There is no table that says «your weight, your spoke count»: searched across seven scientific databases and the manufacturers' own documentation, none turned one up. What DT Swiss does publish is system weight: the maximum permissible static wheel load is 60 % of the hub's maximum system weight, which runs from 110 kg on the XR 1700 Spline to 140 kg on the FR 1500 Classic and 180 kg on the HU 1900 Spline, for load and motor. Spoke count itself is a workshop judgment call, not a formula derived from weight.
You go looking for the weight-to-spoke-count table and it isn't there: the manufacturer bounds the wheel by system weight, not by spoke count.
It was searched across ScienceDirect, Springer, MDPI, Taylor & Francis, IOP, ASME and SAE, plus the manufacturers' technical documentation. Nothing. Not one publication, manufacturer or academic, crosses rider weight against a recommended spoke count.
What does exist, and what actually answers the question, is that the industry bounds the wheel by system weight. Spoke count comes afterward, as part of a workshop decision that combines that limit with the use category.
The user manual states it precisely: «the maximum permissible static wheel load is 60% of the maximum system weight». System weight is rider plus bike plus equipment plus luggage, and the 60 % is what a single wheel can be asked to carry under static load.
That maximum changes by hub. The XR 1700 Spline allows 110 kg of system weight, the FR 1500 Classic 140 kg, and the HU 1900 Spline reaches 180 kg, the highest of the three and the only one built for load and e-bike motor.
DT Swiss doesn't classify by weight alone: it classifies use into five ASTM categories, from paved road to downhill and freeride. Each hub is certified within its category, and that category actually drives the wheel choice more than a lone kilogram figure.
A light rider in a demanding category calls for a different wheel than a heavy rider on smooth road. System weight is a ceiling, not a recipe: two wheels sharing the same 110 kg cap can be built for entirely different jobs.
From workshop judgment, not from a formula that steps down from system weight to a spoke count. The only documented thing about the count itself is geometric: the hard limit is that crosses stay under a quarter of the total spoke count, and in the workshop that margin gets used tighter still, up to 3 crosses on 24-spoke wheels and up to 4 on 32 and 36.
More spokes spread the load across more points and tolerate a high-system-weight hub or a demanding use category better. But that's the judgment of whoever builds the wheel, informed by the ASTM category and the chosen hub's system weight, not a table that turns kilograms into spokes.

No. It was searched across ScienceDirect, Springer, MDPI, Taylor & Francis, IOP, ASME and SAE, plus the manufacturers' documentation, and none turned up. The industry bounds the wheel by system weight, not by spoke count.
By system weight. The maximum permissible static wheel load is 60 % of the hub's maximum system weight, and that maximum runs from 110 kg on the XR 1700 Spline to 140 kg on the FR 1500 Classic and 180 kg on the HU 1900 Spline, for load and motor.
Five use categories, from paved road to downhill and freeride. Each hub is certified within its category, and that category weighs on the wheel choice as much as the kilogram limit does.
By workshop judgment informed by system weight and use category, not by a published formula. The geometric side is documented: the hard limit is under a quarter crosses relative to total spokes, and in the workshop it's used tighter, up to 3 crosses on 24 spokes and up to 4 on 32 and 36.
