What is that second upper tube?

I think that's a frame pump, familia.

95 percent of the time a Frame pump

Other times, a double top tube, for super fatasses. Think Gargan kind of fat on on a black diamond downhill run.

OK, I know about the "shocks pump", but a """frame pump"""? And how is that supposed to work?

It's a frame pump. It's become fashionable to get one color-matched to your custom weekend-rider.

But only if it's a $165USD Sylca.

It's a pump that attaches to the frame, not a pump to inflate the frame

It's a pump for your blimp bike

LMAO,
hoping this is bait.

It's a blimp attached to your bike that carries all your luggage.

I'm pretty sure matching frame pumps have been a thing since the 60's and 70's

why are they so huge? my lezyne mini pump gets my 700x25 tire to 100 psi in a minute.

maybe your mini pump is a good one - most fucking suck though and will eventually fuck you over.
a full size frame pump is pretty bullet proof though.

I think its the most popular pump on chainreactions, looks like spending 35 dollarydoos on a pump was worth it. I even got a pinch flat today.

nowadays the Chinks have graduated to motorized bikes

CO2 does leak out over the course of the next 24 hours. However with a road bike it's still so much comfier than a mini pump because you get the tire to proper pressure fast.

Bullshit

Just a reminder that CO2 is a "get-you-home" solution and it's assumed that once you are home, you'll let it out and repump your tires with air.

>>1026090
That they have, but they've only recently become FASHIONABLE.

I work in a bike shop and I used to overhear two particular salespeople talking to customers about this phenomenon. Both of them would explain it by saying that, "CO2 is a gas, so it leaks out of the tube faster than air."

It's alarming how dumb people are.
