Gravel capability, electric assistance, and urban-friendly control are all combined in the 2024 3T Exploro RaceMax Boost GRX Flatbar. The Mahle X35 rear hub motor and internal 250Wh battery provide smooth, natural-feeling support when the route gets rough or the load becomes heavy, while the carbon RaceMax frame is designed for speed over a variety of terrain. When combined with Shimano GRX 1x11 gears and hydraulic disc brakes for dependable performance on pavement, gravel, or mixed routes, the flat handlebar arrangement provides upright comfort and assured steering. It's a quick, stylish e-gravel bike designed for riders seeking efficiency with a competitive edge.
The 2024 3T Exploro RaceMax Boost GRX Flatbar is designed for riders who want speed and support without the drop-bar posture . Its key features focus on blending performance, subtle assistance, and versatility.
Lightweight Carbon Frame: Built with 3T's high-modulus unidirectional pre-preg carbon, the frame is incredibly lightweight and stiff, sharing the same race-proven geometry and tube shapes as the non-electric Exploro for traditional gravel bike feel and agility .
Mahle X35 Hub Motor System: The bike is powered by the discreet and lightweight Mahle ebikemotion X35 rear hub motor (250W, 40Nm torque). This system is known for its smooth, natural power delivery and near-silent operation, providing assistance up to 25 km/h (for the European market) with almost no resistance when pedaling without power .
Integrated 250Wh Battery: The battery is fully concealed within the downtube, maintaining the bike's clean, aerodynamic aesthetic. An optional range-extending battery can be mounted under the downtube while still leaving room for two water bottle cages inside the front triangle .
Shimano GRX 1x11 Drivetrain: Equipped with a gravel-specific Shimano GRX 800 groupset (RX-812 rear derailleur). This 11-speed mechanical setup provides crisp, reliable shifting and is paired with an 11-42T cassette for a wide gear range suitable for varied terrain .
Flat Bar Configuration: The flat handlebar setup provides a more upright and confident riding position, boosting control and visibility on mixed terrain or city-to-trail transitions .
Generous Tire Clearance: The frame and Fango RaceMax fork offer massive tire clearance, accommodating tires up to 54mm (or even 61mm) . This allows riders to run high-volume rubber for maximum grip and comfort on rough tracks .
A proper fit is crucial for gravel riding performance and comfort. Here are the detailed specifications and geometry for the 2024 3T Exploro RaceMax Boost GRX Flatbar in size 56cm.
Rider Height Recommendation: The size 56cm is generally recommended for riders between approximately 5'9" and 6'0" (175cm - 183cm) .
