<\/p>\n

If you missed the news, <\/a>Chinese carbon creators XDS (the same folks behind the XDS-Astana Team) just launched a nine-model entry into the USA market. The line is packed with brand-specific bits, carbon fiber everything, and some enticing pricing. The X-LAB GT8 is the brand\u2019s dedicated carbon gravel bike.<\/p>\n

But unlike most brands’ market entry, it’s not a race-only bike. For XDS\/X-LAB there are no claims of \u201clightest\/fastest bike ever\u201d<\/em> (though the X-LAB AD9 might be the lightest); it’s \u201cjust\u201d <\/em>a solid, modern gravel bike priced to move.<\/p>\n

What Is It? X-LAB GT8 Gravel Bike<\/h2>\n

The GT8 has all the trappings of a modern race bike: internal cable routing, integrated cock pit, UDH, internal storage, and massive tire clearance. The frame is crafted from Toray T800 carbon fiber, making it lightweight yet durable enough for a few adventures. As for compliance, there are intentional chatter-eating seatstays and a unique seattube cluster that reminds me of the old GT Triple Triangle.\u00a0<\/p>\n

\"X-LAB<\/a><\/figure>\n

As for the technical bits, the GT8 boasts 55mm of tire clearance and will fit single- or double-ring front setups. The bottom bracket is a T47 threaded. If you\u2019re an “I’ll just add it to my bike”<\/em> kinda rider, you\u2019ll be stoked about the multiple mounting points on both the frame and fork. It’s not something that I look for in a frameset, but it makes a lot of sense for this bike.\u00a0<\/p>\n

The internal storage is ample, and fits a tool bag (or rain jacket) with some extra space. Plus, the look is clean carbon. The lever on the storage cover is very easy to use. It isn\u2019t over-engineered for aero-anything, just easy to flip with gloves on. <\/p>\n

Build Kit For The Long Haul<\/h3>\n

This is probably where the GT8 makes its best first impression.<\/em><\/p>\n

The drivetrain is Shimano GRX 715 1x Di2<\/a>, paired to a 10-51 cassette and a 40T chainring. That\u2019s a broad range and a smart one. It gives the bike enough top end for quick gravel\/road sectors and enough bailout gearing for steep, leg-breaking climbs that show up halfway through long events and bad ideas. <\/p>\n

X-LAB doesn\u2019t cut corners mixing and matching odd parts (minus the crankset), they just went with a dependable (IMO) Shimano groupset that will do most of the work out there. The GRX brakes are one of my favorites, and the 715 levers have that nice mix of road feel (and shape) without the longer reach of the dedicated GRX 820 levers.\u00a0<\/p>\n

Then there\u2019s the Branta alloy crankset with an integrated power meter. This thing looks very much like an SRAM XPLR crankset, even down to the chainring, but it’s not.\u00a0<\/p>\n

The power meter arrives with built-in Apple Find My functionality. Find My is one of those quietly smart additions that becomes a lot more interesting when your bike is sitting outside a coffee shop, hotel, or gas station. Love to see it. Plus, the\u00a0Branta alloy crankset comes with a rechargeable battery. The jury is still out on the unit’s longevity, but so far, so good.\u00a0<\/p>\n

Branta Everything <\/h3>\n

If you haven\u2019t realized it by now, Branta is X-LAB\/XDS’s in-house brand. Branta makes everything from wheels to cockpits to tires. <\/p>\n

\"X-LAB<\/a><\/figure>\n

The wheelset that comes on the X-LAB GT8 is the Branta C45 Gravel Carbon Wheelset. It’s nothing crazy, with steel spokes, a 45mm-deep carbon rim, and a tubeless setup. The wheels are much better (on paper) for what you\u2019d usually find spec\u2019d on a $3-4K gravel bike. They arrive with Continental Terra Trail 700x45c, a solid place to start for racing or exploring.<\/p>\n

\"X-LAB<\/a><\/figure>\n

The cockpit kit is all Branta. Starting with a uniquely designed carbon stem and Branta Gravel Carbon Handlebars. The seatpost is a standard round carbon 27.2mm seatpost, topped with a Fizik Terra Argo X7 saddle. <\/p>\n

\"X-LAB<\/a><\/figure>\n

The look of all the Branta kit is nice. Yeah – there is some dated 4K weave, but the overall presentation is nice. I was bummed the stem was shorter than my usual fit of 110-120mm. The semi-integrated setup will take me some time to switch up, but the 90mm stem length on the 54cm size should fit the majority of riders just fine. <\/p>\n

\"X-LAB<\/a><\/figure>\n

The bars will be narrow for some and right on for others (like for me). The 38mm bar width, paired with the slight flair, makes for a nice aero position. However, those used to riding wider might find it tight, especially while climbing. <\/p>\n

\"X-LAB<\/a><\/figure>\n

One thing that is missing is a UCI sticker of approval. Yes, not many bikes in the gravel world have them, but we\u2019re starting to see more as UCI enters the gravel discipline. So yeah, it’s not “100% approved for the gravel world championships”<\/em>, but the same goes with 75% of the gravel bikes out there. <\/p>\n

\"X-LAB<\/a><\/figure>\n

What’s Its Weight? <\/h3>\n

Claimed weight is 8.78kg \/ 19.31lb in a size M, and our ride came to 20.02lbs, which is pretty respectable for a non-race-focused gravel bike in a completely stock build.<\/p>\n

Pick Your Flavor<\/h3>\n

The GT8 is available in two color options: Afterburner Black and Slipstream (tested). Both versions are the same build and look slightly understated.<\/p>\n
