Product description
MODERN CLASSIC
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.
WHAT IS THE MIN.D.?
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)
Available in standard 2x and dedicated 1x version
Classic, understated look in both shaping and color
TWO VERSIONS
The MIN.D. comes in two versions: standard and California. Same geometry, same functionality, but the latter is - you guessed it - Made In California at the Project California facility.
This R&D facility with a small factory was set up back in the day when Gerard was co-founder/owner of Cervélo. It resulted in both the R5CA and RCA models, two road frames that redefined lightweight bike frame production.
The facility’s owner/operator Don Guichard and Gerard have stayed in touch since. So when Don wanted to do a bike project again, we decided to go on a new journey to make something special.
While the two frames have a lot in common, the completely new tools and processes used in California result in a frame that is around 75 grams lighter yet stiffer in all directions except in the continuous seattube (where it actually provides even more flex than the original MIN.D. This combination makes the ride something very special.

1 | Estimates; for accuracy use stack/reach of your current gravel/road bike or a fit session. |
2 | Maximum when using 5mm spacer, giving 10mm safety margin on top (30mm margin with MOCT seattube top clamp). Assuming 40mm rail-to-saddle deck (40-45mm is standard for most saddles). |
3 | Standover to the top of the toptube directly above the BB (varies with tire size). |
4 | Normalized dimensions to compare to frames with standard (non-zero-offset) seattubes. |
5 | The length of seatmast needed to install a Shimano Di2 Battery results in this minimum achievable saddle height (including safety margin). |
