Specialized Diverge STR Expert Gravel Bike 2023
Fast, capable and comfortable, Specialized's Diverge STR Expert Gravel Bike extends the remit of the highly successful Diverge range.
Made from FACT 11r carbon, the striking frame has a very clever rear Future Shock built into the top tube that effectively allows the seat tube to move independently of the rest of the frame. This gives up to 30mm of suspension for the rider when seated without any compromise to the bike’s stiffness and efficiency of power transfer. When combined with the front’s 20mm Future Shock headset design, it very effectively isolates the rider from bumps, irregularities in the trail and fatiguing vibrations, giving better control, less tiredness and more traction. Both front and rear systems have hydraulic damping and on-the-fly adjustment whilst the rear shock is also tuneable for rider weight, height and style.
Elsewhere, the frame features Specialized's SWAT internal downtube storage for tools and spares with luggage mounts on the frame and fork for long-distance adventurers. Tyre clearance is good, with space for 700c x 47mm or 650b x 2.1”, giving plenty of potential to build up a very capable and versatile machine for taking on any trail.
The 700c Roval Terra C wheels are designed for off-road use and utilise a 32mm deep carbon rim with a 25mm internal width so that it pairs perfectly with a wide range of tyres. The rims are hooked and tubeless-ready, as are the fast-rolling Tracer Pro 2BR tyres, and are laced around DT Swiss 370 hubs with a ratchet freehub for reliability.
The drivetrain is a curated mix of wireless SRAM Rival eTAP AXS and GX Eagle AXS, giving effortless shifting across the very wide, 11-50t cassette at just a light touch on the lever. The large paddles are simple and intuitive to use; left for easier, right for harder so there is no chance of a miss-shift on rough ground or when wearing gloves.
The build is rounded off with Specialized’s Adventure Gear Hover handlebar with a shallow drop and 12° flare along with an S-Works Carbon seatpost and Body Geometry Power Expert saddle so all the touch points reflect the bike's purpose and prowess.
