Kona Dew Deluxe geometry: why a medium changed between archive years

Kona Dew Deluxe geometry needs a year and a size column to become useful. The official 2016 archive offers six sizes, while the 2021 entry offers four. Even the familiar medium label leads to different published measurements. Compare those numbers before assuming that a previously comfortable medium will describe another historical Dew Deluxe.

Locate Kona Dew Deluxe geometry by the full size label

For 2016 the labels are S46, S/M48, M52, M/L55, L57 and XL59. The medium column gives 401 millimetres of reach, 592 millimetres of stack and 750 millimetres of standover. Its seat-tube length is 520 millimetres and its head-tube length is 160 millimetres. Keep all of those values attached to the M52 column.

The 2021 size sequence is S, M, L and XL. Medium has 423 millimetres of reach, 607 millimetres of stack and 722 millimetres of standover. Those reach and stack figures are respectively 22 and 15 millimetres above the 2016 medium values. The shared letter does not describe an unchanged frame outline.

Compare neighbouring columns without inventing an equivalent size

The 2021 small has reach 398 and stack 569 millimetres. Its reach is close to the older medium's 401, but its stack is 23 millimetres lower. This illustrates why selecting whichever new column has the nearest reach can leave another important measurement different. It does not establish that a 2021 small replaces a 2016 medium.

Write the two complete columns beside one another, marking the dimensions that affect your own comparison. Reach and stack describe the frame reference, whereas the actual handlebar position also depends on the fitted cockpit. A geometry chart alone cannot establish your preferred position or the adjustments available on an unknown used bicycle.

The danger of relying on one number is also visible at the larger end of the older chart. The 2016 XL has reach 425 millimetres, close to the later medium's 423, but stack is 648 rather than 607. That is a 41-millimetre stack difference despite the similar reach. Neither the nearest number nor the familiar letter creates a direct size conversion.

Turn the chart into a fitting question

Confirm the actual frame's size marking and year evidence first. Then compare the published standover information with a physical check of the bicycle and your ability to get on and off comfortably. If a seller provides only a letter, request the missing identification rather than choosing a convenient archive column.

For Kona Dew Deluxe geometry, the useful result is a shortlist of measurements to check in person, not an automatic height-to-size prescription. The accompanying 2010 photograph establishes neither frame size nor a match to these later charts. A fit assessment can account for your proportions, riding position and the actual stem, bar and saddle arrangement after the correct frame has been identified.

FAQ

Are the two medium columns identical?

No. The selected 2016 medium lists reach401/stack592; the 2021 medium lists reach423/stack607, in millimetres.

Does a close reach figure prove the same fit?

No. Compare stack, standover and the complete bicycle's contact-point arrangement as well as reach.

Is the 2021 small equivalent to the 2016 medium?

No. Their reach figures are close at 398 and 401 millimetres, but stack is 569 versus 592. That similarity cannot establish equivalent fit.

Equipment can also change between frames: the Dew Deluxe mounting provisions and included accessories explains the practical inventory questions. Find further articles under the Kona topic.
