OPEN Gravel Bikes
OPEN gravel bikes extend the brand’s performance DNA beyond paved roads, offering versatility, stability, and confidence across mixed terrain. With carbon frames and both 700c and 650b wheel options, these bikes are engineered for endurance rides, adventure touring, and performance-focused exploration. Each model brings a unique approach to gravel riding while sharing OPEN’s core principles: efficient power transfer, balanced handling, and geometry tuned for control on varied surfaces.
OPEN UP and UP 2.0 is a versatile endurance bike, built for adaptability across smooth roads and rugged paths. OPEN UPPER and UPPER 2.0 pushes performance further with an ultralight frame, ideal for extended gravel rides and racing-level responsiveness. OPEN WIDE emphasizes comfort and stability, accommodating wider tires up to 2.4" for bikepacking and long-distance adventure riding. All models feature carbon frames optimized for stiffness and lightweight efficiency, geometry designed to inspire confidence in corners and descents, and wheel sizing that adapts to terrain and rider preference.
From mixed-surface endurance to off-the-beaten-path adventure, OPEN gravel bikes combine innovative design with practical performance. Whether exploring remote trails or pushing the limits on challenging gravel courses, these bikes offer the control, comfort, and capability to go further.
From Smooth Roads to Rugged Paths
OPEN gravel bikes are designed to balance responsiveness with stability. Each model reflects a different approach to gravel performance:
OPEN UP
Ten years after defining gravel riding, with the OPEN UP. The UP 2.0 brings a updated take on the quintessential gravel bike deliver speed, comfort, and versatility. Carbon frames balance aero efficiency up front with compliant rear stays, while straight chainstays maximize power transfer. The adjustable OPEN B.A.R. handlebar/stem, 35–46mm tire clearance, internal routing, and UDH compatibility ensure performance and fit.
OPEN UPPER
The OPEN UPPER and UPPER 2.0 take gravel performance to the next level with ultralight carbon frames and responsive handling. Designed for riders seeking peak agility, these bikes balance aerodynamic efficiency up front with compliant rear stays for comfort on long rides. Adjustable OPEN B.A.R. handlebar/stems, 35–46mm tire clearance, internal routing, and UDH compatibility ensure precise fit and versatile performance across gravel, dirt, and fast tarmac.
OPEN WIDE
The OPEN WIDE is built for extreme gravel and mixed-terrain adventures, balancing big-tire capability with nimble handling. Its carbon frame accommodates 650b tires up to 2.4" or 700c tires up to 46mm, with double-dropped chainstays for stiffness, clearance, and responsive geometry. Internal routing, Smart-Mount 160 brakes, and multiple cargo mounts make it practical for long rides. Lightweight and versatile, the WIDE delivers comfort, control, and speed across rugged trails or fast gravel roads.

The OPEN MIND (MINimal Design) is what happens when one of cycling's most celebrated engineers builds the road bike he actually wants to ride. Designed by OPEN co-founder Gerard Vroomen, the MIND is a pure, purposeful carbon road bike that proves you don't need complexity to achieve something extraordinary, you just need to get every detail exactly right.
At the heart of the MIND is a philosophy of radical simplicity. Classic round-tube aesthetics hide genuinely sophisticated engineering: a 25mm continuous seat tube that eliminates the traditional seatpost junction entirely for remarkable all-day compliance, clearance for up to 33mm tires for confident grip on broken pavement, and OPEN's Smartmount direct brake attachment for a cleaner, lighter, stiffer setup throughout.
What makes the MIND special is how much ground it covers. Sharp enough to hunt KOMs and sprint out of corners, comfortable enough to tackle long mountain passes without punishment, and confident enough to handle the occasional gravel shortcut without missing a beat.
For riders who want a fast, beautiful, no-compromise road bike built to last a lifetime, the OPEN MIND is the one. If you're looking for something that can handle a little more off-road riding, check out the OPEN UP.
