High tech aero performance
The timemachine TM02 shares most of the TM01's revolutionary technologies. The SubA concept reduces drag to a minimum by the use of tripwire technology and truncated profiles. The P2P seatpost offers a huge adjustment range that makes sure you find your perfect position. Same as with the TM01, a high level of integration takes components out of the wind and into the frame.

BMC TM02 Ultegra
We loved this bike's smooth ride. "It felt stable cornering, was confident on descents, and was very responsive to accelerations," said one tester. The bike's position should suit most cyclists-it's efficient, but not uncomfortably long and low. The lightest bike of the bunch, it flew over the many hills on our test loop.
The aerodynamics of the rider and the bike are influenced both by the position of the rider on the bike and by the aerodynamics of the bike itself.
subA refers to the maximization of the aerodynamics by minimizing the frontal area of the bike. This is generated by three core features:
Tear drop 3:1 - The frame shape is formed aerodynamically in a length to width ratio of 3:1.
Truncated profile - Instead of continuing the surface in a teardrop shape, a straight break-away edge is worked into the profile. The turbulence can be managed and controlled by this. The minimized raw materials also reduce the weight and increase the stiffness of the frame due to the edge.
Tripwire - Tripwire is the "tripwire for the air", originally an achievement from aeronautics: special wind curbs are molded into the carbon frame so that the slightest turbulence is created directly above the surface. A sort of air cushion forms for the wind flow.
With these cranks, the bearings are pressed directly into the frame. The diameter of the axle is 30 mm. The advantages of a BB30 crankset are greater stiffness with a lower total weight.
