What's the deal w/ bicycle tubes? Do any of 'em hold air for more than a few days? Doesn't make sense that all of 'em in the nicer bikes we've got Fisher / Ellsworth / Giant / Cervelo / Orbea... they all leak big time.

This can't be right. Does somebody make a tube that holds air for at least a month or two?

They lose air at the same rate as any other tubed tire. Its just that the volume is so small you notice it instantly.
I pump my tires every few days when I'm commuting.

...and in the case of road tubes, the pressure's a LOT higher inside than out.

Whichever law of thermodynamics it is sez things have a tendency to move from areas of higher pressures to areas of lower pressures...

That, and they're doing it to piss you off. I heard em talking. :razor

:D

hah, the old days, with silk sewups aka tubulars, they had latex inner tubes for weight which held air for /hours/ before needing pumping.



whooot! Tour of California Stage 2 ends in downtown S'Cruz, this should be a kick!

Maybe you're just too far up on the Hillside. I don't seem to have that much trouble down here in the lowlands. :lol3 Or maybe it's just that I'm mainly ridin bikes with softer tires these days. I think on the Pugsley I'm runnin about 5lbs in the front and 8 to 10 in the rear. :wink:

Besides, having to keep pumping those babies up will keep you in shape for that lovely little wife of yours. :evil

More fun and folly in the far and frozen North, Mark H.

Been wanting an Albatross bar for a long time myself; just put one on my old daily ride POS steel Ross yesterday. Rode in to work today and I love that sucker! If you need a taller stem just get one. I put a taller stem on an old Trek I have and that did the trick for me. The Albatross is just perfect on the Ross for a stem that is not super-high.

Hey AKDuc, how you liking your Pugsley? What kinds of riding are you using it for?

As for tubes holding air, if they're any ultralight variety they'll lose pressure way faster that heavier ie. thicker tubes.

Tubies are still great, the new ones rock. I used to run my Zipp 404's at 120-130 and still had a super comfy ride

It looks like there's too much road-bike banter here to read the whole thread, so I'll just post up my 48lb bike. I'm pretty sure it has more travel than my XT350 did. :lol3 No I don't ride uphill very much!

Here's my last two big bikes that I didn't pedal uphill much either, but my 640 still has more travel:lol3 :lol3 :lol3

Where the hell do you ride a downhill bike on "Tha Rack" dere bye?:lol3 I thought you Newfies had to go to Quebec to ski.

skibum69 12-06-2008 09:02 AM

Well Calibre, I will admit we don't have the vertical of you left coasters but we do have some decent skiing terrain on our west coast and some fun shots right in town for the really bad jones'ing days

Signal Hill St. John's

As for DH, we have a whole series of trails just 5 minutes from downtown St. John's! There aren't any really easy trails and plenty of structures I won't try for air time.

Plus we have excellent technical XC riding all around with plenty of rocks and roots, a nice challenge on a single speed

I'm not manly enough for a Pugsley.

I don't have a chance. That little fart is constantly running or biking or swimming. Yesterday after work? Swim. This morning? Spin. Right now? X-country skiing.

With a similar dedication myself I've just polished off a couple of Carl's Jr. burgers and spared a moment to think about what it would be like to be buff.

The winter wonderland kind, thank you. And I'm LOVING it! :thumb

It sinks in the snow LESS than a skate skier and it smooths out a rough foot traffic pock marked trail really well.

Oct marked my 1yr anniversary of not driving my cage to work. :D Mark H.

skibum69, I was just being a Whistler/The Shore-snob. Hell, if the kids in Edmonton can justify having DH bikes, then anyone can! LOL. Nice looking ride spots you've got. You need to come out here with your favourite DH bike and ride Whistler for a week. :) I haven't been up there since my daughter was born, but IIRC you can now do over 5000' of hi-speed vert in one run!

skibum69 12-07-2008 11:27 AM

Hey Calibre, I used to be a Troy Lee Designs rep for bike & we had a sales meeting at Crankworx one year. Of course I brought my bike with me. Yup, good times at Whistler! Thanks for the invite, I'll let you buy the beer:lol3 :lol3 :lol3
