Precautions: Important

• Before beginning any exercise program, consult your physician.

• Keep your eyes on the road. D o n

We recommend familiarizing yourself with computer functions while stationary.

• The computer, receiver, and hub are water resistant, n ott water proof. Avoid sustained water contact and do not deliberately place the PowerTap or its components in water or under highpressure sprays. Therefore caution should be used when riding in rain. Following such rides, special precautions should be taken including removing the PowerTap plastic twist cap and allowing the hub to air dry.

• Wash off dirt with a cloth soaked in a weak mixture of neutral detergent and water and wipe excess water off with a dry cloth Avoid spraying the unit directly with solvent mixture. Do not use thinner or other solvents to clean parts as they may dissolve the plastic console casings.

• If you are not familiar with bike maintenance please contact a professional bicycle mechanic before servicing. The power measuring components of the PowerTap are highly complex and should only be serviced by Saris Cycling Group.

• The plastic cover on the hub should be removed only when replacing batteries or when allowing the unit to dry after submersion in water. Repeated disassembly may compromise the effectiveness of the O-ring seals. O-rings should be inspected and replaced if necessary when ever the battery cover is removed. Use a light coating of grease when reinstalling the battery cap on the O-rings.

• During the course of repair d o n ott remove the torque tube. There are no serviceable parts inside. Special tools are required for reassembly and calibration. If problems are suspected contact Saris Cycling Group directly at 800-783-7257 (001 608 274 6550).

5

Precautions: Important, cont.

• The PowerTap wheel does not include a quick release skewer. CycleOps recommends using a steel skewer.

• B otth ess o e P errT ap ou e b uiilltt u g a x ssp ok e lla ciin g p design of the PowerTap, torque is transmitted through the hub to the non-drive side. For additional questions please consult WHEEL BUILDING .

• Failure to adhere to these precautions may cause premature failure or incorrect operation of the unit and may void the warranty. Please register your PowerTap at www.cycleops.com.

System Overview

T HE WE R T P S YS M

The PowerTap system includes a power-measuring hub which measures torque and wheel speed. This information is transmitted to a computer mounted on the handlebar or stem. Heart rate data is transferred via A coded telemetry signal from the chest strap monitor. The data is then integrated to display current, average, and maximum biometric information.

PR EP RIIN G F OR TA LL TIIO

The PowerTap SL2.4 hub comes either alone or in a pre-built wheel. If purchased alone, the hub must be built into a complete wheel prior to use. Other items necessary for installation and not provided include a cassette, spoke protector, reflectors, skewer, rim strip, tire, and tube (clincher rim) or glue and tubular tire (tubular rim). See TABLE 1 to verify package contents.

The PowerTap SL2.4 hub is compatible with Shimano 8, 9, and 10 speed systems or Campagnolo

8, 9, and 10 speed systems. Freehub bodies may be interchanged. Reference FREEHUB

REPLACEMENT for further instructions.

The PowerTap is available in 130mm and 135mm axle lengths. 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. Contact your dealer or Saris Cycling Group to address any special compatibility concerns.

This setup allows the CPU to learn a new device or sensor such as the hub, heart rate strap and optional cadence sensor. NOTE: This process only needs to be used if a new sensor or hub is being used in conjunction with your CPU or vice versa and if batteries are changed in the hub or chest strap. There are 2 Learn sequences, 1 and 2. Learn 1 is used when you have switched sensors or the CPU and there are no other like bikes with PowerTap SL2.4 within a 30’ radius. Learn 2 is used if there are other devices in the area but requires you to remove and reinsert the battery before activating the Learn 2 sequence.

The power measuring components inside the PowerTap SL2.4 are highly complex and should only by serviced by Saris Cycling Group. The bearings are sealed type 6901RS 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

SL2.4 uses a modern 4 bearing design and does not require any tensioning adjustment.

F RE HU

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.

The PowerTap SL2.4 has batteries in the hub and computer. Computer batteries typically need to be changed every 400 hours of use. The computer will also say “low bat” when the computer 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. Remove the battery cover on the back of the computer (use a cone wrench to remove the battery cover), exchange the battery, and replace the cover as shown below

(FIGURE 29).

Normal battery life in the hub is 400 hours of actual ride time. Use #357 or EPX76 Silver Oxide type batteries and always replace batteries in pairs. Alkaline type batteries give shorter life and poorer performance. NOTE: After replacing batteries in the hub you need to Learn the device codes.

See computer setup 5.

- 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.

- Remove the battery pack. A small screw driver can be used back and forth between the to ends to start to lift it out.

- Pop the battery out by bending the plastic retaining tap back and pushing the batter up from the bottom.

- Check that the electrical connector tab from the inside of the hub is perpendicular to the bottom of the battery pocket. If the tab gets bent, gently press it back to perpendicular with a non-sharp tool.

-Slide the battery pack back into position along the center core. As the battery is engaged a small increase of resistance to installation should be felt as the electrical connections are made.

- Thread the cap all the way back on.

- Replacement O-rings and battery packs are available from Saris Cycling Group.
