INTRODUCTION & PRECAUTIONS Thank you for your purchase of the CycleOps PowerTapTM . Power is the ultimate measure of performance. No other equipment will give you greater return on your investment. For more information regarding training with power, please go to our Web site at www.cycleops.com PRECAUTIONS: IMPORTANT 1. Before beginning any training program, always check with your physician. 2. Keep your eyes on the road. Do not become overly engaged with the PowerTap display.
SYSTEM OVERVIEW The PowerTap System The PowerTap system includes a power-measuring hub which measures torque and wheel speed. This information is then transmitted via digital radio frequency to a receiver mounted on the seat stay. The data is wired to the PowerTap computer mounted on the handlebar. The computer receives the signal from the heart rate monitor chest strap to provide heart rate information. All of this information is then processed for display on the computer.
SYSTEM OVERVIEW Compatibility The PowerTap SL hub is compatible with Shimano 8, 9, and 10 speed systems or Campagnolo 8, 9, and 10 speed. Free hub bodies may be interchanged. See page 24 for instructions. Only insert the correctly spaced PowerTap hub into your frame. For example, only use a 130mm-spaced hub in a 130mm road frame. Do not force the hub into any frame. Doing so may cause failure of the frame, hub, or both, and will void the warranty.
SYSTEM INSTALLATION 1. Insert Wheel Into Frame Insert the complete built PowerTap wheel into the frame. Make sure the axle is correctly positioned in the dropouts and secure wheel in place with a steel skewer. 2. Attach Receiver To Seat Stay Place foam tape between the receiver and frame for a slip-free fit. If necessary, rotate receiver to within 5 degrees of parallel with the hub battery cover before tightening cable ties. Mount receiver a maximum of 3 inches from the axle.

MAINTENANCE & SPECIFICATIONS The PowerTap SL uses a completely new free hub, axle and bearing design that should provide many miles of trouble free training and racing. The following information will help you keep your PowerTap SL running properly. If you are not familiar with hub maintenance please consult a professional bicycle mechanic before servicing. During the course of any repair DO NOT remove the torque tube. There are no user serviceable parts inside.
MAINTENANCE & SPECIFICATIONS 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: -Kluber Isoflex NB52 o -Dupont Krytox GPL226 Warning: Failure to use the proper grease on the freehub pawls could result in engagement problems.
MAINTENANCE & SPECIFICATIONS Computer Batteries The PowerTap SL has batteries in the hub and computer. Computer batteries typically need to be changed every 1,000 km or approximately every 100 hours of use. The cpu will also say "low bat" when the cpu battery needs to be changed. This message is displayed after a "clr" is performed. To replace computer battery (Type CR2032), remove the computer from the mount.
HUB BATTERIES Normal battery life in the hub is 250 to 300 hours of actual ride time. Use #357 Silver Oxide type batteries and always replace batteries in pairs. Alkaline type batteries give shorter life and poorer performance. Battery replacement -Unscrew the plastic battery cover. Use a spanner wrench or bench vise opened wide to get it started if stuck. There are O-ring seals that can cause the cover to resist the start of motion. The threading is normal right hand.

Devices that use serial ports are: Digital camera PDA (Personal Digital Assistants like Palm Pilot) Mouse Modem Check the computer BIOS that the serial ports are turned on and in a normal state. The “plug and play” mode should work for most computer setups. Sometimes this does not work and the default manual settings should be used.

The PRO will respond with XX.XX PRO XX/YY/ZZ XXXX” This is the firmware version and serial number information. Serial Port Trouble Shooting ·Check to make sure your COM port setting (see: Options > Application Setup) corresponds with the physical COM port on your PC. ·Check to make sure the COM port is not configured for another application.
TROUBLESHOOTING 1. Remove the CPU from the Link download cradle immediately after the download is completed. Leaving the CPU on the download cradle will contribute to excessive battery drain. Important: Just removing the CPU from the download cradle and allowing it to go into the blank LCD sleep mode does not return it to its normal power-conserving mode and you must complete the next two steps. 2. Place the CPU into the bike receiver shoe and wake it up by pressing either button. 3.
TROUBLESHOOTING ·Is the link on the same Com port that the software is set for? (The default is Com 1) If not, set to the same Com port. ·Is there PDA hot sync software running? If there is, disable hot sync software. ·Are other programs or applications running? ·Does it work on another computer? If the Link software installs and you can successfully download data on another computer you will need to determine what is interfering by walking through all of the above items.
