The XDS X-LAB GT8 is a $3,199 carbon gravel bike that almost every reviewer agrees is an exceptional value on paper, bundling a Shimano GRX Di2 groupset, carbon wheels, carbon cockpit, and a power meter at roughly half the price of comparable Western-brand builds. Consensus on the ride is more mixed: most describe it as a comfortable, stable, mid-range performer with a racy front end and endurance rear, while one tester found it soft, slow, and uninspiring, and several note the claimed 55mm tire clearance is optimistic and the power meter reads high.
Pros
- Outstanding value at $3,199: full carbon frame, carbon wheels, carbon bar/stem/seatpost, electronic GRX Di2 shifting, and a power meter included — roughly half the price of comparable major-brand builds123
- Comfortable, stable ride that absorbs rough roads well, with a racy front end and a more forgiving endurance rear triangle45
- Versatile design: 55mm claimed clearance, in-frame downtube storage, top tube, downtube and triple fork mounts, UDH, and 1x or 2x compatibility216
- High-quality finish and build with all bolts threading cleanly and no assembly issues found in testing12
- Handles and descends confidently, fast on downhills and capable on technical rocky climbs47
- Sold through a US dealer network, so bikes are professionally built and backed by dealer service and warranty (2-year parts, lifetime frame)613
- Sensible, serviceable details: threaded T47 BB, round 27.2mm seatpost (dropper-compatible), external seatpost clamp, separate bar and stem, and optional external cable routing126
- Correctly proportioned cockpit for frame size (39cm bar on medium) and geometry that puts forearms parallel to the ground in an aero position6
Cons
- Claimed 55mm tire clearance is not real — a 55mm tire rubs the frame, so effective clearance is closer to 50mm rear7
- Power meter reads 8–10W high versus a dual-sided reference and needs an app plus personal information to update67
- Ride feel is soft and uninspiring: one tester found it slow with poor power transfer, finishing 11–16 seconds behind a Specialized Diverge in a timed test at equal power7
- Clutchless Shimano GRX Di2 rear derailleur causes severe chain slap and pedal feedback on rough ground7
- Carbon handlebar shape and overly stiff carbon stem criticized; proprietary headset spacers force use of the stock stem71
- Internal storage door is flimsy and cannot securely hold a water bottle; some bikes ship missing bottle cage bolts7
- Stock saddle (Fizik Argo) is hard and uncomfortable, and the zero-offset seatpost made fit difficult for some riders524
- Conservative, run-of-the-mill endurance gravel geometry that feels perched on top in loose fast corners and is not ideal for steep rocky descents6
Key Facts
- Price is $3,199 USD (plus a $199 assembly/delivery fee in one case), sold through US dealers rather than direct-to-consumer216

Reviews & Ratings
09:32The reviewer presents the XDS X-LAB GT8 as a frameset used for a custom gravel race build, noting its full carbon frame, geometry similar to top gravel bikes, and ability to accommodate wide tires. The build includes high-end components like Envy bar/stem, SRAM Red groupset, and Envy G Series wheels, resulting in a 17lb bike priced around $8,000, which the reviewer considers a great value compared to other brands.
12:52The reviewer presents a first look at the XDS X-LAB GT8, a full-carbon gravel bike that debuted in the U.S. around the 2026 Sea Otter Classic. He highlights its exceptional value at $3,199, featuring a Shimano GRX 1x Di2 drivetrain, carbon wheels, power meter, and full carbon cockpit. The bike is in high demand and difficult to restock. The reviewer notes its performance-oriented geometry, versatility with many mounting points, and unique features like a storage compartment and Apple Find My integration in the cranks. He mentions minor fit issues with the zero-offset seatpost and stem length, but overall considers it an incredible find that should make the cycling industry take notice.
15:57The reviewer, JT from Black Next Garage, shares his experience with the XDS X-LAB GT8 (referred to as X-Lab GTA in the transcript), a highly sought-after bike he purchased for a 3,300-mile Underground Railroad ride. He describes it as a hype bike that was sold out everywhere, and he unboxes, assembles, and test rides it. He praises its smooth ride, quickness, and value, but notes some issues like a hard seat, tire limitations for road use, and frame contact while coasting. He concludes it's an excellent upgrade for intermediate riders seeking performance without a high price tag.
