3T's radical aero gravel bike has been updated for 2018 two years after it first launched

When it launched two years ago the 3T Exploro sent ripples of shock through the internet with its title of the world’s first aerodynamic gravel bike. Two years is an eternity in the bike world and the Italian company has just issued an updated version to ensure it makes use of the latest standards.

There are no fundamental changes to the Exploro frame, but there is a switch from post mount to flat mount disc brakes, and there’s also a new seatpost clamp. It uses a wedge collar design like that found on the newer Strada road bike.

On the subject of the disc brake mount change, 3T’s head designer Gerard Vroomen is clearly not impressed by what he sees as another new standard.

“Postmount brakes work perfectly well, so there was no reason for the industry to invent a second standard (the whole idea of a standard is that there’s only one). But it’s hard to avoid when Shimano decides to push this,” he explains.

The biggest change is not in the frame but actually up front, with an all-new fork. The previous Luteus II fork has been replaced by the Fango fork (Italian for mud) which has a slimmer crown, more aerodynamic fork blades and fully internal hose routing. The dropouts have dedicated 12mm thru-axle threads and the company specs the Syntace X-12 axle, which 3T reckons is the stiffest axle available.

The updated Exploro frameset is available in Team version weighing 1,090g (size medium) in a red paint finish, while the LTD uses a lighter paint finish to bring the frame weight down to 990g. The new fork weighs 400g with an uncut steerer tube.

The original Exploro with post mount remains available and is a good option if you want to use mountain bike brake calipers, which are still all post mount. Only the road industry has gone to flat mount.

We'll confirm the price as soon as we get it.
