Trickstuff Exzentriker Bottom Bracket
Unrivalled: the eccentric bottom bracket from Trickstuff
Trickstuff would not be Trickstuff without dreamy parts like the eccentric bottom bracket. This is the first and only eccentric bottom bracket that can be mounted in normal BSA bottom bracket shells and can accommodate any conventional 24 mm bottom bracket shaft (e.g. Shimano Hollowtech II and many others). It is used for infinitely variable adjustment of the chain tension on single-speeds or hub gears (e.g. Rohloff) and makes chain tensioners or adjustable dropouts unnecessary. The eccentric bottom bracket cradles the bottom bracket shaft between two soft-turning special ball bearings, which are distinguished from conventional bearings by their stainless steel and special grease, offering an almost infinitely long service life. The eccentric is also patent-protected, and, naturally, dreamed and conceived in the Black Forest!

Note: With conventional triple mountain bike cranks, the bases for mounting the small chainring collide with the outer contour of the Exzentriker housing.The remedy for this is to use single cranks (e.g. Shimano Alfine or similar), dual racing bike cranks or current dual or single MTB race cranks or file off pedestals.
