Arcadex AL GRX 610 12sp

The Arcadex geometry points clearly to stable, endurance-oriented gravel handling rather than quick cyclocross-style responses. Across sizes XS to XL, head tube angles run from 70.5 to 71.5 degrees, paired with 430 mm chainstays on most sizes and a 75 mm bottom bracket drop. Those numbers suggest a bike that should feel planted on descents and composed on loose surfaces, with the longer rear center and lower bottom bracket helping calm the bike when loaded with bags or ridden on rougher terrain. Wheelbase is correspondingly generous, from 1020 mm in XS to 1077 mm in XL, reinforcing that emphasis on straight-line stability.

Fit has been modernized with relatively longer reach numbers for an adventure gravel bike: 376 mm in XS, 383 mm in SM, 391 mm in MD, 402 mm in LG, and 410 mm in XL. Stack remains fairly generous, from 544 mm to 638 mm, so the overall position should still suit riders looking for an endurance posture rather than an aggressive race setup. The steeper seat tube angles on smaller sizes, up to 74.5 degrees in XS, help keep rider weight centered as front centers grow, while the slightly slacker 73-degree seat angle on XL avoids over-compressing taller riders. One geometry table entry lists the XL chainstay as "432432," which appears to be a data error, but the intended figure is likely in line with the rest of the range.
