Test Your Bike Q

1. Keeping a tire inflated to its proper pressure will

Lower riding resistance

Help protect the rim

Reduce the chance of a flat

Help keep a tire from coming off the rim

All are correct

A tire with low pressure contacts more of the road, leading to increased rolling resistance and greater chance to hit an object that can cause a flat. It also protects from intrusions into the rim caused when hitting an abrupt edge. Over inflating a tire can cause it to come off the rim.

2. When riding a bike at night in Oregon, a bike must have:

A front light

A rear reflector or rear light

A front reflector

Both A and B

Both B and C

In Oregon, when riding a bike at night, it is required to have a front light to illuminate the path ahead and a rear reflector or rear light to make the bike visible from behind. Both A and B are necessary for compliance with the regulations. A front reflector (option C) is not mentioned as a requirement, so it is not necessary for riding a bike at night in Oregon.

3. You know a wheel is not true when:

Some spots on the tire are worn more than others.

The spokes seem loose.

It seems to move from side to side, and/or up and down when rotating.

Cuts in the sidewall appear at even intervals

You catch it lying.

Most wheels can be brought back into true by adjusting the spoke tension. However, this is best left to a skilled wheel builder.

4. You should replace a helmet when

Fashions and styles change.

If the helmet is somewhere between 3 and 5 years old even if it has not been used.

If the helmet has been in a crash.

Both B and C are correct

Only if there is visible damage or the helmet is over ten years old.

Helmets loose their integrity over time due to age and exposure to UV rays. A helmet that has been in a crash may have hidden damage.

5. Barrel adjusters are used on most new bikes to:

Adjust brakes

Adjust gear shifting

Adjust the roller barrel on an internal hub

A and B are correct

B and C are correct

Barrel Adjusters enable the bike owner cable adjustments to compensate for cable stretch. There is no such thing as a roller barrel on possible answer C

Explanation

Barrel Adjusters enable the bike owner cable adjustments to compensate for cable stretch. There is no such thing as a roller barrel on possible answer C

6. A, B, C, Quick Check refers to:

Air, Brakes, Crank, Quick Check

Air, Brakes, Crank, Quick Release

Air, Bike Body,

The correct answer is "Air, Brakes, Crank, Quick Release". This refers to the components that are being checked or inspected in a quick check. The quick release refers to the mechanism used to quickly release or detach a wheel from a bike.

7. Injuries that are the most serious are from:

Head injuries

Car/bike contact

Bike/Pedestrian contact

Wet pavement

Riding too fast

Head injuries are the most serious because they can have severe and long-lasting effects on a person's health and well-being. The head houses the brain, which is responsible for controlling all bodily functions, so any injury to this area can be potentially life-threatening. Head injuries can result in concussions, skull fractures, brain damage, or even death. Therefore, it is crucial to prioritize the prevention and proper treatment of head injuries to minimize their impact on individuals' overall health and quality of life.

8. Toe-in refers to:

Standard brakes and the technique to reduce noise when applied.

Keeping your toes in the straps of toe clips.

Keeping your toes in during a crash.

Holding your toes in the clips while riding hard.

None of the above

By adjusting the brake pads with a toe in reduces squealing.

Explanation

By adjusting the brake pads with a toe in reduces squealing.

9. When repairing a flat, it is essential to:

Wait for the glue to dry before applying the patch.

Apply the patch before the glue dries.

Use your finger to feel inside the tire for any sharp object that may have caused the flat.

Line up the wording on the sidewall with the valve stem.

Bounce the newly inflated wheel on the ground to be sure it is safe to use.

Waiting for the glue to dry before applying the patch is essential for a proper repair. The glue creates a strong bond between the patch and the tire, preventing air leakage. Applying the patch prematurely can result in a weak seal, leading to a recurring flat tire and potential safety hazards on the road.
