406 is for your normal 20" tyres. 20 x 1.0 to 2.125 sized tyres.
451 is for more slick tyres using 20 x 1 to 1 1/4 sized tyres.
Noted one type uses decimal numbering and the other uses fraction. Both are considered 20" but the fraction one is slightly wider in diameter.

ah i see
thanks

1)what is the normal rate for a bicycle tyre to deflate? one or two weeks?

2)Is it true if I cap the tyre valve tightly(with a metal cap) the air in tyre will not leak as quickly with a plastic cap?

3) How best to lock my $5,000 bicycle outside the corridoor, to avoid theft?

1) 1 to 2 weeks need to repump
2) no
3) multiple U lock plus chain locks

2) The air leak out from the 毛细孔... Just like those party balloon, you will see them slowly deflated.

You'd have to be an idiot to do that. A 5k bike's value is not in the whole bike...it's also in its parts. Some people might simply swipe your components and then you'd be introuble.

Yes. Rack must be connected using the wheel axle quick release. All screwed on racks cannot be used. They are disc brake compatible rear racks in the market. Not cheap thou.

Oh ok, are they going to be as expensive as those Topeak ones that just attach to seat post?

Do you have any disc brakes compatible racks in ur shop?
