Everything about our A 1800 SPLINE 30 is designed to make the discovery of a new world of speed accessible and enjoyable. Based on our first aero-optimized alloy rim, it marks the democratization of our Aero category. In addition to the rim, hidden nipples and aero spokes enhance the aero advantage. So what are you waiting for? Get them on your bike and chase those local KOMs with speed and the wind as your ally. A 1800 SPLINE WTS: The A 1800 SPLINE wheels are now available as an aero-optimized wheel tire system (WTS), mounted with the new AERO 111 tire in 26 mm width in the front and a Continental GP 5000 STR in 28 mm width in the rear.Sleeve joint:- Sleeve joint refers to a method used in making rims. In this case, the two rim ends are pressed together via a molded aluminum part. This gives these rims a high degree of stability.Rim Diameter:- The 700c (622 mm / 29 inches) is the most common wheel size for road racing. The 650b (584 mm / 27.5 inches) wheel size is used in specific areas. Each wheel size offers unique advantages for different kinds of riding.Rim height:- In cycling, rim height significantly impacts the aerodynamics, agility and weight of the wheel. The general principle is the higher the profile of the rim, the greater the aerodynamic advantage, the lower the profile of the rim, the greater the response and better the handling when cornering and changing speed. Thru-axle:- Thru-axle refers to a wheel mounting system. RWS technology from DT Swiss allows quick, precise mounting simply by turning an easily adjustable lever. Thru-axle systems guarantee a rigid and secure connection between the wheel and the frame. Thru-axles must be compatible with the frame and fork because the built-in-width, diameter and thread of the axle vary and are defined by the frame and fork manufacturer.Brake Interface:- The advantage of the Center Lock system is that the disc brake attachment is made with one single lock ring, which facilitates assembly. On the other hand, an advantage of the IS-System (6 Bolt) is that in the event of a necessary repair on the trail, no special tool is needed for disassembly. SRAM XDR RD. (AXDR):- Aluminum freehub body for SRAM 12-speed road cassettes with XDR intake. Visit the brand website for more details about the compatibility of the freehub bodies.Straightpull:- Straightpull refers to spokes without the classic J-bend head. The lack of a bend in the head eliminates one of the spoke's weak points, making it very robust and stable.
