Factor ONE SP Premium Package Carbon Triathlon Bike Frameset

The Factor ONE SP Premium Package is a carbon triathlon and time trial frameset built on Factor's ONE aero road platform. It's paired with the purpose-built ONE SP Bar to put the rider in a dedicated aero position. The package includes the frame, ONE Wide Stance Fork, seatpost and ONE SP aerobars. The groupset, wheels and saddle are not included, so it suits riders building a race bike around components they choose themselves.

Most tri and TT bikes use a dedicated time trial frame. The ONE SP instead takes the ONE's wide-stance fork and integrated front end, which Factor developed to manage airflow coming off the front wheel across yaw angles, and adds a TT cockpit that bolts directly to the fork head. Factor designed it to cover short, technical and uphill time trials as well as long-distance triathlon. The goal is a fast, compact position without giving up the ONE's road-bike handling and low weight.

Who It's For

• Triathletes and time trialists building a custom race bike with their own electronic groupset, wheels and saddle

• Riders facing hilly or technical courses who want road-style handling in an aero position

• Long-course athletes who will fine-tune stack with a professional fitter

• Consider a different bike if you run mechanical shifting, want a complete bike, or need standard drop bars for mass-start road racing

What to Look For

• Fit before frame size. Sizes run 47 to 58 cm, and cockpit stack adjusts in small steps. A fit session should decide your size and extension setup before you order.

• Component compatibility. The frame is electronic-only. It uses a T47A bottom bracket for DUB or 24mm spindles, a 54-tooth maximum chainring and 160mm rotors front and rear.

• Tire strategy. Clearance is 34mm measured, so you can choose tire width based on the course rather than the frame.

Key Features

Frame and fork: The frame is built from TeXtreme®, Toray® and Nippon Graphite® pitch-based carbon fiber. The ONE Wide Stance Fork and chin fairing are what set the front end apart. It's designed to handle turbulent air off the front wheel instead of just presenting a narrow profile. Chainstays are 405mm across all sizes, and the head tube angle is 73.3° on the size 54.

ONE SP Bar: The bar is high-modulus carbon for rigidity and precise handling at race speed, attached through a four-bolt interface at the fork head. You can add an optional 10mm of stack at the bar attachment, and the extensions add up to 35mm more in 5mm increments. That range gives fitters room to dial in position without swapping parts. A Black Inc computer mount supports Garmin and Wahoo units.

Drivetrain compatibility: An adjustable front derailleur mount accepts a wide range of gearing, which helps when choosing chainrings for flat or hilly courses. Factor's Mini-UDH low-profile hanger keeps the frame compatible with future derailleurs while minimizing aerodynamic bulk. The bottom bracket runs CeramicSpeed T47A aluminum cups and bearings.

Braking and axles: Hydraulic disc brakes with 160mm rotors, on 12 x 100mm front and 12 x 142mm rear thru-axles. Cable routing is fully internal through the cockpit and frame.

Seatpost and saddle: The seatpost comes in 0mm and 30mm setback versions and the clamps take both 7x7 and 7x9 rails. That covers most saddles triathletes use.

Rider Intent Summary

• Biggest strengths: A front end tuned for aerodynamics, a wide range of cockpit stack adjustment and road-bike handling for varied courses

• Tradeoffs: Sold as a frameset only, electronic groupsets only, and 160mm rotors and 54T chainrings are the maximums

• What makes it different: It's a TT/tri setup built on an aero road platform, with the bar mounted directly to a wide-stance fork, rather than a dedicated TT frame

Victory's Take

Victory believes the ONE SP makes the most sense for the athlete who races both courses that reward handling and long courses that reward staying comfortable in the aero position. At Victory Bicycle Studio, we'd set the cockpit stack in a fit session before building anything else on the frame.
