When Team Jumbo-Visma decided it was time to race XCO, they came to us for the answer. The ZHT-5 marks a new era for Cervelo and the team, as we go racing together. Our engineering expertise has already been proven in cyclocross (R5-CX) and gravel racing (Aspero), and now we've upped the ante and designed a mountain bike worthy of the Cervelo name. ZHT-5 is a Cervelo through and through: fast, efficient, and fun to ride. The 69-degree head tube angle, modern reach, and short chainstays combine to make a bike that's stable at speed and nimble enough for pack racing. There's room to maneuver in the cockpit, whether you're darting inside on an uphill hairpin, or hanging off the back to make time on the descent. SPEED FIRST - Our mantra is to make riders faster. And doing that means creating bikes that turn power into forward motion as efficiently as possible. Nothing does this more effectively in dirt than a hardtail. But power is nothing without control, so we focused on making a rapid cross-country race bike that still handles confidently in technical sections, feeding the desire to ride faster. STIFF, LIGHT & READY TO FIGHT - Weighing in at just 907g (size Medium), ZHT-5 is a featherweight fighter with the punchy turn of pace that only a hardtail can deliver. Decades of making frames built for the strongest sprinters in the world has fed into a super stiff mountain bike design that propels you to the front without compromising weight or ride quality. MODERN GEO FOR THE MODERN XC RIDER - If you've not ridden a hardtail for a while, you'll be surprised at how the ZHT-5's 69-degree head tube angle, 457mm reach (size L), and 430mm chainstays feel progressive and refreshingly modern. If you've ridden them all your life, you'll be baffled at how we've managed to eke out yet more performance from such a clean and simple design. The ZHT-5's geometry puts you in the driving seat to carve up all the tight hairpins and features that litter the ups and downs of today's XC trails. NOT OUR FIRST RODEO - We know from winning cyclo-cross World Champs that when the going gets gritty, threaded bottom brackets are the best way to go. ZHT-5 adopts the BSA threaded standard to meet the strength, stiffness, durability and serviceability needs of racers and race mechanics alike. It also makes it the ideal winter training companion.

The stock setup optimizes stability and roll-over speed, while a 27.5 rear wheel delivers a snappier feel and more saddle-to-tire clearance. Some riders favor this “mullet” setup for riding steep, technical terrain.

See You At The Bottom Even though Jekyll boasts a unique combo of go-fast tech that's never been seen before, it's not a bike that talks. It's a bike that goes. Where it thrives Steep, fast, rowdy mountains What it's built for Enduro racing, bike park sessions, high-speed mobbing Highlights - Full carbon frame, 165mm travel, Proportional Response Tuned - Fox Float Factory X2 Shock - Guidler-Idler pulley/chainguide system Descend into Greatness It's a hell of a climber but come on. Jekyll was born for the downs. Every part of it crafted for the sweet embrace of speed, every element designed to help you wring a bit more of velocity's nectar from those steep, chunky, high pucker lines you love. Best. Suspension. Ever. 4-bar meets high pivot meets idler pulley meets size-specific kinematics. For real. If you're not up for suspension buzzword bingo, just know that it grips, floats, and pedals like nothing else. It's always up for getting down. The Gravity Cavity The shock tucks cleanly into the twin spar downtube, keeping the bike's center of gravity as low as possible. Wicked stability, instant line changes and one-of-a-kind looks. Built for You Well, not you specifically. But someone just like you. With our Proportional Response design, everything—from the suspension layout to the geometry, even the length of the chainstays—is completely customized by size, for performance built just for you. Suspension Like No Other High main pivot gives it a bump-swallowing rearward axle path. The Guidler pulley kills the pedal kickback of high pivot systems. The 4-bar linkage keeps braking smooth, traction high and pedaling crisp. Guidler Idler pulley + chainguide = Guidler. Clever, right? Idler eliminates feedback from the high pivot swingarm, keeping your pedal stroke smooth, even when the terrain isn't. The guide, well, it guides. Suspension Built For You A rider's center of gravity drives how the suspension performs, yet most bikes use the exact same layout for all sizes. Proportional Response Suspension alters the design by size for truly next-level performance. Proportional Response Geometry Long, slack and low—and fully size-specific. As the front of the bike gets longer with each size, the chain stay length increases proportionally, keeping the rider centered between the wheels for true "made for you" handling. Guardhouse Downtube protector keeps your frame safe from roost and strikes, while letting water and debris pass through. The Ai Advantage Our Ai Offset Drivetrain delivers more tire and mud clearance in the swingarm, and more even spoke angles for a stiffer, stronger rear wheel.
