Nothing special,..just fun to put it up here
Anodizing, or anodising, is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. Anodizing increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than bare metal. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light. Anodizing is also used to prevent galling of threaded components and to make dielectric films for electrolytic capacitors. Anodic films are most commonly applied to protect aluminium alloys.
Anodization changes the microscopic texture of the surface and can change the crystal structure of the metal near the surface. Coatings are often porous, even when thick, so a sealing process is often needed to achieve corrosion resistance. The process is called "anodizing" because the part to be treated forms the anode electrode of an electrical circuit. Anodized aluminium surfaces, for example, are harder than aluminium but have low to moderate wear resistance that can be improved with increasing thickness or by applying suitable sealing substances. Anodic films are generally much stronger and more adherent than most types of paint and metal plating, making them less likely to crack and peel.
Gold self extracting crank bolts
The cleaning and maintenance of a bike chainset is essential to keeping the best possible shifting performance. In addition, standing dirt and grit on the bottom bracket penetrates seals far faster than if it were given a swift clean at the end of a winters day ride.
This simple level of maintenance can never be as comprehensive as it should be without removing your cranks with a crank extract tool - or a pair of Middleburn self-extract bolts.
With our self-extract bolts all that is required is a 6mm allen key - simple. Anti friction washers ensure minimum effort is required. With the bolt sets available in a range of colours they also provide you with the finishing touch to any bike.
