DT Swiss is doing business right now
"Spline" (an abbreviation for "Straight Pull Line") is DT Swiss' code word for spokes lying straight in the hub flange. As this concept eliminates the spoke bend, the entire wheel should be even stiffer and execute braking, drive and steering commands more directly. The manufacturer promises that the "spline" design makes it possible to align the spokes with mathematical precision and thus minimize the amount of material required in favour of the weight/stability ratio.
Now "Spline" is not only available with the system wheels from Biel, but also in Do It Yourself mode. Some hubs are already available from Intercycle in the straight pull design, such as the "350 Straightpull" hub. One spoke type with a straight pull up to the spoke head is currently available, with the competition spoke being given the additional designation "SP".
The DT Swiss spoke calculator has also been adapted to the new conditions and offers new options: To determine the appropriate spoke length, you now have to choose between "Classic" and "Spline", i.e. between wheel components for straight spokes or spokes bent at the head.