01:00:50The reviewer analyzes the XDS X-LAB GT8 gravel bike, arguing that while it offers a carbon frame, Shimano Ultegra Di2, and carbon wheels for $3,200, it is not the industry-destroying bargain the media claims. They criticize several design flaws, including a flexible internal storage door that cannot securely hold a bottle, false tire clearance claims, a stiff carbon handlebar and stem, and a clutchless Shimano groupset that causes severe chain slap. After riding, they find the bike comfortable but extremely slow and uninspiring, concluding it is a mediocre product that could be improved but is hard to recommend over better options from Trek, Specialized, or Giant.
17:22The reviewer compares the XDS X-LAB GT8 to a Specialized Diverge in a time trial after upgrading the GT8 with high-end components. The GT8 is described as having incredibly good handling with slower steering, a larger trail (70mm vs 65mm), a higher bottom bracket (by 5mm), and a longer rear triangle (by 5mm). Despite the upgrades, the GT8 was slower than the Diverge by 11 seconds on the outbound segment and 16 seconds on the return. The reviewer attributes the difference primarily to frame softness affecting power transfer, not aerodynamics. The GT8 is noted as a functional, affordable carbon bike but not a race bike, and the reviewer would not buy it.
23:00The reviewer provides a final review of the XDS X-LAB GT8, a gravel bike he has ridden for over 700 miles. He describes it as a sporty, race-oriented gravel bike with a front end similar to a road racing bike, but with a comfortable rear triangle that gives it endurance characteristics. He details his personal upgrades, discusses the bike's geometry and fit, and notes that it may not suit older riders due to its aggressive position, but he offers a solution using Redshift handlebars. He considers it an excellent value at $3199 and a true 'Gran Turismo' of gravel bikes.
19:07The reviewer tests the XDS X-LAB GT8 gravel bike, praising its value proposition, frame comfort, and versatility, while noting minor issues like seat stay contact and deep-section wheel sensitivity to wind. He considers it an all-rounder that sits between race and endurance gravel bikes.
08:32The reviewer presents the XDS X-LAB GT8 Gravel Bike as an exceptionally competitive and exciting carbon fiber gravel bike, highlighting its comprehensive high-end features at a surprisingly low price point of $3,200. He emphasizes its value, comparing it favorably to Western brands costing $6,000-$7,000.
10:05The reviewer describes the XDS X-LAB GT8 as a Chinese brand gravel bike designed for the American market, sold through US dealers. He notes it has run-of-the-mill endurance gravel geometry but is comfortable, confidence-inspiring, and reactive. The bike offers impressive specs for its price, including electronic shifting, carbon components, and a power meter, though the geometry is not groundbreaking and the power meter reads slightly high.
51:07The reviewer, Josh Ross, discusses the XDS X-Lab GT8 gravel bike as a mid-range bike that offers exceptional value at $3,200, roughly half the price of comparable bikes from major brands. He notes it comes with carbon wheels, electronic shifting, a power meter, and is sold through bike shops rather than direct-to-consumer. While the ride is described as entirely reasonable and fun, it is not particularly exciting or innovative, with handling that is normal and descends like other gravel bikes. The bike is seen as a strong option for consumers seeking a well-rounded, affordable gravel bike, but it may not satisfy those wanting unique features or high-end performance.

The reviewer states the XDS X-Lab GT8 is a gravel bike designed for the US market that offers exceptional value, with a high-end component specification at a competitive price of $3,199. The bike is described as a utilitarian, middle-of-the-road performer with a stable, predictable ride quality, though it leans more toward racing than rough adventure terrain.
15:04The reviewer presents the XDS X-LAB GT8 Gravel Bike as an outrageously good value carbon gravel bike with high-end components at a competitive price point. They describe it as leaning toward the racy end of the gravel spectrum while offering versatility through features like massive tire clearance and frame storage. The reviewer praises the bike's build quality, component spec, and overall performance, though they note some minor drawbacks and express concerns about the company's readiness for Western market demand.
The XDS X-LAB GT8 Gravel Bike is priced at $3199 USD, offering good value for a gravel bike with a 1x GRX groupset and 55mm tyre clearance. However, it has 435mm chainstays which some may find long, and the brand recognition may require explanation to others.
