GARY FISHER SERVICE INFORMATION
The Cronus uses a special bearing system that has no parts that thread into the frame.
Instead, the bearings are a slip-t into the frame. However, the Campagnolo UltraTorque
system requires you to attach bearing supports (seal seats) to the bottom bracket shell
of the Cronus (Figure 38). This section explains how to do that.
The seal seats might t 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 or bearing press to install
the bearings into the frame. If the bearing t is too tight, make sure the seal seats are
clean and free of debris.
Tools and materials required
To complete the installation, you will also need the Campagnolo instructions, available at:
