Reaching new top speeds is now available to all. The DT Swiss A 1800 Spline 30 brings aero-optimized performance to everyday riders — built around DT Swiss's first aero-optimized alloy rim, paired with hidden nipples and DT aero comp wide straightpull spokes that compound the aerodynamic advantage at every turn. Whether you're chasing local KOMs or just want to go faster with less effort, the A 1800 Spline delivers wind-tunnel engineering at an accessible price point.

Rim
An all-new aerodynamic alloy rim shape at 30mm height with a 20mm inner width. Hidden nipples keep the profile clean and aero, while the hooked tubeless-compatible bead seat means you can run tubeless straight out of the box — tape and valves are pre-installed.

Spokes
DT aero comp wide straightpull spokes feature a redesigned aero profile, making them faster than their predecessor and pushing the aerodynamic advantage beyond just the rim.

Hub
The DT Swiss 370 hub now features the Ratchet LN 18 system. Simultaneous tooth engagement delivers reliable, instant power transfer on every acceleration — backed by the signature DT Swiss freewheeling sound that rewards you at the end of every sprint.

Freehub Body
The Ratchet LN system engages every tooth simultaneously, giving you the reliability and snap you need when it matters most. Available in HG and XDR freehub configurations.
