Factor ONE SP – SRAM Red AXS
The Factor ONE SP takes the aerodynamic performance of the ONE and transforms it into a dedicated time trial and triathlon machine. For the rider who wants the highest specification available, this build combines the ONE SP platform with SRAM Red AXS and a power meter, alongside Black Inc 62 wheels. The result is a complete race bike built around aerodynamics, low weight, precise handling and an exceptionally adjustable riding position. Configure your build now:£13,099.00

The ONE SP is Factor’s Speed Package for the ONE.
Rather than developing a conventional TT frame, Factor took the aerodynamic architecture of the ONE and developed a dedicated front end around it.
The result combines the forward, compact position of a modern TT bike with the handling characteristics of a road bike.
That makes the ONE SP particularly well suited to riders who want outright speed but still need a bike that can deal with climbing, technical descents and demanding real-world courses.
The ONE SP Bar
The high-modulus carbon ONE SP Bar attaches directly to the fork head through a four-bolt interface, creating a clean and rigid connection between rider and bike.
It offers a wide range of adjustment for reach, width and rotation, together with up to 35 mm of extension stack adjustment in 5 mm increments.
A further 10 mm of stack can be added at the bar attachment.
This level of adjustability allows the cockpit to be configured around the rider rather than forcing the rider into a predetermined position.
Internal cable routing maintains the clean aerodynamic profile, while a BTA accessory holder and Black Inc computer mount are included.
SRAM Red AXS with Power Meter
At the centre of this build is SRAM Red AXS, SRAM’s top-tier road electronic groupset.
Wireless electronic shifting keeps the cockpit clean and provides fast, precise gear changes, while the integrated power meter gives you the data needed to train and race with accuracy.
The ONE SP’s electronic drivetrain compatibility also allows the gearing to be configured around your racing calendar, whether you’re targeting short time trials, hilly courses or long-distance triathlon.
Black Inc 62
The SRAM Red AXS build is paired with Black Inc 62 wheels to create a highly aerodynamic complete package.
The wheelset complements the ONE SP frame and front end, keeping the focus on sustained speed while retaining the control required for real-world racing.
Designed Around the Complete System
The ONE SP isn’t simply a road bike with clip-on extensions.
The frame, fork and cockpit were developed as a complete aerodynamic system, with the front end designed to manage airflow around the front wheel and rider position.
The ONE SP retains the ONE’s progressive geometry and road-bike characteristics, while creating the forward, compact position required for racing against the clock.
- ONE aerodynamic frame platform
- Purpose-developed ONE SP Bar
- High-modulus carbon cockpit
- Extensive reach, width and rotation adjustment
- Up to 35 mm extension stack adjustment
- Optional 10 mm bar stack
- Fully internal cable routing
- Bayonet fork and chin fairing
- Up to 34 mm measured tyre clearance
- Electronic 1x and 2x drivetrain compatible
- T47A threaded bottom bracket
- Adjustable front derailleur mount
- Factor Mini-UDH
A fast TT bike is only as effective as the position you can hold.
That’s why we recommend getting your sizing and cockpit setup right before the bike is built. At Vires Velo, we can help determine your frame size, cockpit configuration and seatpost position, or complete an idmatch bike fit to establish the correct setup.
Every ONE SP we build is assembled by our experienced workshop team in Norfolk.
Built by Vires Velo
Every ONE SP ordered through Vires Velo can be built to your exact specification by our workshop team in Norfolk.
We can help you choose the right size, cockpit configuration, gearing and component combination for your riding, then build and prepare the bike ready for delivery or collection.
If you’re unsure about your position or sizing, we can also complete an idmatch bike fit before the bike is built and use the resulting data to determine your final setup.
- Complete bikes will be shipped using our Secure Personalised Delivery Service (Some location restrictions apply) where the bike will be delivered to your door, completely built and ready to ride.
- If this service is not available in your area, it will be shipped securely by next-day delivery in a large box, with very little reassembly needed.
