Factor ONE SP – SRAM Force AXS
The Factor ONE SP combines the aerodynamic performance of the ONE with a purpose-built time trial cockpit, creating a bike designed to go fast against the clock while retaining the handling and agility of a road bike. This version pairs the ONE SP platform with SRAM Force AXS and a power meter, creating a race-ready specification with wireless electronic shifting and integrated power measurement. Built around a Black Inc 62 wheelset, it is a complete performance package for riders who want a fast, highly adjustable TT or triathlon bike without the compromises of a traditional time trial platform. *image for illustration only£9,699.00

Faster by Design
Factor developed the ONE SP from the aerodynamic ONE platform rather than starting with a conventional TT design.
That means you get the ONE’s distinctive wide-stance fork, integrated front end, progressive geometry and low-weight carbon construction, combined with the position and aerodynamics required for racing against the clock.
The result is a bike that makes particular sense for riders who regularly encounter climbing, technical sections or changing road conditions alongside high-speed flat sections.
Road-bike handling meets TT aerodynamics.
Purpose-Built ONE SP Bar
The ONE SP Bar is central to the bike’s performance.
Its high-modulus carbon construction provides the stiffness and control required at race speed, while the direct four-bolt connection to the fork head creates a highly integrated front end.
Position adjustment is extensive, with reach, width and rotation adjustment plus up to 35 mm of extension stack adjustment in 5 mm increments. An optional 10 mm of additional stack is also available at the bar attachment.
For long-course triathlon or shorter technical time trials, this gives you the flexibility to find a position that works for your body, your event and your course.
SRAM Force AXS with Power Meter
The SRAM Force AXS groupset gives the ONE SP a clean, wireless electronic drivetrain with straightforward shifting and race-ready performance.
The integrated power meter provides consistent power data for training and racing, making this a particularly strong specification for riders who train and race with power as a key performance metric.
The ONE SP is compatible with both 1x and 2x electronic drivetrain configurations, allowing the final gearing to be tailored to your events and terrain.
Black Inc 62 Wheels
The Force AXS build is paired with Black Inc 62 wheels, creating an aerodynamic wheel and frame combination designed around high-speed racing.
Together with the ONE SP’s integrated front end, internal cable routing and aero-optimised frame profiles, the result is a complete system focused on maintaining speed.
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.
