OPEN MIN.D California Frameset RTP
OPEN MIN.D California Frameset RTP
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.

| 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). |
