CHRIS KING R45D Gen 4 Hubset

QUICK START

1. CHECK THE BIKE
   Check the frame and fork dropouts to ensure that they are parallel to each other. If in doubt, use an appropriate tool made by a reputable bicycle tool manufacturer. Non-parallel dropouts may damage or compromise the performance of your hub.
2. INSTALL ROTORS
   1. Please follow the rotor manufacturer’s instructions and specifications for installation.
   2. CENTER LOCK LOCKRING NOTE: To allow for engineering clearance please use lockrings with a large inner hole diameter.
3. INSTALL CASSETTE
   1. We recommend cassettes that use grouped cogs vs individual cogs, when possible.
   2. Please follow the cassette manufacturer’s instructions and specifications for installation.
4. CHECK PRELOAD
   1. Chris King hubs and wheels come with the preload adjusted from the factory. Before riding check to ensure Preload works correctly in your bicycle frame.
   2. Mount the wheel securely in the bike and hold the rim between the thumb and index finger checking for lateral motion.
   3. If you experience looseness, lateral play or binding adjust the bearing preload per instruction in the Maintenance Section.

BREAK IN PERIOD

• Once you start riding your new hub, some settling may occur. During the first 60 hours of use, check for lateral play or binding by grabbing the rim near the tire and moving back and forth. Readjust the clamp if necessary.
• During the first 60 hours of use, above-average amounts of drag may be noticed. This is normal as the seals break in, and will soon diminish.

REAR HUB:
Normal preventative maintenance of the RingDrive is simple and can be performed using basic tools. In many cases, a minor cleaning and reapplication of lubricant is all that may be necessary. Judging when to perform this basic maintenance is determined by riding style and conditions. As a guideline, your hubs should be maintained every 12 months in normal and dry conditions and every 6 months in wet or muddy conditions.

During your REAR HUB QUICK SERVICE, check the bearings to ensure they are running freely and smoothly. If NOT proceed with a Professional Mechanic Service. this includes the removal of the RingDrive engagement mechanism and requires the use of our Hub Service Tool. See any authorized Chris King dealer for Professional Mechanic Service or you may purchase a Hub Service Tool Kit from your dealer or directly from Chris King Precision Components. Chris King Precision Components provides overhaul services at reasonable rates.

30 MONTHS or 20k MILES
FRONT & REAR HUB: Perform a Professional Mechanic Service using the Chris King Universal Hub Tool.

WET/MUDDY CONDITIONS
Riding in wet or muddy or conditions necessitates more frequent service. Often this is as simple as removing the Axle and Driveshell from the hub and removing any moisture from inside the hub shell. This should not replace periodic complete disassembly and maintenance, especially in extreme or prolonged wet conditions. Since it is nearly impossible to seal a hub from water and still have it spin freely, we have designed our hubs to be able to operate normally with some water intrusion. High-pressure spray washing, transporting or riding the bicycle in the rain, or submersion in water while riding can all lead to lubricant contamination by water. Be aware of these situations and service more frequently when they occur.

FRONT HUB

PRELOAD ADJUSTMENT

SPECIFICATIONS

GENERAL 

WHEEL BUILD INFORMATION
Chris King hubs are designed to work with 13, 14, or 15-gauge spokes. Disc brake wheels must be laced using at least a 2 cross-lacing pattern. As the torque generated by driving the cassette requires crossed spokes, so does the additional torque on the non-drive side flange generated by the braking action. Radial lacing your hubs is considered outside of the intended use and will void your warranty. We will not be responsible for damaged or destroyed hubs, any consequential damages, or any resulting labor costs due to radial lacing your hub.

Proper wheel-building techniques are essential in creating a strong wheel. Wheel building is a skill that requires proper training and specialized tools and should be done by a trained professional. The spoke tension on each side of the wheel should be as uniform as possible. Tension should not exceed 120kgf (1200N). The hub(s) come pre-adjusted from the factory, however, a minor adjustment should be performed upon completion of the wheel build.

• FRONT HUB SPECS FOR WHEEL BUILDING:
  • Axle Width: 100mm
  • Flange Diameter DS & NDS: 57.4mm
  • Center to Flange DS: 30 .6mm
  • Center to Flange NDS: 22 .2mm
• REAR HUB SPECS FOR WHEEL BUILDING:
  • Axle Width: 142mm
  • Flange Diameter DS & NDS: 57.4mm
  • Center to Flange DS: 18.7mm
  • Center to Flange NDS: 33 .0mm
