Top-carbon road bike Author Charisma 77 with carbon fork. Road racing special with UCI certificate. Carbon models have frames from Japanese carbon fibers Torayca, which are used even for F1 cars. With the ability to tune individual parts of the frame with a different fiber orientation, Charisma offers to riders both enough of torsional rigidity and comfort, especially in the form of absorption shocks from the road. Whether on quality asphalt or adoquins ride becomes more pleasurable and the rider can better focus on his performance. The best from classical racing geometry, curved top tube lies horizontally and very smoothly passes into the seat stays. Their minimalist cross-section is what always allows rider to feel less and less shocks due to the absorption. Conversely, tapered head tube with reinforced bottom diameter of 1.5 inches offers perfect rigidity while going thru bends. Thanks to the racing components set Shimano Dura Ace, carbon wheel set Mavic Cosmic Carbon or saddle Fizik Arione R3 you can focus for 100% only on your performance and overcoming your limits!↓↓↓Add to comparewhere to buyother modelsCharisma 77 2020-21 Interested in other model`s year?20142015201620172018201920202021-22technical specificationgeometry and sizesphotogalleryproduct options Technical specificationSize520, 540, 560, 580, 600, 620 mmFrameAUTHOR A carbon monocoqueFront forkAUTHOR A carbon monocoque 1.5" taperedHead partsFSA Orbit C-40 1.5" taperedChain WheelSHIMANO Dura Ace 53-39 teeth 170 / 172.5 / 175 / 177.5 mm cranksBBPartsSHIMANO Dura Ace BB unitFront derailleurSHIMANO Dura AceRear derailleurSHIMANO Dura AceShiftersSHIMANO Dura Ace (22)Free wheelSHIMANO CS-9000 11-25 (11)ChainSHIMANO 9000HubsMAVIC Pro Cosmic Carbon Chrome 23 WTS 16 / 20 holesBrakesSHIMANO Dura AceBrakes leversSHIMANO Dura AceRimsMAVIC Cosmic Carbone SL WTS 23 wheel Set 16 / 20 holesWheel setMAVIC Cosmic Carbone SL WTS 23 16 / 20 holesSpokesMAVICTiresMAVIC Yksion Pro kevlar 700 x 23cHandlebarRITCHEY SL Road Evo Curve carbon 420 / 440 mmTapesAUTHOR microfiber / gelStemRITCHEY WCS 4-AxisSeat postRITCHEY SL 1B carbon (27.2)Seat clampAUTHOR (31.8)SaddleFIZIK Arione R3Speed22Weight6,9 kg / 54cm Geometry and sizes Size 54 56 58 60Min. figure [cm] 160 168 176 186Max. figure [cm] 170 178 188 195S/T c-t [mm] 540 560 578 600S/T c-c [mm] 488 511 540 550T/T h [mm] 550 563 574 585T/T a [mm] 544 560 574 582H/T [mm] 120 135 155 175C/S [mm] 410 410 410 410W/B [mm] 979 993 995 1005S/T ang.

Shock absorption - better ride comfort. Very low weight. These are the basic advantages of carbon as material. Carbon frames made by AUTHOR MONOCOQUE CARBON TECHNOLOGY are precisely "woven" from carbon fibbers. Thanks to the special shaping of each tube and strengthening critical parts creates a connection between the latest technologies in manufacturing carbon frames and requirements for sport-oriented riders. The used material is Japanese carbon TORAYCA, suppliers of carbon e.g. for F1 or for the production of Boeing aircrafts.UCI certificatedUCI trademark that identifies frames and forks "Approved for racing use." The model, which is marked with this sign, may be used without problems for professional racing.Wheel set Photogallery Product options carbon / white / yellow52 = UA#42869501 54 = UA#42869502 56 = UA#42869503 58 = UA#42869504 60 = UA#42869505 62 = UA#42869506
