GettinG started and Cautions

The following issues that are important to review before servicing and/or trouble shooting your Chris King hub:

Adjust the preload on the bearings directly after building the wheel

Spoke tension pulling out on the flanges can slightly loosen the preload adjustment on the bearings.Thehub(s)comepre-adjustedfromthefactoryanticipatingbothspoketensionandskewercompression.However,becauseofvariations inwheel-buildingpractices,aminoradjustment should always be performed upon completion of the wheel build. Please see the appropriate “adjustment” section and check the hub before using.

Chris King hubs feature adjustable bearing preload

Thebearingsshouldbekeptinproperadjustmentforoptimumproductperformance.Donotallow the adjustment to become loose, as this may cause a loss of performance that could lead to damage to the hubs.

Rev. 12/12-A 3

Use steel quick releases for maximum rigidity

Our19.5mmaxleisoneofthestiffestavailable.However,performancewillbemaximizedwiththe stiffest possible attachment to the frame or fork. Some Chris King hubs are designed to be usedinconjunctionwithquick-releaseskewers.Itisrecommendedthattheskewerdevelopa minimum of 1100 lb. of clamping force when set. For best performance, use a steel skewer. Titanium skewers are not recommended.

Use only the recommended bolts with our bolt-on hubs

Never use thread locking or mounting compounds

Thread locking compounds are not an acceptably reliable substitution for loose threads or press fitsinhighperformancecomponentry.AllChrisKingcomponentsarepreciselyengineeredtoexactingtolerancestoeliminatetheneedforthreadlockingcompounds.

Use “spidered” cassettes with our aluminum driveshells

The aluminum driveshells of the rear hubs are softer than the steel driveshells, and we recommendtheuseof“spidered”-stylecassettes.Avoidusing“individual”-stylecogsetswiththe aluminum driveshells. Normal notching from individual cog wear should be knocked down with a file.

General cautions

When using any Chris King product in conjunction with other manufacturers’ parts, be sure to follow all manufacturers’ instructions and recommendations.

ThebearingsinyournewChrisKinghubsareofthehighestqualityavailable.However,allbearings will settle and eventually wear with use. Since looseness or “play” in the bearing assembly can develop as a result of wear, Chris King hubs have been designed with an adjustable bearing preload mechanism and any normal play can be eliminated (see the appropriate“...Adjustment”section).

RingDrive™ maintenance

NormalpreventativemaintenanceoftheRingDrive™ is simple and can be performed using basictools.(See“MaintenanceofRingDrive™ & driveshell”, page 6.)

Lubrication

Normal conditions

Innormalridingconditions(0°-43°C),ourRingDrive™ lube is recommended for the bearings andtheRingDrive™. Do not substitute other brands of lube, as they may be too sticky for the helix of the RingDrive™ inhibiting proper engagement.

Service of the bearings

We offer our bearings with either quality steel or ceramic balls, so short term water intrusion should not lead to any substantial damage. Judging when to service the bearings is completely dependent on the riding style and conditions.

1. Chris King sealed bearings have removable snap rings that hold the rubber seals in place. (See figure 9.)

2. Carefully, using a small screwdriver, pick, or penknife, remove the snap ring by inserting tool into split of snap ring. Gently work one end of the snap ring toward bearing center until it is out of its groove. Follow the ring around with the tool until the snap ring is completely dislodged.

3. Lift and remove exposed rubber seal to access theinterior of the bearing.

4. Thoroughly flush the bearing with a light spray lubricant (e.g.WD-40™)andblowdry.Avoidusingcuasticcleanersandcitrusbaseddetergents.

5. Wipedirtandothercontaminantsfromthesealsandsnaprings.Avoidcleaningthesealswith solvent, which could cause deterioration.

Note:somesolvents,syntheticlubricants,andgreaseswithhigh-pressureadditivesmayattackanddamagesealsandothernonmetallicmaterials.Minimizeexposuretothesesubstancesand thoroughly dry hub after cleaning.

