OPEN launches the U.P. 2.0 Adventure: Aerodynamics & Comfort meet Adventure

open U.P. 2.0 Adventure review — OPEN U.P. 2.0 Adventure

OPEN adds a new member to its Unbeaten Path family: the U.P. 2.0 Adventure. It takes the aerodynamics and comfort of the U.P.|U.P.PER. 2.0 frame and adds serious cargo capability and an even more comfortable fork.

The entire U.P.|U.P.PER. family is built around one goal: the fastest possible bike on any terrain. Aerodynamics matter — but so does comfort, because a fast position you can’t hold for hours is no position at all. Fit, handling geometry, tire optimization: everything works together.

The U.P. 2.0 Adventure takes all of that further.

Aerodynamics Meets Comfort

OPEN has always prioritized comfort — even though co-founder and technical director Gerard Vroomen spent his career designing aero bikes, going back to the founding of Cervélo.

“Aero without comfort is useless,” says Vroomen. “A harsh ride will compromise your position on long rides far more than aerodynamics can make up for. With the U.P. 2.0 we’ve added aero where it really works while relentlessly protecting frame comfort. The best of both worlds, genuinely.”

Adventure-Ready

OPEN customers use their bikes for everything from long day rides to multi-day expeditions. The U.P. 2.0 Adventure is built for both, without compromise.

“Light, simple, smart — those are our design principles,” says Vroomen. “We wanted to keep this a true U.P. — fast on any terrain — while also making it fully bikepacking-ready.”

The frame features three eyelets under the toptube for a strapless frame bag — OPEN was the first gravel brand to introduce this on the top of the toptube, now you can direct-mount a bag under the toptube too. Several custom bag makers can produce these, and later this year OPEN will offer a dedicated aero frame bag developed with Apidura.

The new U-Turn Adventure fork takes comfort further with a redesigned leg profile, then adds the world’s lightest cargo solution. Its slots let you strap a soft bag directly to the fork legs, using the fork structure itself as support. No cage required. Fit a bag with integrated straps or use separate cargo straps or bungee cords. Prefer a cage? The cargo barrels let you mount any standard cage to the fork.

OPEN A.I.R. Geometry – Agile | Integrated | Refined

A.I.R. is OPEN’s approach to making rider and bike work as one: agile steering that feels lively on any terrain, integrated components that work together with the frame geometry as a system, and superior adjustment options to refine your position for both comfort and aerodynamics.

As gravel riding evolves, so does OPEN’s approach to fit. The new frames are slightly longer and taller than their predecessors, reflecting how riders are pushing harder and further.

The steering geometry follows a consistent OPEN principle: the bike should feel as agile and lively as a road bike, despite running much larger, profiled tires. It’s an often-overlooked ingredient — but essential on mixed terrain. Every size U.P. 2.0 frame has its own geometry and tube shapes; every fork size is also individually tweaked to deliver that trademark OPEN handling at every size.

OPEN B.A.R.

Perfect fit doesn’t stop at the frame and fork — the cockpit matters just as much. The OPEN B.A.R. solves a problem most riders have quietly accepted: one-piece bars that don’t quite fit. Too few sizes, not enough adjustment, a position that’s always a compromise.

“It’s strange that riders obsess over 2.5mm in crank length or 5mm in saddle height, but stem lengths jump in 10mm increments,” says CEO Andy Kessler. “Our integrated bar fixes that.”

The OPEN B.A.R. comes in 10 sizes. Each bar allows you to fine-tune your stem length across a 15mm range with 5mm jumps. Adjustment takes seconds: loosen the clamps, flip the parts, tighten, done.

Adventure-Ready

OPEN customers use their bikes for everything from long day rides to multi-day expeditions. The U.P. 2.0 Adventure is built for both, without compromise.

“Light, simple, smart — those are our design principles,” says Vroomen. “We wanted to keep this a true U.P. — fast on any terrain — while also making it fully bikepacking-ready.”

Tire Clearance

OPEN broke open the gravel world over 10 years ago with the original U.P. — the first performance gravel bike. Since then, extensive tire testing for both rolling resistance and aerodynamics has pointed consistently to the same conclusion: 50mm is the valley of death — the worst of both worlds. Go to 45mm or smaller and aerodynamics work in your favor (especially with wide aero gravel rims). Go to 55mm or beyond and lower rolling resistance keeps your speed.

The gravel market has since developed an inexplicable obsession with 50mm tires. We hope it passes. Physics hasn’t changed.
OPEN’s model line serves you on either side of the 50mm divide. Up to 45mm, the U.P. 2.0 is your bike. For 55mm and beyond, the WI.DE. 2.0 is coming.

The U.P. 2.0 Adventure with 46mm maximum clearance stays true to that philosophy. It’s built for fast riding and agile handling, with or without cargo.

Availability & Pricing

The U.P. 2.0 Adventure is available now at opencycle.com/up-20-adventure and at select OPEN retailers. The launch color is Orange Pearl; the frame is also available in custom colors or as Raw Ready-to-Paint. It is offered as frameset and complete bike.
