Adjustable trail geometry A three-position Maestro flip chip lets riders dial in frame geometry for their riding style and terrain. The high setting adds more ground clearance, a good option for tight, technical terrain. In the low setting, the head tube gets slacker and the bottom bracket drops, ideal for confident handling at higher speeds. The middle position is neutral. In addition, a new headset flip chip adjusts reach so that riders can easily achieve their preferred positioning. Rear wheel options All models come with 29-inch front and rear wheels, but the flip chip lets you opt for a mixed wheel setup including a 27.5 rear.

Progressive but racy, ZFS-5 was built for today's evolving XCO courses - it has to pedal well and handle quickly, but also take on the chunks, jumps, and drops littering the circuit. ZFS-5's 67.8-degree head tube angle delivers the precision required for elbow-to-elbow hole shot sprints, and the confidence to let off the brakes when the track gets rough. And in 120mm-outfitting, the 66.6-degree head angle will give you the extra confidence to push harder and ride faster, even when the trail gets a bit...hellish. - Flat Bars, Suspension, Cervelo? World Cup season is here, and we’re all in. The Z bikes—the ZHT-5 and the ZFS-5, our hardtail, and full-suspension, respectively—made their race debut at the Nove Mesto World Cup. The pilots? World Cup veteran and former Dutch National XCO Champion Milan Vader alongside reigning Cyclocross World Champion Fem van Empel. - Call It A Comeback Milan Vader is a veteran XC racer and former Dutch National Champion. He was set to race the Z bikes in 2022, but a life-changing crash at Itzulia Basque Country meant his priorities were re-learning to walk and ride. He’s recovered phenomenally well and much faster than the doctors expected and will be racing the entire World Cup circuit this year. - Double Dutch Fem van Empel is one of Team Jumbo-Visma’s most recent signings, and she’s already made the rainbow connection. Following a decisive World Cyclocross Championships win in Hoogerheide, she traded knobbies for slicks this Spring and has now set her sights on improving her best-ever World Cup results and landing on the podium.
