The Boost, Extended
The 3T Ultra Boost Rival XPLR AXS 700c Gravel E-Bike is perfect for tough gravel with extended battery range. All electronic parts fit neatly inside without the need for bulkier tubes or visible cables. So you keep all the performance features of the original Ultra frames and add one more: extra power whenever you need it.
3T's goal was to keep the fun and flow of a fast, agile gravel bike, not to build a motorcycle with pedals. That means the system has to be very light, offer a very smooth power build-up & create no drag when turned off. In the end, 3T's customized Mahle X-20 system offers all three.
Features:
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!
60MM DOWNTUBE NECK: Upper downtube necks down to 60mm to pick up the airflow coming off the front tire.
75MM DOWNTUBE BASE: Lower downtube aero profile is 75mm wide to fully shield water bottle.
SIZE-SPECIFIC DOWNTUBE: Reduced depth on smaller sizes to keep frame compliant and keep space for bottles.
MINIMALIST CROWN: With the advent of disc brakes, crowns don't need that bulk of material and can be reshaped for better strength, stiffness and weight. Plus better aerodynamics.
PURE-ROAD FORK LENGTH: With the shorter crown, 3T can make their 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.
INTEGRATED FENDER MOUNTS: Invisible until you need them.
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.
