Smaller wheels, bigger tires, rowdier personality. The burly Hook EXT-C is a full carbon frame and forkset - built for the most extreme drop bar adventures. Besides adding a wider, more durable T47 bottom bracket, the cable routing has been revised to keep the bike looking clean with any combination of derailleurs and dropper posts. Besides this, the bike retains the same gorgeous matte metallic paint scheme and awesome parts list that's made it a pin-up for many gravel nerds.
