Auswahl und Montage eines Patronenlagers: Unterschied zwischen den Versionen

 

These are common with newer cranks, and thread into the frame same as other bottom brackets, only the bearings are outside the ends of the bottom bracket shell, making it possible to use a large-diameter hollow axle for greater stiffness and lighter weight.

 

Park Tool has good instructions online for this complicated and finicky bottom-bracket installation. The alignment of the threads is critical, as the bearings at the right and left sides are not aligned to each other by a cartridge.

 

Phil Wood sells outboard-bearing assemblies that fit every bottom-bracket threading and Klein press-in bottom brackets, making it possible to retrofit outboard-bearing cranks onto an older frame. Different manufacturers use different spline patterns to fit the crank to the axle. Phil Wood bottom brackets work with Shimano cranks and others that have the same dimensions, though not all that use outboard bearings and in particular, not Campagnolo. Though the Phil Wood assembly is sold in the Raleigh 26 TPI threading, it probably will not work with the long (76mm) bottom bracket shell of the Raleigh Twenty, Tourist and Chopper.
