Uncompromising Racing Focus
Aero Downforce and Efficiency
D-Type Intake
The T1600’s distinctive D-Type Intake blends a sculpted fairing and aerodynamic tailfin to create a D-shaped airflow path through the seat tube region.
The result is a boost in aerodynamic efficiency and added downforce at high speeds, delivering a planted, confident feel when it matters most.
Razor-Sharp Aerodynamics
Jet-Inspired Head Tube
A fighter jet for the road.
Inspired by the nosecone of a supersonic aircraft, the T1600’s ultra-narrow head tube slices through the wind with minimal frontal drag.
This cutting-edge design reduces resistance and maximizes aerodynamic performance, giving you a clear advantage in breakaways and sprints.
Light & Fast
Featherweight Frame
Lightweight without compromise.
Meticulously engineered using high-modulus carbon fiber and precision layup techniques, the T1600 frame weighs in at just 900g.
Its structure is optimized for stiffness and strength, giving you lightning-fast acceleration without sacrificing durability.
Backed by data. Built for speed
Wind Tunnel Proven
In wind tunnel testing, the T1600 saved an average of 5.5 watts at 48 km/h over 100 km compared to the previous-generation T1550.
This is real-world performance proven by science, and felt every time you turn the pedals.
Greater Stability
Fork-Tail Aero Wing
Sculpted for the wind. Stable in the storm.
Engineered with a unique trailing edge, the Fork-Tail Aero Wing minimizes turbulence around the fork and front wheel.
Additionally, the fully enclosed right-side axle design keeps the dropout surface flush for reduced drag and cleaner integration
The result is smoother airflow, enhanced control, and greater stability in crosswinds.
Seamless and Durable Integration
Proprietary Enclosed Right Axle
The fully enclosed right-side axle design keeps the dropout surface flush for reduced drag and cleaner integration. It is an aerodynamic advantage engineered for durability and a finishing touch that shows no detail is too small in the pursuit of speed.
Stiffness Meets Reliability
T47 Threaded Bottom Bracket
The T1600 uses a T47 threaded bottom bracket to combine the stiffness benefits of oversized bearings with the ease of serviceability of a threaded system.
This interface ensures a solid, creak-free connection between the crankset and frame that can handle the power demands of elite riders.
