Wringing extra speed out of your engine isn't always about digging deeper in the pain cave. With the BMC Timemachine TMR01 Ultegra 2015 Road Bike, you simply get farther down the road than the competition with every pedal stroke. With the TMR01, BMC wasn't so much entering the aero road bike category: We were redefining it by creating a road-specific timemachine that combines maximized aerodynamics, integration and stiffness. After extensive wind tunnel testing, the TMR01 earned its wings under the most powerful rouleurs of the professional peloton.
Applied Aerodynamics: The frame of the TMR01 shares technology features with the record-breaking time trial and triathlon bike, the BMC timemachine TM01. The SubA concept summarizes its aerodynamic advantages: truncated tubes strike a balance between the aerodynamically optimal shape and maximum rigidity. The tripwire technology is a stepped profile running along the leading edges of the frame tubing: this provides better control of the air flow around the profiles and delays separation of the boundary layer from the tube surface- the same effect is generated by the dimples on a golf ball.
