Factor has introduced the ONE SP, a time trial and triathlon version of the ONE built around a new dedicated cockpit.
Rather than developing a separate frame, Factor kept the existing ONE chassis and added the ONE SP Bar. The bar lets you have a TT bike while retaining the road platform’s geometry, weight, and handling characteristics.
The ONE Platform Gets a TT Front End
The ONE SP came out of the development work behind the standard ONE. Factor says the original frame’s wide-stance fork, head tube, and front-end layout showed enough aerodynamic potential that engineers started testing it for time-trial use.
The answer was a dedicated cockpit, not another frame.
The new ONE SP Bar bolts directly to the fork head through a four-bolt interface and uses a high-modulus carbon construction. Factor claims the system also offers plenty of adjustment. Cables remain fully internal, with compatibility for electronic groupsets and hydraulic disc brakes.
The bar can gain 10cm of stack at the mount, while the extensions offer up to 35mm of additional stack adjustment in 5mm steps. You can also adjust reach, width, and extension rotation.
Designed for Hilly and Technical Time Trials
How does it ride? The ONE SP has already been raced. Factor used the bike during the 2026 Tour de France Femmes avec Zwift time trial, which included a 2km climb averaging 6.9%.
It was also raced at the IRONMAN 70.3 World Championship in Nice, where the course included roughly 1,200 meters of climbing along with technical descending. Those are the kinds of races where the ONE SP makes the most sense.
A dedicated TT frame still has obvious advantages on a flat, straightforward course. The ONE SP is aimed more at events where low weight, cornering, climbing, and braking matter as much as aerodynamics. Plus, keeping the ONE chassis also means the bike should feel more familiar to road riders than a long, low-slung TT frame.
Same Wide Fork and Aero Layout
The frame carries over the regular ONE’s distinctive front end. The wide-stance bayonet fork is designed to control airflow around the front wheel, while the chin fairing helps manage air through the head tube area.
Up to 34mm Tires
The ONE SP keeps clearance for tires measuring up to 34mm. That gives riders some room to tune rolling resistance and comfort depending on the course, particularly for rougher time trials and long-course triathlon. The frame also keeps the adjustable front derailleur mount, allowing for a wide range of gearing options.
Groupset compatibility includes electronic SRAM, Shimano, and Campagnolo.
