The Birdy JK11 Ace is MV's latest customised speedster 11-speed Birdy model with 20-inch Joseph Kuosac carbon wheelset and the top-of-the-line Dura-Ace R9100-SS 11-speed derailleur. Its 11-28T cassette is coupled with the Driveline ZELE 54T chainring and benefits from the 4-piston JuinTech GT cable-actuated hydraulic brake system.
Together with a pair of very comfortable Ergon GP2-L handlebar grips and DMR V12 magnesium pedals (weigh 350 grams) that run on fully sealed bearings and a Cro-Mo Axle, the JK11 Ace offers complete control for riders.
