OPEN MIN.D Road Frameset - Midnight Blue
This is a very different OPEN yet it answers the same question: What do we want to ride? While we love pushing the envelope, we 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 we wanted to ride.
- A high performance road bike frame using OPEN’s ultra-efficient tube shaping for power transfer, low weight & high strength
- Continuous seattube design for extreme comfort without gimmicks
- Tire clearance for modern road tires up to 32mm (since tire labelling is unreliable, always check tire clearance with the frame)
- Classic, understated look in both shaping and color
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. A comfortable fit geometry comes first. Our aim is sportive (we still want to go fast) but with a realistic saddle-to-handlebar drop and reach. Secondly, 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 comfort boost while also improving rolling resistance and grip. Finally, we create comfort through the frame shape and layup, in particular the seattube/seatmast and the seatstays.
The continuous seattube 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/seattube overlap at the toptube also means the seattube compliance continues uninterrupted. Our own minimalist seattube top clamp is nearly invisible yet easily adjustable by 0-15mm and slip-proof. We even have our 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.
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 adaptors, 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, 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”.
Vertically thin chainstays and seatstays provide compliance, while their lateral width and layup ensure rock-solid propulsion. Truly the best of both worlds.
MINIMALIST TOP CLAMP
OPEN-custom seattube top clamp with micro-wedge is barely visible, just the two countersunk set screws reveal the adjustment mechanism.
RITCHEY RAIL CLAMP
Clean, simple, hassle-free, that’s why the Ritchey system is so popular. The MIN.D. comes standard with the side plates for round 7mm and 7x9.6mm oval rails.
The MIN.D, internal routing is designed for electronic groupsets from SRAM, Shimano and Campagnolo.
This design uses the same threads to hold the thru-axle and lock the derailleur hanger into the frame. Simpler, lighter, optimized for the stiffest thru-axle: Syntace X-12.
Flatmount brake calipers attach directly onto the fork & frame, positioned for 160mm discs. No front or rear adaptors/spacers required.
Recommended groupsets: Any Shimano, SRAM & Campagnolo 1x, Any Shimano Di2, Any SRAM eTap, Campagnolo 2x EPS
BB standard: BB386EVO pressfit 86.5x46mm BB shell
Front derailleur mount: Yes
Rear thru-axle: 142x12mm superlight Carbon-Ti X-12
Front thru-axle: 100x12mm superlight Carbon-Ti X-12
Front/Rear disc rotor size: 160mm only
MultiStop internal system: Di2, eTap, EPS, 1x mechanical (all groups)
Headset: Cane Creek Integrated IS42/28.6 | OPEN-custom Integrated IS47/38
Seatpost: Integrated mast 25mm BB to saddle
Seattube top clamp: OPEN-custom saddle top clamp with micro-wedge for 25mm seat mast with 15mm adjustment (MOCT top clamp with 15-35mm adjustment available separately)
Rail clamp: Ritchey rail clamp with side plates for round 7x7 and oval 7x9.6mm rails included
Travel Bag Recommendation: Scicon AeroComfort Road 3.0. Scicon has an easy WILL YOUR BIKE FIT tool. (use your current bike setup for dimensions A, B & D and use the wheelbase in our geometry chart below for dimension C).
