Birdy JK11 Ace (11 Speeds)

The Birdy Jk11 Ace is the latest 11 speed Birdy model with 20-inch Joseph Kuosac carbon wheelset and the top-end DuraAce R9100SS 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.

Equipped with the Ergon SMC Sport Gel saddle and Ergon GP2-L grips for improved comfort, the JK11 Ace does not neglect the control with its DMR V12 Magnesium pedals.
