Campagnolo UltraTorque
The Speed Concept uses a special bearing system that has no parts that thread into
the frame. Instead, the bearings are a slip-fit into the frame. However, the Campagnolo
UltraTorque system requires you to attach bearing supports (seal seats) to the Speed
Concept bottom bracket shell (Figure 1). This section explains how to do that.
The seal seats might fit into the frame tightly. In this case, you might need to tap the cups
with a soft-faced mallet. However, Do not use a hammer to install the bearings into the
frame. If the bearing fit is too tight, make sure the seal seats are clean and free of debris.
Tools And Materials Required
To complete the installation, you will need the Campagnolo instructions, available at: http://
