Break-In

Once your new hub is placed in service, some settling may occur. Check adjustment by clamping

wheel into frame with a quick-release skewer. Ride for 5-10 minutes, check for play or binding,

and readjust clamp or cone if necessar y. Recheck after the first 1-5 hours of riding. Check cas-

sette lock ring on rear hubs after the first 20 hours of use, and tighten if necessar y. Continue

monitoring for the first 60 hours of use.

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. If this causes chain sag in the rear while back-

pedaling, increase the B-tension (cage tension) on the rear derailleur.

A small amount of grease or oil may seep at the bearing seals during the break-in period.

Notes on RingDrive

™

Normal preventative maintenance of the R ingDrive is simple and can be per formed using

basic tools (see " The RingDrive", pg. 8). In many cases, a minor cleaning and reapplication

of lubricant is all that may be necessar y. Judging when to per form this basic maintenance

is determined by riding style and conditions. As a beginning guideline, your hubs should

If foreign debris is detectable in the grease and/or the grease looks hard or dry, a complete
