Want to make the challenge of a long, extended ride more accessible? Upgrade your bike with the aero-optimized E 550 rim. This ultimate long distance rim gives you the stability and comfort to ride further with confidence. The 22 mm inner rim is optimized for 28 mm wide tires, giving you comfort and lower rolling resistance when inflated at lower pressures. With the E 550, you have no excuses not to extend your ride.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.Pro Lock:- Pro Lock is a thread lock function which prevents the spoke-nipple connection from loosening, allowing for extremely durable wheel builds.
