BIRDY JK11 Gravel

An exclusive collaboration with Joseph Kuosac, the JK11 Gravel tackles any terrain in style, from gravel paths to roads to light off-road trails. Its wide, grippy Schwalbe Billy Bonkers tyres easily navigate uneven terrain, while its 11-speed Shimano Ultegra derailleur grants it additional versatility. Its 48T front chainring also mimics full-sized gravel bikes' gear ratios. At the same time, its aerodynamic JK C38C carbon wheelset and trademark Birdy full front & rear suspension system ensure it doesn't sacrifice performance or speed.
