Cervelo
ZHT-5GX Eagle
The Cervelo ZHT-5 is a dedicated cross-country race hardtail built to support World Cup ambitions. As the brand's first mountain bike, it applies Cervelo's extensive road and gravel engineering experience to a lightweight carbon 29er platform. Designed around a 100mm-travel fork, the frame prioritizes direct power transfer and climbing efficiency without resorting to an overly punishing ride quality.
Visually defined by its clean lines and headset-routed cables, the ZHT-5 utilizes a 73mm threaded bottom bracket, SRAM UDH compatibility, and a 30.9mm seatpost diameter. While it ships with a rigid carbon or alloy post across the build range, the frame is fully provisioned for internal dropper routing. It is a purpose-built machine aimed squarely at competitive XC racers and endurance riders who want a highly efficient, responsive hardtail that manages fatigue over long distances.

Geometry & fit.
4 sizes published.
The ZHT-5 utilizes a geometry approach that avoids the extreme long and slack trends seen on modern trail bikes, sticking instead to numbers optimized for the tight confines of cross-country race courses. A 69-degree head tube angle keeps the steering agile and responsive, allowing the rider to easily hook the front wheel into tight uphill switchbacks.
To balance that quick steering, Cervelo pairs the front end with a relatively generous reach—measuring 457mm on a size large—and a mid-length stem. This stretches the rider into a powerful, forward-leaning posture that maximizes pedaling efficiency while adding high-speed stability. The 74-degree seat tube angle places the rider squarely over the bottom bracket for seated climbing.
Across all four frame sizes, the chainstays remain a constant 430mm. This compact rear center keeps the bike snappy out of corners and easy to maneuver through technical sections. The overall fit is decidedly aggressive and race-oriented, demanding an active riding style but rewarding the rider with precise, predictable handling.
Where the handlebar sits relative to the bottom bracket — the single most important fit pair.

The lineup.
4 builds, ranging $4,000 – $9,500.
The ZHT-5 lineup spans four distinct builds, all utilizing the same carbon frame. The range splits cleanly between premium wireless electronic setups and more accessible mechanical or entry-level wireless options.
At the top end, the XX SL AXS and XX1 AXS builds feature RockShox SID SL Ultimate forks and Reserve 28 XC carbon wheels. The XX SL model uses DT Swiss 350 hubs, while the XX1 version rolls on Industry Nine 1/1 hubs. Both top-tier models are equipped with carbon handlebars and Cervelo's own carbon seatpost, keeping overall weight to a minimum for dedicated racers.
The lower half of the ladder includes the GX Eagle AXS and mechanical GX Eagle builds. These models step down to a RockShox SID SL Select fork and alloy Race Face ARC Offset 27 wheels laced to DT Swiss 370 hubs. The cockpits also shift to alloy handlebars and seatposts. While these GX builds carry a slight weight penalty compared to the flagship models, they offer the same frame technology and geometry at a significantly lower price point, making them a practical entry point for privateer racers.
From the press.
7 reviews from the cycling press.
Reviewers consistently praise the ZHT-5 for balancing the explosive acceleration expected of a race hardtail with a surprising degree of compliance. Rather than chasing the absolute lightest or stiffest frame possible, Cervelo engineered the carbon layup and tube shapes to isolate the rider from trail buzz. This approach yields "remarkably little chatter, slap and back snapping" (Mountain Bike Rider) coming through the frame, even under heavy pedaling loads.
On the trail, this engineered flex translates directly to improved rear-wheel grip and momentum retention. Testers noted that the bike "carries a bit more speed over bumps" (YouTube) than a traditional rigid race frame, allowing riders to maintain traction over roots and loose climbs. The resulting ride quality is frequently described as a "fatigue soothing flow" (Mountain Bike Rider), helping racers stay fresh late into a marathon event or multi-lap effort.
While the handling is sharp and responsive, it avoids feeling overly nervous. The front end tracks predictably through tight corners, and the frame's ability to absorb micro-impacts keeps the bike composed on rougher descents. However, reviewers point out that the stock rigid seatpost limits the bike's capability on steep, plunging terrain, and the headset-routed cables can complicate maintenance. Despite these minor tradeoffs, the consensus points to a highly refined race bike that delivers "forgiving traction over just brutal torque delivery" (YouTube).
