Well Maybe Windows is Bearable ! Unix Rules !
Today while doing my Communte to work , I had a flat , Basic snake bite. get out a replacement tube that I carry it a brand new 700X20 Tube. I un roll it and it is a Schrader valve ? who in there right mind would run a schrader valve on that narrow of a tire ? Since I was commuting I also carry a spare tube n my Back pack. and that had a presta vavle on it so all was good.

If a boob buys a tube in the forest and there's no one there, does it make a sound?

Impossible, who is the boob buying the tube from? Unless there are tube vending machines, which is really kind of silly.

I bought 5 at once at the LBS , and just took 5 from the rack. and they are 700X17-23 .

What wrong with commuting on a 700X20 ? :)

And it was the front tire which is a 700X20 the rear is usally a 700X23 although right now it ia a 700X20 that is closer to an 18 that a 20. I really should change that one of these days .

You are asking for a flat w/ that tire.
Why don't you just get a 18mm Slick while you are at it. ;)

Not if you make sure you keep the tire pressure up. :)

17? Damn.... It's been a while since I owned a road bike. Almost 10 years now. :eek:
Back when I was a roadie, a 19lb bike was INSANE. What are they down to now.. something like 14?

Oh, and here is a way to remember them...
Presta (the skinny one) has the little thing on top that you unscrew and PRESS to put in air. Presta/Press

Well, I wish I rode on the glass-smooth roads you are fortunate to commute on. 20mm tires would break my fork on my ride...

seriously tho, you wouldn't be more comfortable on wider tires?

Also, I don't think 20s are any more efficient than 23s. The contact patch is pretty much the same, yeah? I guess 20s could be a slight bit more aero?

Hell, 23's will get you fewer pinch flats...

I use Specialized Armadillo Elites, 700x23 and only 260g each due a slightly lighter casing (compared to a regular Armadillo) and a folding bead.

They ride extremely well and I have not gotten a flat yet. And my ride is going through the dredges of SF...

The question is, who the f buys tubes without noting what valve orientation they have???

I only gotten 1 flat on my roadbike. I put a dollop of Stans sealant in each tube, flat was not received with this setup. Seems to work like a charm.

INSANE these days is under 8lbs, average serious roadbike i,e: not weight weenied out but with light parts is around 16or so.

um, ya, steel rimmed touring bikes are probably the target market for narrow shrader valved tubes.
