Dynacraft SINGLE SPEED Owner's Manual page 85

The following are examples of the type of service you should perform yourself. All other service, maintenance
and repair should be performed in a properly equipped facility by a qualified bicycle mechanic using the correct
tools and procedures specified by the manufacturer.
1. Break-in Period: Your bike will last longer and work better if you break it in before riding it hard. Control
cables and wheel spokes may stretch or "seat" when a new bike is first used and may require readjustment
by your local bicycle repair shop. Your Pre Ride Safety Check (pages 16-17) will help you identify other things
that need readjustment.
2. Before every ride: Pre Ride Safety Checks (see pages 16-17).
3. After every long or hard ride; if the bike has been exposed to water or grit; or at least every 100 miles: Clean
the bike and lightly lubricate the chain's rollers with a good quality bicycle chain lubricant. Wipe off excess
lubricant with a lint free cloth. Lubrication is a function of climate. Talk to your dealer about the best lubricants
and the recommended lubrication frequency for your area. Avoid contaminating the rims with lubricant!
4. After every long or hard ride or after every 10 to 20 hours of riding:
• Squeeze the front brake and rock the bike forward and back. Everything feel solid? If you feel a clunk with
each forward or backward movement of the bike, you probably have a loose headset. Have your dealer
check it.
• Lift the front wheel off the ground and swing it from side to side. Feel smooth? If you feel any binding or
roughness in the steering, you may have a tight headset. Have your dealer check it.
• Grab one pedal and rock it toward and away from the centerline of the bike; then do the same with the
other pedal. Anything feel loose? If so, have your dealer check it.
• Take a look at the brake pads. Starting to look worn or not hitting the wheel rim squarely? Time to have the
dealer adjust or replace them.
• Carefully check the control cables and cable housings. Look if any rust, kinks, or fraying has occurred and
if so, have your dealer replace them.
• Squeeze each adjoining pair of spokes on either side of each wheel between your thumb and index finger.
Do they all feel the same? If any feel loose, have your dealer check the wheel for tension and trueness.
• Check the tires for excess wear, cuts or bruises. Have your dealer replace them if necessary.
• Check the wheel rims for excess wear, dings or dents and scratches. Consult your dealer if you see any rim
damage.
• Check to make sure that all parts and accessories are still secure, and tighten any which are not, including
but not limited to pedals, crank arms, chains, seatpost, and handlebars.
• Check the frame, particularly in the area around all tube joints; the handlebars; the stem; and the seatpost
for any deep scratches, cranks or discoloration. These can be signs of stress-caused fatigue and indicate
that a part is at the end of it's useful life and needs to be replaced.
