Hi,

My Grandson got a new bike, and thought I'd ask you experts some
questions that have come up. I have to admit I know nothing
about "bike mechanics," and would be most grateful for the help.

a. Regarding the cam-lock that holds the wheel to the fork:

Clever gadget.


That's known as a Quick Release axle. Make sure you know how to operate
it. It's very common for people to use it wrong, think it's tight
enough, and crash because of it. See
http://www.bicyclinglife.com/HowTo/UseAQuickRelease.htm


But, the only way it seems to take the wheel completely off
is to deflate it. Otherwise, we can't get it passed the brake pads.

Are the brake pads, in their relaxed position, supposed to be wide
enough to allow the tire to be passed thru them, easily ?
Or,...?


What type of brake are you dealing with? If this type:

you can open the brakes easily by unhooking the noodle. See the fourth
photo down, not counting Sheldon's smiling face.

If it's a different type of brake, it may have a little quick release
lever somewhere in the brake system. If not, it's possible to add a
brake quick release to most types. Talk to your local bike shop.

BTW, this is a good source of info for lots of bike mechanical questions:

b. Is there supposed to be a flat washer between the bike fork's
cutout, and the cam mechanism ?
On the cam side ?
On the Nut side ?


No. You want the little teeth on the quick release bits to get a good
grip direction on the fork dropouts. The "dropouts" are the bits at the
end of the fork that perch on the axle.


That was supposed to be "_directly_ on the fork dropouts."
