also uses all of Factor’s aerodynamics expertise and features the brand’s iconic, unique and wind tunnel proven Twin Vane EVO downtube and Widestance seat stays to guide the airflow, making it searingly quick as well as highly accommodating. It’s like flying first class.
