HANDLEBAR/STEERING: On some models, the handlebar stem may be adjusted for your comfort. The bearing
of the fork in the frame (headset) should rotate easily without play. Adjustment of the headset requires
special tools and should be performed by a bicycle mechanic.
GRIPS: Replace worn grips. Make sure they fit snugly.
BRAKES: The brake levers should be easy to operate without too much play. Too much play will cause
insufficient braking power. The play is properly adjusted if the brake pads meet the rim fully when the brake
lever is pulled one third of the way.
Adjust the brake play by turning the adjusting nuts located at the junction of the brake cable and brake lever.
When you have determined the proper setting, turn the knurled knob at the shaft of the adjusting bolt all the
way down to the brake lever to lock the brake setting in place.
• The right brake lever controls the rear brake. To tighten brakes, turn the adjusting nut clockwise. To loosen
brakes, turn the adjusting nut counterclockwise.
• The left brake lever controls the front brake. To tighten brakes, turn the adjusting nut counterclockwise. Too
loosen, turn the adjusting nut clockwise.
Note: Left and right controls are reversed on bicycles sold in some countries.
Check brake pads regularly for wear and make sure they are properly toed in. Viewed from the side, the brake
pads should be exactly at the height of the rim and slightly toed in the direction of the rotation of the wheel.
The brake pads must display tread. When the tread is worn down, the brake pads must be replaced.
For safety reasons, the brake cables must be replaced every 12 months. This should be included in the annual
maintenance service by a certified bicycle repair and maintenance shop.
ALIGNMENT: If the bicycle does not align properly, immediately bring to a bicycle mechanic or call Yuba’s
Customer Support toll free at 877 889-YUBA.
WHEELS: Make sure the axle nuts on the front wheel and rear wheel are properly closed. Wheels should be
centered in fork or dropouts. Irregular noise from the wheels or the brakes touching the rim indicates that the
wheel requires maintenance. Wheels should be checked regularly for spoke tightness and true alignment.
WHEEL ALIGNMENT: Wheels should rotate smoothly without wobbling from side to side. Check the bearing
play of the hubs by lifting the bicycle and spinning the wheel. The wheel should continue to spin for several
rotations and finally cease spinning. To check the play of the hubs: try to move the rim from side to side
between the fork. During this test, no substantial play should exist. If you detect play or if the wheel is
difficult to turn, the hub bearings must be adjusted. Please contact a bicycle mechanic to have the hub
bearings adjusted.
RIMS: The rims must be smooth and without cracks, breaks, or bulges. Check that they are smooth on the
inside to prevent puncturing the inner tube.
SPOKES: Check spoke tension regularly. Approximately the same tension should be applied to all spokes. If
there is minor loosening of the spokes, you may tighten the nipples, but it is recommended that you take the
bicycle to a bicycle mechanic. If you detect a loose spoke or if the rim has a side play of more than 4mm,
immediately have the wheel trued by a technician. Riding with loose spokes may cause the wheel to fail,
resulting in serious injury or death.
