Riding & Racing at top speed
U.P. & U.P.PER. 2.0

10 years after the OPEN U.P. defined the gravel bike, we have perfected it with the U.P. 2.0 and superlight U.P.PER. 2.0

Highlights.

A light, nimble gravel bike for fast racing or riding. Even an overnighter or fast tarmac group rides are possible thanks to its comfort, efficiency and speed.

To ride faster & farther requires high comfort & low drag. The new frameset keeps OPEN's legendary frame compliance while adding aero where it matters.

Optimized for 35-46mm tires (44mm on the CONCE.PT) for the most responsive and fun handling possible on all terrain. To go even bigger, consider the WI.DE.

Full-carbon closed-shape design (no inserts or clamp cut) for optimal stiffness, strength & weight. 10 sizes, each can adjust stem length by 15mm in 5mm steps.

Made in Freedom - in Portugal. As entrepreneurs, we have a choice where to invest. And to us, cycling means freedom, so we invest accordingly.

Worry-free details such as a UDH hanger, a T47 threaded BB and internal routing with easy cockpit adjustments mean more riding and less wrenching.

Differences U.P. 2.0 & U.P.PER. 2.0.

Both frames are made in Portugal and tested to the same strength and stiffness standards. The U.P.PER 2.0 uses a different, ultralight layup, while the U.P. 2.0 is more affordable.

While both frames have cargo rivnuts for a toptube bag and under-the-BB storage, U.P. 2.0 has 3 extra rivnuts UNDER the toptube for a frame bag (various options coming).

The U.P. 2.0 comes in various colors, the U.P.PER 2.0 is always predominantly black. Both are available in Raw-Ready-to-paint for custom painting. Check here for all options.

Aero where it matters,
Comfort where it counts.

Aero matters most up-front (headtube, fork, bars, downtube), where airflow is still smooth. But aero is moot if the bike is too harsh to stay aero yourself on long rides. We optimize aero and compliance together, through tube design and carbon layup.

As we go further back on the frame, comfort always beats aero. The seattube, chainstay & seatstay shapes ensure the comfort OPEN is known for. As a bonus, the ultra-thin seatstays keep the frontal area small. They even get a micro-aero treatment.

OPEN B.A.R.
(Break All Rules).

One-piece bar-stems look nice and can be light, but lack adjustability. Enter the OPEN B.A.R., with its closed-form 100% carbon composite design. No threaded inserts or vertical cut for the clamping bolts, just continuous fibers for the best weight, stiffness & strength.

Even better, our patented internal clamp system lets you adjust stem length by 15mm in 5mm steps. Often you can even adjust the length without undoing the brake hoses.

With 10 different bars, there is always one perfect for you. Welcome to the OPEN B.A.R. Cheers!

Note: Previous generation OPEN frame riders will usually convert to the same frame size of the U.P.(PER). 2.0 with a 10mm shorter stem to compensate for the 10mm longer effective frame reach (ignore standard reach in the geometry chart for this purpose). So keep that in mind when selecting your OPEN B.A.R. size.

Fork options.

We love fork design, where tire clearance, steering geo, aerodynamics, compliance, cargo, braking efficiency all come together.
The U.P.(PER) 2.0 has 2 fork options, each in 5 sizes.

U-Turn Aero: our fastest option, optimized for aerodynamics. This means the blades are fully aero, the brake caliper is integrated and no cargo rivnuts or other details disturb the airflow. Standard on U.P.PER. 2.0 & U.P. 2.0.

U-Turn Adventure: our most comfortable fork, with shallower, more compliant blades. This fork is compatible with standard cargo cages and with the world's lightest cargo attachment system - patent pending. Coming 2026.

Design is in the details.

Deep headtube: The headtube is crucial for aerodynamics, as it is the first frame member to hit the airflow. The deep shape works wonders here, while underneath the carbon layup ensures the comfort stays high. A true win-win.

Straight chainstays: Offer the best power transfer yet still provide great tire clearance (up to 46mm - 44mm for the U.P.PER. CONCE.PT). As always, you should measure the tire when mounted on your rim, as the tire labels are not always accurate.

