Maintenance & Specifications
The following information will help you keep your PowerTap running properly. If you are not
familiar with hub maintenance please consult a professional bicycle mechanic before servic-
ing.
During the course of any repair do not remove the torque tube. There are no user serv-
iceable parts inside. Special tools are required for reassembly and calibration. If prob-
lems are suspected contact Saris Cycling Group.
BEARINGS
The power measuring components inside the PowerTap are highly complex and should only
by serviced by Saris Cycling Group. The bearings are sealed and do not require replacement.
Field replacement can cause permanent damage to the power measuring electronics and
result in compromised sealing and performance. If bearing problems are suspected
please contact Saris Cycling Group at 1-800-783-7257 for a return authorization. The
PowerTap uses a modern 4 bearing design and does not require any tensioning adjustment.
Ceramic Bearings are used in the SLC+ model. These are a hybrid construction of higher quali-
ty steel inner and outer race, ceramic balls and a plastic cage. The ceramic balls are lighter,
harder and smoother than traditional bearings. In addition a special low friction seal is used.
FREEHUB
The grease in the freehub pawls should be replaced if it becomes contaminated with water.
Replace the seal at the same time, contact Saris Cycling Group for replacement parts. Saris
Cycling Group recommends the following types of grease to ensure proper functioning:
