Dt Swiss Rr 511 700c 32 Rb Vi Tubeless Road Bike Rim. Build your ultimate wheelset with the DT SWISS RR 511 rim. Engineered for super-stiff and reliable performance, its 32mm semi-aero profile cuts through the air while remaining surprisingly light, thanks to an advanced alloy construction. The robust, welded design and tubeless-ready compatibility make it a versatile choice for everything from fast road rides to demanding gravel and cyclo-cross courses. This 700C rim brake model is the perfect starting point for a durable, high-performance wheel build that won´t let you down. Anyone wanting to build a reliable super-stiff wheel is starting in the right place with the RR 511. Thanks to a state-of-the-art alloy and surface treatment, this extremely robust 32 mm high semi-aero rim is lighter than you would think. And those thinking of using it on Gravel or Cyclo Cross courses can easily install tubeless tires. Features:System weight:- The system weight is composed of the weight of the rider and his equipment, plus the bike with luggage.Welded:- Welded refers to a method used in making rims. In this case, the profile ends of the rim are connected by welding. This precise, stable and lightweight connection is used on all high-quality aluminum rims. This manufacturing process is the most expensive due to the effort involved, but it offers the most reliable connection. 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.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. 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. 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.Pro Lock:- Pro Lock is a thread lock function which prevents the spoke-nipple connection from loosening, allowing for extremely durable wheel builds.
