YBEKI Bike Disc Brake Rotor 140mm 160mm 180mm 203mm Heat Dissipation Disc Brake Rotor with 6 Bolts for Road Bike Mountain Bike MTB BMX Stainless Steel Bicycle Rotor (red, 180mm)

Despite appearances these YBEKI discs are not a steel/aluminium/steel lamination like similar looking Shimano discs. Instead they are a steel floating disc of mediocre quality with an aluminium insert wedged into each spoke of the disc. The genuine laminated discs have an aluminium core that conducts heat straight to the aluminium fins as a one piece construction. These inserts do not make good thermal contact with the steel and therefore do not significantly improve heat dissipation. They are essentially cosmetic to look the part.If you need floating discs there are ones of similar quality at half the price, alternatively there are single piece discs for 1/4 the price. Either option are significantly better value than this brake disc.

Légèrement voilée sinon il chauffe beaucoup moins que les Shimano peut être a cause de l’emballage j’en ai commandé un autre pour l’arrière et s’il est voilé je le retourne

FRENANO MOLTO BENE ED ANNO UN BEL ASPETTO

Mal was Anderes als das Einheits-Silber und noch dazu gute Bremswirkung, fast kein Ruckeln trotz der Langlöcher

Lleva pocos kilometros realizados y de momento en una pinza de freno shimano xt, funciona correctamente.

Very good and nice product!
