This is ReveD Aluminium Competition 5.5mm Large Diameter Large M4 Nut 2 pcs Black. Introducing our large-diameter ultra-lightweight M4 serrated nut optimized for the rear! Our original RD-013 nuts have been well received as being ideal for the front, these are our new rear specific competition M4 nuts. Increasing the diameter of the flanged part helps to control some of the lateral forces applied to the wheel mounting point, helping to improve side bite! Hexagonal dimensions are still 5.5mm which is the same as RD-013 in order to use the same box wrench for both front and rear. They can be used with RêveD competition wheels or the other brand wheels helping you achieve the best traction performance! Try the ultra-lightweight competition M4 nut, which produces great effects even with small parts.
