D.I.D. PRO-STREET X-Ring Chain Set
D.I.D. You get the expertise of a worldwide original equipment manufacturer. Extremely strong, extremely durable and extremely effective. High efficiency as well as soft andfast reaction to load changes of the D.I.D. chains are the result of years of further development in racing, state-of-the-art production methods and highest material quality. The currently bestD.I.D chain in terms of deformation and elongation.
The secret behind the amazing performance of the chains is D.I.D's exclusive pin hardening process. This process forms a hardening layer on the surface of the pins.extremely hard layer, but keeps the bolt core softer. These chains are particularly resistant to contact with hard foreign bodies, while they simply absorb shocks. For this they arestill well protected against rust.
The specially shaped D.I.D-X-ring seals decisively change the friction surface of the tabs. At the same time the doubling of theSealing points from 2 to 4 a much higher security against lubricant loss and a perfect protection against contamination.
ESJOT is a producer in the bicycle industry, with whichGermany's most extensive stock of sprockets and pinions. The steels used meet the highest demands and thus satisfy OEM quality. High tensile strength of the materialguarantee a long service life. The aluminium sprockets are made of aluminium 7075 version T6. This hardened material guarantees, in connection with complete milling on the most modernCNC machines, for highest quality. Of course all ESJOT sprockets are anodised.
The innovative production process Diamond-Cut for the toothing of sprockets withcompared to the conventional milled sprocket a significantly higher quality standard is achieved. Precision tools provide you with an optimized cutting pattern. At the same time theMaterial in the tooth flank area highly hardened, so that in many cases an additional hardening process is not necessary. Only the highest quality German steels are used in order to achieve a consistently highto guarantee quality.
