KhodaaBloom KESIKI Geometry: What Stack and Reach Add to the Size Label
KhodaaBloom KESIKI geometry changes in more than one direction as its frame size increases. The saved chart lists stack and reach as separate rows: 559/369 mm for 420, 572/380 mm for 460, and 582/392 mm for 500. Keeping each pair together gives a more useful comparison than replacing the chart with Small, Medium and Large.
KhodaaBloom KESIKI geometry in three complete columns
The Japanese table labels stack as I and reach as J. For the middle 460 mm frame, that means I is 572 mm and J is 380 mm. Those values describe the charted frame, without specifying where a particular rider's hands or saddle will finish after assembly and adjustment.
The progression is not an equal change in both rows. Subtracting the published figures, 420 to 460 adds 13 mm of stack and 11 mm of reach. Moving from 460 to 500 adds 10 mm of stack and 12 mm of reach. These are calculations from the source table, rather than measurements taken from an assembled bicycle.
Use the other rows to explain the comparison
Effective horizontal top-tube lengths are 525, 545 and 565 mm across those same columns. Head-tube lengths are 100, 110 and 120 mm. Seat-tube angles change from 74.5 degrees to 74 degrees and then 73.5 degrees. Retaining the named rows prevents a single increasing number from becoming the entire explanation of the frame change.
The KESIKI in Dark Blue identifies the three offered size configurations being discussed. A frame chart is still different from a record of its complete cockpit: the published handlebar and stem have their own dimensions. Do not assume that a change in frame reach moves the hands by exactly the same amount.
A photograph locates tubes; the chart supplies dimensions
The different road bicycle pictured alongside this discussion makes its head tube, top tube and seat tube visible. Its oblique camera angle cannot supply a KESIKI stack or reach measurement. Use the actual geometry table when comparing numbers, rather than scaling a photograph or judging a frame from how long it looks.
A useful fitting question names the two KESIKI columns under consideration and the position you want to compare. Keep the source's millimetres and row letters in your notes. The existing brand introduction gives broader model context, while the KhodaaBloom topic groups related reading.
FAQ
What stack and reach does the 460 chart list?
It lists 572 mm of stack and 380 mm of reach.
Do both dimensions increase equally between sizes?
No. The changes calculated from the published rows differ.
Is frame reach a complete hand-position measurement?
No. The actual saddle, stem, handlebar and other fitted details still require their own information.
