For the construction we utilized advanced aerospace composite optimization software to revolutionize the construction & layup of our new FACT 10r carbon. Its the most advanced layup schedule weve ever madethe shape schedule & material optimization allowed us to shed nearly 20% of the frame weightthe perfect recipe for your next hill climb pr. We started by further improving our rider-first engineered technology to ensure that the new Tarmac is stiff & compliant in exactly the right places all while shedding some serious weight. With this revamp we also updated the geometrybasing it on countless retl data points & professional rider input. This enabled us to develop a performance road geometry that perfects the combination of a responsive front-end & short wheelbase delivering instantaneous response & optimal power transfer. & while stiffness aids in the aforementioned compliance must also be utilized for an optimal ride quality. Thats why we designed a seatpost that builds compliance into the upper 120mm where clamping doesnt happen dropped the seatstays & altered the seat tube shape. We also added tyre clearance up to 30mm which translates to a 28mm turbo cotton on a Roval SLX 24 rim. This allows lower pressures for decreased rolling resistance increased traction & more comfort. Altogether these additions still have the Tarmac riding like a true race-machine but they just take a bit of the sting out of those road imperfections. Youll thank us on your next long ride. & while this is all great we know that aerodynamics are the most important thing we can do to make you faster. Both our bora-hansgrohe & quick-step floors Pro tour riders after all are demanding aero improvements on every bike. With this the aero goal was to discover where we could essentially "add aero for free" by not taking anything away from the hallmarks of the Tarmac design. During the six-month iterative process three areas were discovered where we could do thisa new fork shape dropped seatstays with aero tubes & a d-shaped seatpost & seat tube. The result? A bike thats Approx. 45 seconds faster over 40km compared to other lightweight bikes in the same category. This Tarmac comes ready to race out of the box featuring a crisp Shimano Ultegra 8000 mechanical groupset resplendent DT r 460 wheels & smooth-as-silk 26mm turbo Pro tyres. Featuring our rider-first engineered design that ensures every frame size has the same legendary climbing responsiveness & descending prowess youd expect from a tarmac. The FACT 10r frame is the perfect blend of value & performance. Dt r 460 wheels feature reliable, sealed cartridge hubs, & 20 front & 24 rear spokes that keeps weight low & durability high. The 11-speed Shimano Ultegra 8000 shifting is extremely reliable, lightweight, & precise.
