Modern Classic.
The joy of riding starts even before the first pedal stroke, as its lightness, sleek appearance and midnight blue sheen with subtle color accents put a smile on your face.
On the bike, you experience a rare mix of performance and comfort. Every gram has a function. Beyond it is nothing, except endless roads unknown.
The MIN.D. (MINimal Design); it exists because it’s the road bike we want to ride.
What's on our MIN.D.?
Comfort.
Comfort is not about gimmicks, elastomers, electronic suspension or sub-atomic vibration damping graphene-infused nano-particles. It’s about finding ways to ride further, for longer, while enjoying it.
Continuous Seattube.
The extremely slender 25mm* continuous seattube adds astonishing comfort to the frame.
* 30mm is normally the minimum if you want to fit in the thinnest available (27.2mm) seatpost.
Our carbon layup.
So many marketing claims about carb on. But the truth is quite simple.
R–Turn.
OPEN was the first to truly optimize a fork for flatmount brakes with its Smartmount connection.
Standard, the bike industry uses four bolts plus an adaptor to attach the brake caliper to the fork. This allows for flipping between 140mm and 160mm rotors.
However, SRAM and Shimano both always recommend 160mm for the front, so we remove the adaptor and two bolts to attach the caliper directly onto the fork for that rotor size.
This makes the setup lighter, stiffer, safer. (Check our Specifications for the correct bolt lengths for each setup.)
This design also cleans up the R-Turn fork legs and allows us to make a very light structure with very tunable stiffness and strength.
Simplicity.
This is the essence of the MIN.D. As Dieter Rams said: “As little design as possible.”*
Design is in the details.
Reviews & Awards
“Open MIN.D Is a Road Bike Like Few Others. Why I fell for this radically conventional road bike: Radially conventional light and stiff frame, Long-ride geometry ideal for going up and down big-mountain passes, Throwback round tubes give it a pleasing ride on rougher roads”
– Bicycling
“MIN.D. California: A purist’s absolute dream bike, stiff, light with superb handling and classic, minimalist looks. But you’re gonna have to pay.”
– Cyclist
“The MIN.D. is focussed on what's important: having fun riding! As a modern road bike all-rounder, the MIN.D isn't above hunting down KOMs or an outing on the next forest track. The agile and playful handling in combination with its sprinting abilities make it a fun machine on winding roads. The continuous seat tube, which removes the need for a traditional seatpost and clamp, has a lot of compliance, and together with the 700 x 32C wide Schwalbe Pro One tires and a moderately stretched riding position, contributes to a very balanced level of comfort.”
– Design & Innovation Award
“The OPEN MIN.D. is a harmonious road bike concept that sensibly combines classic and minimalist aesthetics with modern technology. The bike isn’t as revolutionary as the UP, but it strikes a perfect balanced between sportiness and comfort, whether on asphalt or the occasional gravel road short-cut. If you appreciate extravagant yet understated design, prefer agile handling and don’t want to commit yourself to a single type of terrain or distance, the frame set of the OPEN MIN.D. will make a good basis for your dream bike.”
– Granfondo
“Besides spot-on handling, most impressive was how designer Gerard Vroomen was able to suffuse such modern-day performance and technology into a veritable less-is-more, package. Between the 25mm integrated seat tube, room for 32mm ties, small diameter tubes and subtle, multi-colored flare inside the forks and seatstays, the Open checked all the boxes.”
– RoadBikeAction Editor’s Choice - Best Road Bike
“Its combination of characteristics made the bike a delight to ride around the narrow, technical lanes I’m lucky to live amongst. The Min.D was light enough to make their 20% gradients manageable and stable enough to pilot down twisting, narrow descents with confidence. Plus the often broken road surface was no match for the bike’s big tyres. In short the Min.D has opened up new avenues and in so doing made riding a road bike a pleasure for me once again.”
– Cyclist Best of the Best - Endurance bikes
“Brilliant frameset for fast climbing, and it's comfortable too. Overall, the Open MIN.D is absolutely fantastic. It balances stiffness with comfort that can really be felt on rough roads. The handling is razor sharp, making this a fun bike to ride both uphill and back down.”
