The first gravel bike with 20mm of suspension, we review just how fast this offroad rocket, the Specialized Diverge Comp, has the potential to be.

Hitting the gravel at speed, and not feeling the bumps
Overall Score
Proper offroad geometry and 20mm of suspension to take the sting out the trail
You might need more aggressive tyres for proper offroad

We would classify the Diverge Comp as a 'Performance Adventure' machine - with its 38mm tyres it is capable of tackling some pretty tough terrain, yet it retains the long legs of a road bike with a 48 tooth big ring. The frame is Specialized's FACT9 carbon, as is the straight bladed fork, which keeps things light and rigid. It also sports some innovative features such as the 20mm travel suspension at the head tube, enough to take the buzz out of lumpy fire roads and trails while helping retain control when it gets rough, and front and rear thru-axles.

Specialized have lengthened the wheelbase of the Diverge Comp and lowered the bottom bracket height over a more traditional cross bike geometry, both moves designed to make the bike more stable over rough ground at speed. Combined with 20mm travel at the front end this really is a gravel bike that should eat up the offroad sections quicker than most.

Even the tyres are built for speed, with the supplied Specialized Trigger Pros coming with a fast rolling centre tread for speedy road progress while chunky side knobs bite into softer ground when required.

The massively capable Shimano 105 drives the whole show with an 2x11 drivetrain, while Shimano RS505 hydraulic brakes bring it all to a stop just as reliably.

This rough, tough and ruthlessly efficient frame and spec should make offroad adventures fast and fun.
