DT Swiss Aero Aluminum Wheels 2024

Both racing bike wheels share the same aluminum hook rim with a 20 millimeter inner width, which is also available individually in either 28" or 650b, and in three different drillings (24, 28, 32 holes) with the A 510 RIM. Furthermore, aero spokes and internally hidden nipples significantly contribute to their outstanding aerodynamic properties.

For the AR 1600 SPLINE 30, a Ratchet SL freehub with 36 teeth works in the 350 straightpull hubs, while the A 1800 SPLINE 30 manages with a Ratchet LN freehub with 18 teeth in 370 straightpull hubs. Primarily, the two wheel systems differ in their hubs and freehub, though the spokes (DT aero comp II vs. DT aero comp) also show slight variations. The weight difference is manageable with a difference of 33 grams, however, the price difference - depending on the wheel version - is between 100 and 200 Euros.

However, the technical differences should not have a significant impact on the top speed. In all three cases, the lightweight aluminum profile of the rim ensures good aero performance and offers high stability when accelerating, while the rider combats air resistance.

Both the ER 1600 SPLINE 30 and the more affordable E 1800 SPLINE 30 Endurance wheels roll on the newly developed and aerodynamically optimized E 550 RIM rims. These 30 mm high aluminum hook rims with 22 millimeters inside are also available as 28" or 650b variant and in three different drillings (24, 28, 32) individually, and are eager to be used in your individual Aero or Dynamo projects.

As with both road wheelsets, the ER 1600 SPLINE 30 features a Ratchet SL freehub with 36 teeth and 350 straightpull hubs, and the E 1800 SPLINE 30 a Ratchet LN freehub with 18 teeth and 370 straightpull hubs. Primarily, the two system wheels differ in their hubs and the freehub, although the spokes (DT aero comp II vs. DT aero comp) also have slight variations.

Both wheels are also available in the lower rim height of 23 mm (ER 1600 SPLINE 23 / E 1800 SPLINE 23). While the 30 mm high E 550 RIM rim has been aerodynamically optimized to offer you either more range or speed, the 23 mm high aluminum rim is slightly lighter, less susceptible to wind, and cheaper.

For all four wheelsets or rims: The generous inner rim width of 22 millimeters means the aluminum hook rims pair especially well with wide tires (starting from about 28 mm), improve the ride feel at low tire pressure, reduce rolling resistance, and thereby increase versatility in terms of comfort and traction.
