Press Extensions

Sometimes it's helpful to have a bit more space between the press drift and the T-bar handles, to give more clearance from obstacles that might otherwise make tightening the press awkward.  This might be the case when pressing frame pivots near to the bottom bracket shell, or a curved chainstay.  Other times it's necessary to press a bearing deep into a part like a freehub.

Our 'press extensions' come as a pair of tubes 20mm long.  They can be used in any combination with any of our presses, including our frame presses, bottom bracket presses and headset cup presses.  They can even be used with our optional thrust bearings!   

Note that a pair of these extension tubes are included with all of our T-bar frame and bottom bracket presses.

Our tools can be selected either by the bearing's dimensions or by the bearing's standard reference code.

Standard references take the form of a three to five digit number, such as 688, or 6902 for example.  These codes are often provided in the bike's user manuals, or moulded onto the bearing's seal. You might see something like 6902-2RS on the seal. The first digits are the standard reference.  The second part (2RS in this case) refers to the seal type and doesn't matter for tool selection.

While the letter & numbers after the baring ref usually refer to the type of seal, you should keep an eye out for the suffix 'E', for example 698-E.  This denotes that the inner race of the bearing is extended, which will affect puller and press selection. 

Alternatively, tools can be selected by their inside (ID) and outside (OD) diameters and width (W). 

Note that each tool is specific to one bearing size and can’t be used on bearings with different dimensions.
