Specialized’s Diverge has always been at the forefront of gravel, and with every iteration, the brand has tweaked it with fancy technologies in pursuit of comfort and speed. Though upon the release of the Diverge 4, there was something missing – the S-Works build. Now it’s finally here, and it’s every bit as progressive as its whopping £11,999 price tag would suggest.

Spesh says the Diverge has always been about adventure in one form or another, but with the new S-Works build, the brand reckons that it’s turned its escapade intentions up to 11.

That’s said to have been achieved through three points. First up, it uses Specialized’s Future Shock 3.3 that claims to boost integration by welcoming internal cable routing. What makes this a little more interesting than your regular cable-routed headset is that Future Shock 3.3 is a hydraulic damper that promises a smoother and more comfortable ride. Running the cables through it doesn’t exactly mean much in terms of performance gains; rather, it makes the bike look a lot tidier.

However, the benefit of Future Shock 3.3 is that it’s apparently more aerodynamic than a suspension fork, up to 400g lighter, more serviceable, and more tuneable. Additionally, this particular version of Future Shock cannot be fitted onto the other current Diverge 4 models.

Where you might find a performance gain is in the frame. Where all other Diverge 4 models utilise Specialized’s 9r carbon layup, the S-Works Diverge 4 gets a Fact 12r layup. Spesh says that it’s been engineered for responsiveness and efficiency, so I expect that it’ll be a tad stiffer, but the brand also says that this carbon sheds 200g off the frame, compared to the 9r carbon frames. As for complete bike weight, a size 56cm is said to tip the scale at 8.2kg.

Lastly, claiming to be the ‘ultimate expression of gravel adventures’, the S-Works Diverge 4 is loaded with top-shelf kit. That includes Roval’s spendy Terra CLX III wheels, a Roval Terra cockpit and SRAM’s Red XPLR drivetrain. As for the bearings, you bet that there’s a CeramicSpeed headset and bottom bracket.

Elsewhere, the bike boasts space for up to 50mm tyres with 7mm of additional clearance, and it can fit up to 46t one-by chainrings. Specialized even says that the S-Works Diverge 4 can fit large 52t chainrings, but that’s only at the rider’s risk. Two-by setups can also be installed.

If you’ve got a couple of quid stuffed behind the sofa, the Specialized S-Works Diverge 4 will set you back £11,999.
