This is a very different OPEN, yet it answers the same question: What do we want to ride? While they love pushing the envelope, they also love the classic bike aesthetic. In the MIN.D., both come together.

The joy of cycling starts even before the first pedal stroke. As you collect your MIN.D., feel its lightness, admire the sleek tube profiles, see the shimmering midnight blue, smile at the splash of color from the 4 OPEN logo colors fading into each other on the inside of the fork and chainstays.

Once on the bike, a strange combination of performance and comfort becomes apparent. Every gram of material has a function. Beyond it is nothing, other than the endless draw of roads unknown. This is the MIN.D. (MINimal Design); it exists because it’s the road bike they wanted to ride.

• A high performance road bike frame using OPEN’s ultra-efficient tube shaping for power transfer, low weight & high strength
• Continuous seat tube design for extreme comfort, without gimmicks
• Tire clearance for modern road tires up to 32mm (since tire labeling is unreliable, always check tire clearance with the frame)
• Classic, understated look in both shaping and color

So much is said about comfort, but it’s not about gimmicks, elastomers, electronic suspension or sub-atomic vibration damping graphene-infused nano-particles. Comfort is about finding ways to ride further, for longer, while enjoying it.

That means first of all a comfortable geometry, something they worked hard at on their last generations of gravel bikes and have transferred back to the MIN.D. Our fit geometry is sportive (we still want to go fast), but with a realistic saddle-to-handlebar drop and reach. Our steering geometry is different from the traditional road bike standard, coupling agile handling to rock-solid stability.

Second, comfort means space for large road tires. Bad roads are one of the worst comfort killers, whether through cracks and potholes, or simply through vibrations. Making your tires a tad larger is the most effective solution, with the added benefit of lower rolling resistance and better grip.

Finally, they create comfort through the frame, in particular the seattube/seatmast.

Continuous Seat Tube
The continuous seat tube design is extremely small at 25mm diameter (30mm is normally the minimum if you want to fit in a 27.2mm seatpost). This change adds astonishing comfort to the frame. Removing the seatpost/seat tube overlap at the top tube also means the seat tube compliance continues uninterrupted.

Their proprietary minimalist seat tube top clamp is nearly invisible yet easily adjustable by 0-15mm and slip-proof. They even have their special MOCT saddle clamp (Measure Once Cut Twice) which is adjustable from 15-35mm. This also makes it much easier to resell your frame later on, although you probably never want to lose your MIN.D.

U-TURN FORK
The OPEN U-Turn was the first fork truly optimized for flatmount brakes by deleting the standard adaptor to switch between 140mm and 160mm disc rotors (you should always use 160mm rotors anyway for added safety & control at almost no extra weight). The adaptor is a feature without a benefit at the expense of weight, stiffness and complexity.

The R-Turn uses the same Smartmount direct-mount design with thru-bolts without adapters, just like the rear brake. Together with new shaping and a new layup optimized for road, the R-Turn is the lightest disc brake road fork available.

Note: For SRAM or Shimano, simply remove the adaptor and use bolts recommended for a 30mm “rear chainstay thickness.” For Campagnolo, use a “140 mm REAR" disc caliper with bolts “for 30-34 mm rear mount.” Or just let us build it for you, and rest assured that it's correct.
