SPRINTER RX

A frame specifically designed for time trials. Its design is based on the requirements for minimum wind resistance. In order to achieve this, it is produced from special aero profiled tubing and includes an aero JET seatpost  (material 7020T6). The tubes are specially designed to be aerodynamic without losing any stiffness, ensuring maximum power transfer. A very short rear triangle is used to eliminate the turbulence that originates in the gap between the seat tube and the rear wheel.

The time trial special Sprinter RX frame is used for racing in the Sports Club of Cyclists Prostějov coached by the chief trainer Mgr. Vladimíř Vačkář. Thanks to its very high firmness and rigidity achieved by usage of aero-profiles in individual tubes, the racer's force exerted on the pedal is transferred with almost one hundred percent efficiency; this frame thus completely satisfies racing demands. We recommend equipping it with carbon components for increased comfort during the ride. It satisfies UCI requirements.

Standard equipment: rear brake cable routed inside the frame, two pairs of braze-ons for bottle cages, a replaceable derailleur hanger, welded front derailleur bracket, Jet seat clamp, cable slide, chain suspender, headset 1–1/8" FSA ORBIT IS, aluminium JET aero seatpost

Additional features: modification for an electronic Shimano Dura-Ace or Shimano Ultegra set

Mating dimensions: headset diameter 45 mm, BSA bottom bracket thread (68 mm)

TT with DI2

Di2 battery is placed on the down tube of model Sprinter RX. The Shimano Di2 battery is a 7.4V, high performance Lithium Ion battery designed to deliver reliable, long life even in the worst conditions. In conditions requiring consistent and frequent shifting, the battery is capable of 1000 kilometers of use. The cables are inside the tubes - inner cables leading!

Shimano Dura-Ace Electronic front derailleur is fully automatic front derailleur powered by a servo motor. Auto trim by itself! Engineering at its finest!

Shifting levels DI2

Electrically actuated shifting significantly eliminates issues associated with cable friction and contamination because the derailleurs respond to electrical impulses that are delivered in fractions of a second. The shifters are now merely switches which also allows for creative placement of optional remote shifters while also reducing the weight and profile of the main shift units. Derailleur movement is precisely controlled through computer automated movement and servo motors creating perfectly synchronized and calibrated shifts every time.
