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, one 15mm long and one 25mm 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!
Ourtools can be selected either by the bearing size or by the bearing's standard reference code.
Standard references take the form of a three or four digit number, such as 688, or 6902 for example. These codes are often 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.
Alternatively, tools can be selected by their inside (ID) and outside (OD) diameters and width.
Note that each tool is specific to one bearing size and can’t be used on bearings with different dimensions.