The OPEN UP is where it all began. When Gerard Vroomen and Andy Kessler set out to build the gravel bike they actually wanted to ride, the result was a genre-defining machine that rewrote the rulebook for what a drop-bar bike could do, and the cycling world hasn't been the same since.
The UP's genius lies in its radical versatility. Swap in a set of 700x28c road tires and it flies on tarmac. Mount up 32-40mm gravel tires and it eats mixed terrain for breakfast. Roll on 27.5x2.1" mountain bike rubber and it becomes a legitimate off-road weapon, all without changing a single thing about how the bike handles. The iconic dropped chainstay, one of the most copied features in modern bike design, makes it all possible, clearing massive tires while keeping road cranks and a narrow Q-factor for efficient pedaling.
The updated OPEN UP 2.0 builds on this proven formula with refined comfort and go-anywhere versatility optimized for long-haul adventures. With dual 700c and 650b wheel compatibility, clearance up to 2.1", and OPEN's signature lightweight carbon construction, the UP 2.0 is built for riders who want one bike that genuinely does it all, from forest service roads to multi-day bikepacking routes to fast weekend rides with friends.
The bike that started the gravel movement, now better than ever.
Looking for more tire clearance? Check out the OPEN WIDE.
If the OPEN UP wrote the rulebook for modern gravel bikes, the UPPER tears a few pages out and goes faster. Sharing the same proven geometry, tire clearance, and dual wheel compatibility as the UP, the UPPER distinguishes itself where it counts most: weight. A more complex, high-modulus carbon layup shaves 180 grams from the frame, delivering a snappier, more responsive ride that gravel racers and performance-focused riders will immediately feel on every climb and sprint. Flat-mount brakes, OPEN's Smartmount direct caliper attachment, and the iconic dropped chainstay round out a package that's as capable as it is refined, equally at home on a race start line or a fast weekend adventure.
The new UPPER 2.0 takes a decade of refinement and pushes it even further. Built in Portugal by OPEN's manufacturing partner Carbonteam, the UPPER 2.0 pairs an ultralight carbon layup with purposeful aerodynamic shaping where it matters, up front at the headtube, fork, and downtube, while maintaining the legendary frame compliance OPEN is known for in the rear. The revolutionary OPEN B.A.R. one-piece carbon handlebar and stem adds adjustable reach in precise 5mm increments, and compatibility with T47 threaded bottom brackets and UDH derailleur standards keeps maintenance simple. Optimized for 35-46mm tires, the UPPER 2.0 is built to race, ride, and explore, fast, efficient, and relentlessly capable.
For the rider who wants every possible edge without giving up an inch of versatility, the OPEN UPPER delivers.
The OPEN WIDE (Winding Detours) is built for riders who want to go further off the beaten path—and get there fast. Taking everything that made the legendary UP so revolutionary and pushing it deeper into adventure territory, the WIDE is OPEN's most capable off-road machine, designed for the kind of riding that would stop most bikes in their tracks.
The secret weapon is OPEN's double-dropped chainstay, an evolution of the single dropped stay that launched an entire category of bikes, creating a stiff, efficient box structure behind the bottom bracket that unlocks clearance for tires up to 2.4" on 650b wheels or 46mm on 700c. That means rutted singletrack, slippery roots, chunky rocks, and remote backcountry roads all fall within reach. And yet, thanks to OPEN's performance geometry and narrow Q-factor, the WIDE remains deceptively quick on pavement, something that never fails to surprise first-time riders.
Beyond the tires, the WIDE is purpose-built for adventure. A fourth bottle cage mount under the bottom bracket, strapless top tube bag mounts, and compatibility with frame, handlebar, and saddle bags make it a legitimate bikepacking rig. A slightly taller headtube and lower bottom bracket versus the UP add stability on technical terrain without sacrificing the nimble, road-bike-like handling OPEN is known for.
Fast enough for the road, fearless enough for the trail, the OPEN WIDE is the ultimate one-bike quiver for adventure riders.
