Arcadex Comp Apex Eagle D1 12sp

The 2024-on Bianchi Arcadex is a substantial repositioning of the model toward adventure riding and light bikepacking rather than pure all-road gravel. The key update is IFS internal frame storage in the down tube, which gives the bike a built-in place for tools and ride essentials without relying entirely on bags. That change is paired with more practical off-road capacity: tire clearance increases to 700x50 mm, or 45 mm with clip-on fenders, making the new Arcadex notably better suited to rougher tracks, longer mixed-surface routes, and loaded riding than the previous version.

Bianchi has also updated the platform around current gravel standards and fit expectations. The frame is now 1x-only, uses a UDH rear dropout, routes cables fully internally through an Acros headset, and keeps a BB86 press-fit bottom bracket with a 27.2 mm round seatpost secured by a wedge clamp. Geometry revisions push reach longer across the size range, while slightly longer chainstays and wheelbase aim to preserve the brand's endurance-oriented handling under load. In the market, that places the Arcadex closer to the stable, high-clearance adventure end of carbon gravel, rather than the racier side of the category.

Fit and geometry

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.

Builds

The Arcadex range spans both carbon and aluminum versions and is offered in five builds: Comp GRX 610 12-speed, Pro Rival XPLR AXS E1 12-speed, Comp Apex Eagle D1 12-speed, AL GRX 610 12-speed, and Pro GRX 820/822 Disc 1x12-speed. Even without pricing provided here, the lineup is clearly structured around material and drivetrain level, with the aluminum GRX 610 bike serving as the more accessible entry point and the Pro models occupying the higher-spec end of the range.

The main differences center on drivetrain tier and cockpit integration. Shimano GRX 610 and SRAM Apex Eagle builds target practical mid-range buyers, while the Pro builds step up to either wireless SRAM Rival XPLR AXS E1 or higher-end Shimano GRX 820/822. Bianchi also differentiates the front-end treatment: Pro models use a cleaner fully hidden cockpit setup, while Comp builds retain a semi-integrated arrangement. Across the range, the 1x-only frame design aligns with the bike's adventure brief, prioritizing simplicity, tire clearance, and compatibility with modern gravel and mixed-terrain gearing.
