75mm Downtube Base
Lower downtube aero profile is 75mm wide to fully shield water bottle.
60mm Downtube Neck
Upper downtube necks down to 60mm to pick up the airflow coming off the front tire.
Mind The Gap
No oversized gaps between front tire & downtube for better airflow transition and less turbulence.
Fork Accessory Mount
Equipe your Extrema for adventure using the three accessory mount rivets on either side of the fork for an anything cage.
Minimalist Crown
Fork crown shapes haven’t changed much since brakes were attached there. Now that we have disc brakes, we don’t need that bulk of material and can reshape the crown for better strength, stiffness and weight. Plus better aerodynamics.
Monster 700c Clearance
Clearance for up to 57mm WAM (29”/700c)!
Perfect Aero Cutout
Close-fitting cutout to shield the rear wheel and achieve the most speed.
