Product Information

3T Exploro Race GRX 1x Aero Gravel Bike

The all new 3T Exploro Race is engineered to provide you with mud-churning, gravel-spinning and tarmac-smoking speed that has been tried and tested in the real world ... not the wind tunnel. Optimised tube shapes provide aero advantages where most other gravel bikes let you down, even the water bottle holders have been designed with speed in mind, so you can rest assured that this bike is faster than its round tube equivalent when using 40mm tyres and 2 water bottles compared to 28mm slick road tyres and no bottles! 3T have gone the extra step to ensure the frame's geometry provides consistent handling with both a 700c or 650b wheel setup making it easier to switch between each, whilst still benefiting from the technical challenges the trail or road has to throw at you. And if you do fancy hitting the dirt with speed you can run up to 61mm tyres maintaining 90% of the bikes aerodynamic advantages. Finally, Shimano's GRX gravel specific groupset offers smooth 1x11 shifting that won't let you down no matter what surface you're riding on, weather you're riding in or speed you're riding at. 

Full Specification



Designed For

The Exploro is designed to fit road, cross and even mountain bike tyres following the GravelPlus standard. The road and cross tyres are 700c, the mountain bike tyres use the 650b size, ensuring that all of these have virtually the same overall wheel diameter and therefore the same predictable handling. Internal cables, hoses and seatpost clamp clean up the frame aerodynamically and visually. Dedicated FlipTop cable guides are future-proof with in mechanical & electronic versions for single & double chainrings.


Fast & Aero

3T didn’t want the Exploro to be fast in theory, but in the real world. So they tested at a realistic 20mph (32kmh) instead of the standard 30mph (48kmh) and optimized the frame for water bottles (tough to do long, epic rides without). 3T even designed the Sqaero shape to work well when covered in mud! The result? A muddy Exploro with 40mm knobby gravel tyres and 2 water bottles is faster than the equivalent clean round tube bike is with 28mm slick road tires and without bottles. 


The RaceMax

The RaceMax frameset is fastest with 35-42mm WAM tyres. That’s when its top speed rivals the best road bikes out there. 3T call this the RACE set-up. But depending on where you ride and how fast you ride, you may want an even bigger tyre for ultimate traction and control. Good news: 90% of the aerodynamic advantage of the RaceMax frameset still works with tyres up to 61mm WAM. That’s the MAX set-up. Most importantly, 3T engineered this for realistic riding speeds, wind speeds, tyre widths, bottle positions and even for mud. Because 3T don’t care if it is theoretically fast in the windtunnel with a fantasy spec. 3T care if it is fast the way you ride it in real world conditions
