TXT PRO 2
TXT PRO 2 is
more than a fast bicycle.
The development of TXT PRO 2 began with a single objective. To create the fastest track frame by redefining the way a bicycle interacts with the air. Every aerodynamic possibility within the 80 mm UCI regulation was reimagined. Every tube profile, surface, and structural junction was engineered to reduce drag while maximizing propulsion. The result is a frame that moves with the air, not against it. Its stiffness structure was also completely re-engineered. Optimized carbon construction transfers sprint power with minimal loss, creating a direct connection between rider and machine. A modular system across the handlebar, axle, and seatpost allows one platform to adapt to every track discipline, from sprint to endurance. TXT PRO 2 is more than a track bike. It is a pure speed platform where air, structure, and rider perform as one.
AERODYNAMICS:
SHAPE of AIR
The fork is the first component to meet the air. The A-Diffuser Fork does more than reduce drag. It captures and guides airflow smoothly through the center of the frame, reducing the low-pressure wake behind the fork and front wheel.
Each fork section features the deepest aerodynamic profile permitted under UCI regulations, allowing the structure to function as one continuous aerodynamic channel. The result is a 5.8% reduction in frontal area and a significantly lower CdA under real riding conditions.
This controlled airflow continues through the seat tube, where TXT PRO 2 introduces Engineered Void, a new form developed with both aerodynamic flow and structural load in mind. The opening disperses airflow while relieving internal frame stress, allowing unnecessary material to be removed without compromising structural integrity.
Inspired by aircraft fuselages and jet engine air ducts, its cross-section is precisely engineered to maintain attached airflow at high speeds while preserving natural pressure balance within the structure.
TXT PRO 2 does not simply cut through the air. From the A-Diffuser Fork to Engineered Void, every form is designed to make airflow part of its performance. It is where aerodynamic and structural efficiency exist in harmony, creating the unmistakable signature of TXT PRO 2.
AERODYNAMICS : SHAPED by VELOCITY
TXT PRO 2 was designed as a single, uninterrupted aerodynamic system. Its seat tube and seatpost feature WheelContour Geometry, a profile precisely shaped to follow the contour of the rear wheel.
Clearance between the frame and wheel is minimized within UCI regulations, allowing airflow to remain attached while reducing flow separation and aerodynamic wake at high speeds. The design also helps maintain stable mass balance along the rider’s centerline, supporting confident handling under maximum power.
During the final stage of development, TXT PRO 2 underwent wind tunnel testing using the same disc wheel configuration used in competition. At an extreme speed of 60 km/h, or 16.7 m/s, frontal aerodynamic drag was reduced by more than 21% compared to the previous generation.
The greatest improvement appears under crosswind conditions. At a 15 degree yaw angle, the refined aerodynamic tubing generates a sailing effect, allowing airflow to contribute to forward motion instead of resistance. As a result, the effective aerodynamic drag area, CdA, drops to as low as 0.068, reducing drag by 46.6% compared to the previous model.
This is not styling. It is the result of aerodynamic efficiency, structural stability, and balanced mass distribution combined in one unified form. While others fight the wind, TXT PRO 2 turns it into forward momentum.
STIFFNESS :
THE FOUNDATION of SPEED
Stiffness is not simply about making a frame harder. It is about balancing strength where power is generated with compliance where control is required.
TXT PRO 2 features an asymmetric oversized power transfer core extending from the bottom bracket shell to the chainstays. Built with High Modulus Carbon and WINACT-G3 Nano Carbon Technology, this structure minimizes frame torsion under maximum load.
Refined through extensive sprint simulations and track testing, it delivers exceptional traction and stability under the highest sprint and cornering loads. If aerodynamics determines top speed, stiffness determines how quickly you reach it. Every watt of the rider’s power is converted directly into forward acceleration.
Modular Dropout System
TXT PRO 2 removes the boundary between training and racing. Its Modular End system is integrated into both the front and rear dropouts, allowing seamless compatibility with both Quick Release and Thru-Axle wheel systems on a single frame.
The front fork shares the standard 100 mm road hub spacing, making it easy to use conventional road wheelsets for daily training while reserving dedicated track wheels, including disc wheels, for competition. The rear maintains the 120 mm track standard, preserving the ride feel required for race-day performance.
One frame. Training and racing without compromise. A solution unique to TXT PRO 2.
Engineered for 76T
Modern track racing demands bigger gears and wider tires. TXT PRO 2 expands frame compatibility to give riders complete freedom in setup.The optimized chainstay and bottom bracket design accommodates chainrings up to 76T, exceeding the capacity of many flagship track frames. Every gear combination fits without compromise, converting maximum power into forward speed.
With clearance for tires up to 28C, TXT PRO 2 delivers the ideal balance of rolling efficiency and aerodynamics. Built for race-winning performance and everyday training, all on a single platform.
GEOMETRY
TXT PRO 2 is available in four frame sizes, XS, S, M, and L. Combined with multiple handlebar and stem options, it offers an optimized fit for every rider.
The geometry of TXT PRO 2 is engineered for instant response and high-speed stability. A longer effective top tube than the previous generation enhances cornering stability while maintaining the rider’s center of gravity during explosive sprint efforts.
The newly introduced XS size is designed specifically for elite female athletes and smaller riders. It preserves the intended race geometry while delivering a precise fit, allowing every rider to unlock the full performance of TXT PRO 2.
