Choosing a bicycle frameset is where a build really starts - and it can also be the most confusing part. You have to weigh frame material, size, condition, and how much you'll spend on the rest of the build. The four framesets here span a wide price range. The lowest price is 77% below the highest, so there is room to match a frameset to your riding style, your size, and your budget.
Quick Take
- Superlight new road option: BXT 700C Carbon Disc Road Frameset - T700/T800 carbon, 950g frame weight.
- Gravel-specific option: BXT Gravel Bike Frameset - carbon frameset with a black matte finish.
- Complete used carbon package: Specialized Roubaix Comp Carbon Frameset - carbon frame, fork, and headset included.
- Low-price road option: Douglas Fusion Aluminum/Carbon Road Frame - aluminum/carbon frame with fork and headset.

Decision Matrix
| Frameset | Consider if | Watch out for |
|---|---|---|
| BXT 700C Carbon Disc Road Frameset | You want a new, light disc-brake road frame and plan a full build around it. | The 52cm frame and Sky Blue finish are specific. |
| BXT Gravel Bike Frameset | You want a gravel-specific frameset with internal routing and disc brakes. | The 54cm frame and BSA bottom bracket need to match your components; no-logo matte is plain. |
| Specialized Roubaix Comp Carbon Frameset | You prefer a used carbon package that includes fork and headset and is ready for a rim-brake build. | It's a 50cm frame with cosmetic wear; rim brakes only. |
| Douglas Fusion Aluminum/Carbon Road Frame | You're on a tighter budget and need a taller road frame with fork and headset included. | The 58cm frame is large, and the finish could use a touch-up. |
Product Notes
BXT 700C Carbon Disc Road Frameset
This frameset puts the focus on weight. BXT builds it from T700 and T800 carbon, and the frame weight is listed at 950g ± 50g for a 56cm frame; the unit here is a 52cm frame in Sky Blue. That makes it an appealing starting point for a light road build. At USD 546.77, it is the highest-priced frame in this group, so it's a choice for riders who want a new frame with a modern disc-brake layout and plan to build the rest of the bike around it. The trade-off is fit and finish: the 52cm size and Sky Blue color are specific, so this frame won't suit every build or every rider.
BXT Gravel Bike Frameset
Gravel riders get a frameset that matches the terrain. BXT uses T1000 carbon for this 700C gravel frame, with internal routing for a clean cable setup and disc-brake mounts. The no-logo black matte finish keeps the frame visually quiet. This listing is a 54cm frame with a BSA threaded bottom bracket. At USD 454.35, it costs $92.42 less than the BXT road frameset in this group, though it's still a substantial part of a build budget. The caveats are the plain matte black look and the need to match your components to the 54cm frame and BSA shell.
Specialized Roubaix Comp Carbon Frameset
Specialized brings a complete front end to the table. This listing includes the Roubaix Comp carbon frame, a matching carbon fork, and an FSA carbon headset, so you don't have to hunt for those parts. At USD 395.00, it sits in the middle of the price range. The frame is 50cm and designed for rim brakes, which makes sense for a classic road build. The used condition is reflected in the description: normal wear, cosmetic scuffs, and some marks. If you're okay with a little patina and prefer rim brakes over disc, this is a convenient way to get a carbon frameset with the fork and headset sorted.
Douglas Fusion Aluminum/Carbon Road Frame
The Douglas Fusion is the price anchor of this group at USD 125.00, and it still includes a carbon fork and headset. The frame itself blends aluminum and carbon, and the 58cm size makes it the largest frameset here. The spacing is 100/130mm, so it pairs with 8- or 9-speed drivetrains. The used condition is part of the story: the finish is worn and could use a deep clean and touch-ups, but the retro graphics and light, stiff ride are a big part of the appeal. If you have a taller build and want to keep the frameset cost down, this is the most direct option.
Final Recommendation by Use Case
- New road build with the superlight carbon frame: choose the BXT 700C Carbon Disc Road Frameset.
- Gravel or all-road build: choose the BXT Gravel Bike Frameset.
- Used road build with fork and headset included: choose the Specialized Roubaix Comp Carbon Frameset.
- Taller rider on a low budget: choose the Douglas Fusion Aluminum/Carbon Road Frame.
