We all know the problem: First there is an annoying defect, then the wheel (mainly the rear wheel) absolutely refuses to be installed. There actually is a reason for that: The rectangular outer edge of the disc rotor clashes with the rectangular lower edge of the brake pads (as shown in the illustration below). The consequence: You start to fumble, causing you to lose time as well as your head.
Father to the thought was the wish that was repeatedly expressed by racers: To get a disc rotor with chamfer - a roof-shaped tapering of the outer profile of the disc rotor. The aim: To be able to install the wheel as fast and as uncomplicated as possible after having repaired the defect.
Thanks to the rounded 60-degree-chamfer on its outer profile, the new TR!CKSTUFF DÄCHLE-DISC slides into the narrow slot between the two brake pads almost automatically.
140 mm: thickness 1,85 mm, friction ring width: 14,0 mm, weight 89,0 g
160 mm: thickness 1,85 mm, friction ring width: 15,5 mm, weight 111,0 g
180 mm: thickness 2,05 mm, friction ring width: 15,5 mm, weight 153,8 g
203 mm: thickness 2,05 mm, friction ring width: 15,5 mm, weight 191,4 g
Note: Due to the outer 60-degree-chamfer, which does not contribute to the friction ring, the rotor builds up to 1 mm in diameter. The vertical space offer with a few brake calipers may not be sufficient for this reason. Please check beforehand.
