* Rider heights are approximations. For more accuracy, compare stack/reach with your current bike or visit your 3T retailer. *Please note the choice between a Flatbar or Dropbar bike may affect your fit. For more accuracy, compare stack/reach with your current bike.
** Ultra FORK length is equal to a standard road bike, so this HEADTUBE length can be compared to road bikes. To compare to gravel bikes with standard gravel forks, deduct 25mm from these “road” headtube lengths for a proper comparison.
design in details
75MM DOWNTUBE BASE:
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.
SIZE-SPECIFIC DOWNTUBE:
Reduced depth on smaller sizes to keep frame compliant and keep space for bottles.
PERFECT AERO CUTOUT:
Close-fitting cutout to shield the rear wheel and achieve the most speed.
MIND THE GAP:
No oversized gaps between front tire & downtube for better airflow transition and less turbulence.
HUGE CLEARANCE:
The original Exploro set today’s standard for up to 54mm tire clearance. The Ultra has up to 61mm!
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.
PURE-ROAD FORK LENGTH:
With the shorter crown, we can make our forks 25mm (1 inch) shorter than other gravel bikes. Exactly the same as a road fork. This offers better stiffness, lower weight, an easier steering geometry and better aerodynamics.
DOUBLE-DROP CHAINSTAYS:
Dropping the drive-side chainstay improves tire & crank clearance. Dropping the other side as well creates a much more efficient structure behind the BB for higher stiffness & strength as well as lower weight.
DIRECT-MOUNT REAR BRAKE:
Standard frames require an adaptor to use a 160mm brake rotor. We have integrated that into the frame, meaning you don’t need any extra pieces to attach the brake.
DIRECT-MOUNT FRONT BRAKE:
Standard forks require a flip-flop adaptor to set the correct brake rotor size. Our direct-mount pre-sets the caliper for 160mm rotors without any extra pieces.
SELF-ALIGNING WEDGE CLAMP:
Self-adjusting bolt angle for higher clamping forces with lower torque.
AERO SEATTUBE+ROUND SEATPOST:
The seattube is kept aero yet it fits a round 27.2mm seatpost so you have many round, dropper or suspension post options.
