Grava Adventure Co. - X-LAB GT8 First Ride Review | This Bike Doesn’t Make Sense for $3,199

After unboxing the X-LAB GT8, it was time to stop talking about specs and actually put this bike through its paces on my local gravel test loop in Reading, Pennsylvania.

This route includes pavement, rail trail, technical rocky climbing, fast gravel descents, and high-speed road sections—giving me a good feel for where the GT8 fits among bikes like the Specialized Crux, Trek Checkpoint, Giant Revolt, Pivot Vault, Santa Cruz Stigmata, Argon 18 Dark Matter, and more.

What surprised me most? The GT8 doesn't fit neatly into the "race gravel" or "adventure gravel" categories. It sits somewhere in the middle, making it one of the most versatile gravel frames I've ridden.

At $3,199, the value proposition is almost impossible to ignore:
✔ Shimano GRX 715 Di2 Electronic Shifting
✔ Carbon Wheelset
✔ Carbon Cockpit
✔ Power Meter Included
✔ Carbon Frame & Fork

But how does it actually ride?

Let's find out.