6. LayabeadofourRingDrive™ grease, filling the gap between the inner and outer races 1/3 for steel balls or 1/4 for ceramic around the large bearing and 3/4 for steel or 1/3 for ceramic around the small bearing. Then rotate the inner race to work grease throughout the ball area.

7. Replacerubbersealbetweeninnerandouterbearingrace.8. Insert one edge of snap ring into groove of outer bearing race. Press along entire groove

until snap ring is fully seated; a small gap should be visible between both ends of the snap ring.

9. Turn inner race of bearing by hand to test for binding. If bearings do not run smooth, repeat steps1-9.Bindingisoftenaresultofimproperlyseatedsealsand/orsnaprings.

Maintenance of RingDrive™ & driveshell

Inspection

Havingremovedtheaxleanddriveshell(asinstructedabove),theRingDrive™ is accessible through the large sideof the hub shell. Visually inspect the hub’s interior. Under normalconditionsthegreaseshouldlookmoistandmayhavedarkenedslightly.Amodestfilmshouldcoat the moving parts.

Aswiththerestofthehub,theRingDrive™ is designed to operate with some water contamination. Water intrusion can usually be remedied with basic maintenance.

However,ifforeigndebrisisdetectableinthegreaseand/orthegreaselookshardordry,thenacompleteremovalandservicingoftheRingDrive™ is necessary.

Basic maintenance

1. Takeaclean,lintfreeragandwipeanyspentlubricantfrominsidethehubshell.Becarefulnot to drag any dirt or debris from outside the hub into the interior area.

Rev. 12/12-A12

2. Once the interior is clean in appearance, locate the helical splines of the drive ring about an inch inside the large bearing.

3. Usingasofttoothbrush,pullthebristlesacrossthehelixinanoutwarddirection.Workyour way all the way around the inner circumference to remove any small particles that may be in the spline grooves.

4. Oncecompleted,wipetheareadirectlyinfrontofthehelixtoremoveanydebris.Thismethodshouldbeusedtocleanthehelixonthedriveshellaswell.(Ifcompressedairisavailable,blowacrossthehelixesinlinewiththesplinegroovestoremoveanydebris.)

Withtheinteriorwipeddownandthehelixesbrushedclean,afreshapplicationoflubricantshouldbeapplied. TheRingDrive™ is designed to work with our specially formulated low shearRingDrive™ grease. Do not substitute other brands of grease, as they may be too sticky for the helix of the RingDrive™.

5. Lubricate by reopening a gap between the driverings,andlayingabeadofRingDrive™ grease on the teeth between them (see figure 13).

6. Let the rings spring back together .7. Applyafewdropsoflightweight,lowviscosity

oil,withPTFE(e.g.TriFlow™) onto both the helical splines of the movable drive ring and the driveshell (see figure 14).

8. Before reinserting the driveshell into RingDrive™ area of the hub, the helical splines must be clean of any debris.

9. Reinsert the driveshell and complete theassembly as per the instructions below.

RingDrive™ service

In addition to the basic maintenance of the RingDrive™, a complete removal and servicing may benecessary. CompleteservicerequiresourHubService Tool Kit and, as a basic guideline, should be performed at least once a season. Check with your local Chris King dealer for complete service or you may purchase the tool kit at your dealer or directly from Chris King Precision Components.

In a pinch...

IfyouneedtodoaRingDrive™ service and don’t have theHubServiceToolKitorcan’tmakeittoadealer,this method may be used for temporary results:

4.Thehubhasbeendesignedtoallowtheeasyremovaloftheaxleanddriveshell. Thisrequired having tapered bearing contact surfaces. These surfaces can go dry and may then make noise under heavy load.

Solution:CheckandapplyRingDrive™ lube to the driveshell on the bearing contact taper adjacenttotheo-ring(aboutthemiddleoftheoutsideofthedriveshell.)Andontheadjustingcone on the bearing contact taper.

5. The spoke tension on our wheels should be no more than 120Kgf or 1200N. In rare cases, when the wheel has been built at very high tension, the large drive side bearing can become loose and cause creaking.

Solution: Check to see if the bearing will slide out by hand. If this happens, we can supply
