The first and only worldwide Exzentertretlager, which can be mounted in normal BSA bottom bracket shell and absorbs any conventional 24-mm bottom bracket (eg Shimano Hollowtech II and many others). It is used for continuous adjustment of the chain tension at Singlespeedern or hub gear bikes (eg Rohloff) and makes the chain tensioner or adjustable dropouts superfluous.
The Eccentrics embeds the bottom bracket in two soft rotating Phil-Wood-ball bearings, which compared to conventional bearings are characterized by their rust freedom and their special grease and offer an almost infinitely long bearing life.
Caution: The Eccentrics only fits with cranks that have no projecting images for a small chainring and have a continuous 24mm bottom bracket.
Material: Steel (Einschaubhülsen), aluminum 7075 T6 (eccentric) Width: (use spacers) 68mm, 73mm (without spacers) Color: black or silver
Installation: screwing the bearing shells into the frame a special tool is required.
