Technology and design

The DCTech BB86-92 - Sram Dub is equipped with Dual Cup technology: two perfectly aligned aluminum cups to eliminate unwanted noise and ensure a rigid and stable connection between the two sides of the frame.

The chrome steel bearings (ABEC5 / P5 – 2RS) ensure high durability and excellent rotational smoothness. The cups are made of 7075 aluminum, an aircraft-grade alloy with a T6 heat treatment for increased wear resistance. The assembly is fully sealed, with axial seals on the bearings and complete protection against the outside elements.

Guarantee

The cups are guaranteed for life. The bearings have a 3-year warranty.
