Choosing between a dedicated gravel bike and a road bike with endurance geometry can be the hardest part of shopping for a drop-bar ride. The four bikes here range from a 54cm Specialized Diverge Elite to a 2022 Giant Revolt Advanced carbon gravel bike, with a 2019 Specialized Diverge Sport and a Specialized Roubaix Sport SL6 in between. The trade-off between carbon compliance and component spec is exactly what makes this group worth comparing.
Quick take
No single bike is best for every surface, so the decision starts with whether you ride more pavement or more dirt. For the lowest listed price, the Specialized Diverge Elite E5 2022 in blue offers a gravel frame with hydraulic disc brakes, drop bars, and less than 500 miles. For a carbon gravel rider, the Giant Revolt Advanced GRX brings a 1x11 Shimano GRX groupset and 700c wheels. If your routes tilt toward pavement, the Specialized Roubaix Sport SL6 is a carbon road bike with Future Shock 1.5 and upgraded Easton EC70 carbon aero bars. The 2019 Diverge Sport is listed as 'for parts or not working,' so treat it as a components donor unless you plan a full rebuild.

Product notes
Specialized Diverge Sport Gravel Bike - 2019, 56cm
At its listed price, this 56cm bike sits between the other two Specialized models in this comparison, but its condition is 'for parts or not working.' That makes it a pick for someone who sees the Shimano Ultegra R8000 hydraulic brakeset, shifters, front and rear derailleurs, DT Swiss R470 wheelset, and Temani carbon seatpost as donor parts for another frame. It includes a drop bar and derailleur gears, so the component roster is complete. The limitation is obvious: don't expect a rideable bike out of the box. If you're not doing the work yourself, the other Specialized options are more practical.
Specialized Diverge Elite E5 2022 54 700C Hyd Disc Drop Bar Gravel Blue
This blue 54cm gravel bike is the most affordable of the group. The condition is 'new other (see details),' and the item has less than 500 miles and upgraded handlebar wrap. Hydraulic disc brakes and a drop bar make it a strong candidate for mixed-surface riding. The frame size is 54cm, so it's aimed at a specific rider height, and the drivetrain uses derailleur gears. The limitation is that the condition is 'new other,' not 'new,' so it's not a factory-sealed product. If the price and size line up, this is the one to start with.
2022 Giant Revolt Advanced GRX Carbon Gravel Bike (Size Medium
For its listed price, this used carbon gravel bike from Giant combines an Advanced-grade composite frame with a Shimano GRX 1x11 groupset. The build includes 700c wheels, Maxxis Rambler 700x40c tires, a D-Fuse carbon seatpost, and a flip chip on the rear dropout to adjust wheelbase and tire clearance. The frame size is medium, and the color is Panther Green Metallic. The limitation is that it's a used bike, though it's fully serviced. If you want a 1x drivetrain and carbon compliance, this is the one to focus on.
Specialized Roubaix Sport SL6 Carbon Road Bike, 52cm, EC70 Carbon Aero Bars
This 52cm carbon road bike is the only entry that is not a gravel bike. It has Specialized endurance geometry and Future Shock 1.5, plus an Easton EC70 carbon flat-top aero bar and Continental Grand Prix TLR tubeless-ready tires. It's used with low miles and professionally inspected and tuned. The limitation is that it's a road bike, so if your definition of gravel includes loose, deep, or chunky surfaces, the other three are more direct fits. For mixed pavement and light dirt, though, its road geometry and shock-absorbing bar make it worth considering.
Final recommendation
Match the bike to the surface and the frame size you need. The Specialized Diverge Elite E5 2022 is the least expensive gravel bike here, and its 'new other' condition and low-mile history make it the simplest choice for a shopper who wants a drop-bar gravel bike without the highest listed price. If carbon is your priority and you want a 1x11 GRX build, the Giant Revolt Advanced is the one to put at the top of your list. The Roubaix Sport SL6 is a road bike with endurance geometry, so choose it only if your gravel routes are more like smooth dirt paths. And the 2019 Diverge Sport is a parts bike because of its 'for parts or not working' condition; skip it unless you're rebuilding.
