When you're shopping for a road gravel bike, the first question isn't always brand or color. You have to decide whether you're looking for a complete bike you can ride immediately or a component upgrade that makes an existing bike better. This lineup covers both paths.
Quick Take
The group includes two complete Trek Domane endurance bikes, one complete Cannondale Synapse endurance bike, and a SUPERTEAM carbon wheelset. Listed prices span from $339.50 for the wheelset to $3,500 for the Trek Domane SL5. If you want one modern complete package, the Domane SL5 is the most current build. If electronic shifting matters most, the used Trek Domane 5.9 is your match. If you want the lowest-priced complete bike here, the Cannondale Synapse is the one. And if you already own a road bike, the SUPERTEAM wheelset offers a carbon upgrade at the lowest listed price in the group.

Product Notes
#### Trek Domane SL5 Carbon Endurance 56cm Road Bike Disc Brake 2023
This is the only complete bike in the lineup with disc brakes, and the frame includes details that make all-road riding more practical: internal storage, fender mounts, a tapered head tube, internal cable routing, and a 3S chain keeper. The listed build pairs the 500 Series OCLV Carbon frame with Shimano 105 R7020 11-speed shifting, Bontrager Paradigm alloy wheels, and 700x32 tubeless-ready tires. The package comes with both short and tall carbon seatposts, so you can tune the fit and ride height more than with a single-post bike. Choose it if you want the most complete modern road-oriented package here. The trade-off is the highest listed price in the group, a 56cm frame size, and its used condition.
#### Used Trek Domane 5.9, Shimano Ultegra Di2, Carbon Endurance Road Bike-2014, 58cm
If electronic shifting is your priority, this used Trek Domane 5.9 is the only bike here with a Shimano Ultegra Di2 electronic group. The listed build includes Di2 R8050 shifters and derailleurs, an Ultegra R8000 crankset, a Bontrager Race Lite TLR wheelset, and a Zipp Service Course finishing kit. The 58cm frame is sized for riders around 5 ft 10 in to 6 ft 2 in, according to the description, and the complete bike is listed at 16 lbs 8 oz. It's a lighter, more race-oriented feel than the newer Domane SL5, but it uses traditional caliper brakes rather than discs. The limitation is the 2014 model year, rim brakes, and a 58cm frame that won't fit smaller riders.
#### Cannondale Synapse Carbon Endurance Road Bike - Size 51cm
This Cannondale Synapse is the lowest-priced complete bike in the group. It's a 51cm full-carbon endurance frame with Cannondale's SAVE micro-suspension design meant to smooth long road rides. The listed drivetrain is a mixed Shimano 10-speed setup with a Shimano rear derailleur, Shimano Sora front derailleur, and FSA Gossamer compact 50/34 crankset, plus rim caliper brakes and 700x25c road tires. The description suggests a rider fit of roughly 5 ft 5 in to 5 ft 8 in, making this the best match in the group for shorter riders. Choose it if you want a carbon endurance bike with that price position and you're comfortable with a used, mixed-group build. The trade-offs are rim brakes and the more limited 51cm size.
#### SUPERTEAM Disc Brake Wheels 700C Carbon Wheelset 50mm Disc Brake Road Bike Wheel
This SUPERTEAM product isn't a bike; it's a 700C carbon wheelset listed as new, with 50mm depth, 28mm outer width, 21mm inner width, and tubeless compatibility. It's built for road bikes with disc brakes and supports both center lock and 6-bolt disc rotor mounts, with hand-built 2X cross lacing on the drive side and radial non-drive lacing. The hub spacing includes 12x100mm and 9x100mm front, 12x142mm and 10x135mm rear, with Shimano 8-12s and SRAM XDR 12s freehub compatibility. Choose it if you already own a road disc brake bike and want to upgrade to a 50mm carbon wheelset without buying a new complete bicycle. The limitation is that it's only a wheelset, so you need a matching frame, disc brakes, and freehub standard. Its listed weight is 1504g±50g.
Final Recommendation by Use Case
- For a complete, modern road bike: The Trek Domane SL5 is the strongest match because it combines carbon endurance geometry, Shimano 105, internal storage, fender mounts, and two seatposts in one package.
- For electronic shifting: The Used Trek Domane 5.9 Di2 gives you Ultegra Di2 at a lower listed price than the SL5, but you'll accept rim brakes and a 2014 build.
- For a low-priced complete carbon bike: The Cannondale Synapse is the most accessible complete bike here, provided the fit works for you.
- For an upgrade to an existing disc-brake bike: The SUPERTEAM wheelset is the lowest-priced product in this group and swaps in a 50mm carbon disc-brake wheelset when your frame and hub spacing match.