Wire-Stays: Thin seatstays provide compliance, while their bowed shape "pre-set" its flex for the best possible vibration absorption. For the new frames, the direction of the pre-set is rotated 90 degrees, so they bow out sideways instead of downward.

27.2mm round seatpost: The most boring seatpost size may not look like a design choice, but it is. It is light, offers great compliance and is compatible with a long list of seatposts, including many dropper and/or suspension posts should you desire to use one of those.

Size-specific crown: We vary the fork crown shape and height significantly from size to size, in order to create the best stiffness and compliance balance for each size. It also ensures the handling is equally agile in every size. This is a first in bike design.

T47: is the new standard for threaded BBs, embraced by the leading BB makers. It's spacious enough for any crank axle (oversized 30mm, SRAM DUB, Shimano, 24mm) and combine that with a wide 86mm BB shell to maximize the connection to the chainstays.

UDH: The new UP and UPPER are UDH compatible, meaning it can be paired with any standard drivetrain (SRAM, Shimano, Campagnolo, etc) using a UDH hanger and with SRAM Transmission rear derailleurs (direct-mount to the frame).

Rotoblock fender mounts: Standard fender mount are eyelets, which can cause the fender wires to flex and rotate (causing rattling and even rubbing). Our unique fender mounts thread directly into the frame, thereby eliminating any rotation and stiffening the setup.

Broadshoulder dropouts: Installing wheels with disc brakes and thru axles can be a real pain if the wheel isn't lined up correctly. With the extra broad shoulders on our dropouts (50-100% wider than standard), the wheel is much better supported.

Smartmount 160 front: Instead of the standard four bolts plus an adaptor to attach the brake caliper to the fork, OPEN pioneered the Smartmount direct-mount system that removes the adaptor and two bolts to attach the caliper directly onto the fork.

Smartmount 160 rear: The brake caliper attaches directly onto the frame, positioned for 160mm discs. No adaptors or spacers are required (unlike on standard flatmount setups that require these extra parts). This makes Smartmount lighter, stiffer & safer.

Made In Freedom

If we have to characterize what OPEN means to us in one word, it’s freedom. Ultimately that is the feeling we get when riding our bikes, and we hope you do too. For us personally, OPEN also represents freedom in a different way, free from the usual pressures of the (bike) business, of “new and improved” product launches and sales targets.

A few years ago, seeing everything that was happening in the world, we concluded that freedom needs to permeate everything we do at OPEN. While we are under no illusion that a tiny bike company can change the world, we simply didn't want to support anything "un-free" anymore.

To be very clear, we do this because WE want to do this. We hope you agree, but it's totally fine if you don't. This is not a virtue competition, everybody should run their lives and businesses as they see fit.

At the same time, we have been working for years on pushing production to the next level, with the MIN.D. California and several other projects. This all comes together in moving our frame production to our partner Carbonteam in Portugal. Their commitment, the production technology and the quality control are second to none, and the people are wonderful. So truly a win-win.

Recommended groupsets

For serious gravel and off-road (on any brand of bike), we recommend a rear derailleur with a clutch or cage damper for chain management. The U.P.(PER.) 2.0 is compatible with the following electronic groupsets:

- All SRAM AXS

- All Shimano GRX Di2

- Campagnolo Super Record 13 with nano clutch rear derailleur (RD02-SR13DHWRLC (max 36T for 2x or 1x fast) or RD02-SRX13WRL (max 48T))

Indoor trainer compatibility

We recommend Direct Drive indoor trainers only.

These are trainers where you remove the rear wheel of your bike and install the bike onto a cassette that is fixed onto the trainer.

Some of the most popular compatible Direct Drive indoor trainers are (but others may work too):

Wahoo KICKRmove, KICKR, KICKR 2, KICKRcore
Elite Justo 2, Rivo, Rivo Zwift cog&click, Avanti Zwift cog&click, Turno
Tacx Neo 2T, Neo 3M, Flux 2, Flux S

IMPORTANT:

Some trainers may require an adaptor to fit the frame. The U.P.(PER) 2.0 uses a 142x12 thru-axle with M12x1.0 thread.

These trainers are compatible with our FRAME, but you must check compatibility with your GROUPSET. For example, not all trainers are compatible with 13s cassettes or may require an adaptor.
