The Time ADHX 45 is a premium gravel race frame designed to bridge the gap between fast road efficiency and mid-volume off-road capability. Evolving from Time’s original all-road platform, this generation expands tire clearance to 45 millimeters, opening the door to rougher terrain without abandoning the brand's racing heritage. At the core of the frame is Time’s signature Braided Carbon Structure and Resin Transfer Molding process, which weaves continuous fibers—including high-strength Dyneema—into a seamless chassis. This approach prioritizes structural integrity and vibration damping over absolute weight savings. Positioned for riders who value European craftsmanship and long-term durability, the ADHX 45 serves as a highly adaptable foundation. It suits the privateer racer or the dedicated enthusiast looking for a single, sophisticated platform that can transition seamlessly from smooth dirt to chunky logging roads.

Geometry & fit.
5 sizes published.
To accommodate larger tires while maintaining a performance-oriented feel, Time implemented targeted geometry adjustments for the ADHX 45. Compared to the standard ADHX, this frame features a slightly longer wheelbase, driven by 430-millimeter chainstays and an increased fork offset. These changes stretch the bike's footprint just enough to improve high-speed stability and traction on loose descents, without turning the handling into a slow, touring-style cruiser.
Rider posture leans toward an endurance-race fit—aggressive enough for fast group rides but upright enough to mitigate fatigue during long days on mixed surfaces. The cockpit relies on the FSA ACR integrated system, which routes all brake hoses internally through the handlebars, stem, and headset. This creates a sleek profile and prevents snagging, though it strictly limits stem and spacer adjustability once the bike is built. At the rear, Time opts for a traditional 27.2-millimeter seatpost secured by a standard external clamp, a straightforward design that ensures reliable saddle height without the slipping issues sometimes associated with internal wedges.

The lineup.
5 builds, ranging $6,290 – $8,740.
The ADHX 45 lineup spans five complete builds, ranging from premium mechanical setups to flagship electronic groupsets. Because the frame utilizes a modular cover system, it cleanly accommodates both single and double chainring configurations.
The ladder begins with Shimano GRX 12-speed mechanical builds in either 1x or 2x formats. These entry points deliver reliable, tactile shifting and share the exact same Dyneema-enhanced carbon frame and Kevlar-reinforced fork as the top-tier models. Moving up the range introduces electronic shifting with SRAM Force AXS 2x and Shimano GRX Di2, both offering precise gear changes that remain unaffected by mud or cable contamination. At the top, the SRAM Red XPLR 1x build maximizes weight savings and drivetrain simplicity for dedicated gravel racing.
Across all builds, riders can select from a menu of wheelsets, including alloy options from Boyd or carbon upgrades from Vision and Mavic, all wrapped in 45-millimeter Vittoria tires. While the entry price is undeniably steep, the value of the ADHX 45 lies in its boutique manufacturing, forged carbon hardware, and a lifetime frame warranty that provides long-term security for a high-end investment.
From the press.
8 reviews from the cycling press.
Reviewers consistently praise the ADHX 45 for delivering a highly refined ride that balances stiffness under power with exceptional vibration absorption. Testers note that the woven carbon construction effectively manages high-frequency chatter, with one rider observing that the frame manages to "dampen rocks, potholes, and other 'dings'" on rough logging roads (Blog). Despite the increased tire volume and lengthened chassis, the bike retains a snappy, efficient character. Multiple sources highlight that it maintains "road bike-like acceleration" during hard efforts out of the saddle (YouTube).
When navigating technical terrain or fast descents, the steering is frequently described as predictable and "intuitive to handle" (Blog), avoiding the nervous twitchiness of pure road bikes and the sluggishness of ultra-slack adventure rigs. Testers found that dropping tire pressures on the 45-millimeter rubber further enhances the "sublime ride quality" over long distances (YouTube).
The primary tradeoff noted by reviewers centers on the fully integrated front end. While the hidden cables create a clean aesthetic, the routing through the headset bearings complicates home maintenance. Additionally, while the frame itself proved highly durable in muddy and abrasive conditions, a few testers experienced minor frustrations with third-party electronic accessories. Overall, the consensus points to a beautifully finished, highly capable machine that rewards skilled input.
