DT Swiss RR 411 700C 21 Symmetric RB VI Tubeless Road Rim 700C 28H Black

The most advanced alloy existing for rims meets the most advanced rim profile to form the RR 411 rim. From the moment the alloy is melted all the way to the secret surface treatment, this rim is all about getting the absolute best out of the great, shiny metal that is aluminum. Very light, very strong, very classy is the result. The RR 411 is available with a symmetric as well as an asymmetric rim profile.

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.
