Dt Swiss H 1900 Spline 30 27.5´´ Cl Disc Tubeless Mtb Rear Wheel. Conquer any trail with the DT SWISS H 1900 Spline 30 27.5" CL Disc Tubeless rear wheel. Built for durability and performance, it features a robust sleeve-jointed aluminum rim with a 30mm inner width for excellent tire support and tubeless compatibility. The 12mm thru-axle and 148mm Boost spacing provide exceptional stiffness and secure mounting. Ready for your Shimano 12-speed setup with a reliable Ratchet LN freehub system and Center Lock brake interface, this wheel is engineered for demanding MTB use, including e-bikes. Features: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.Hooked / Crotchet tubeless TC:- Hooked or crotchet refers to the shape of the rim flange. In this variant, the rim flange has a so-called hook. This supports the fixation of the tire bead and ensures safe function, also in high pressure use cases (>5 bar tire pressure). Tubeless refers to the ability of the rim to be used without a tube, but a tube set up is also possible.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 Inner Width:- DT Swiss offers MTB rims with inner rim widths of 20 - 76 mm. The right combination of tire width and rim width leads to ideal tire support. Better tire support reduces the risk of ´´burping´´ and therefore allows the tire pressure to be reduced. On the other hand, wider rims and wider tires also increase the weight of the wheels.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.Boost:- Boost refers to wider axle dimensions. Frame and fork manufacturers use this to build a stiffer bike overall. A flatter spoke angle on the wheel can be created by increasing the flange distance, which improves the symmetry and increases the stiffness, especially on large wheels.Brake :- 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. Center Lock:- Center Lock refers to a system for brake discs that was developed by Shimano. The brake disc is mounted on the hub by means of an external spline and screwing on a lock ring. The advantage of the Center Lock system is that the brake discs are centered and mounting requires only screwing down a single lock ring.Shimano 12SP Steel (SS12):- Steel freehub body for Shimano 12-speed cassettes. 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. Pro Lock:- Pro Lock is a thread lock function which prevents the spoke-nipple connection from loosening, allowing for extremely durable wheel builds.
