Hello I need help
 

Can somebody please tell me what size pump I need to blow up my tires?😉

Medium.

Don't you need to know the size of his tires, before you answer with such brazen recklessness?

Most pros use C4.

As for pumps, it all depends on weight, height, age, experience, and body mass index. If you are 17 and weigh 320 lbs. you cannot pump up your tires. Otherwise, I am sure there is info available at school.

Do you miss the guy already?

I've found medium works with most. Sure small might be better if you're running with 16s and large is best for 38s, but medium is a good jack of all trades.

Exactly. Also, does the person wish to pump at home, or on the road.

A good floor pump will pump up a variety of tires.

For narrow tires (23mm, 25mm, and maybe 28mm), go for a high pressure road specific pump.
For wide tires (35mm+, MTB tires, etc), look for a high volume, low pressure pump.

Full sized frame pumps are nice, but have fallen out of favor recently.

All of those people advocating medium pumps for large and small pumpers are just plain wrong.
Pump length should be 83% of forearm length*, as measured from centre of elbow joint to grip axis. This ensures that the angle of arm movements throughout the pumping cycle is optimized.

* According to the C.O.N.I. Manual

Ok before going into any misunderstanding this just a little Monday humor,sorta like troll humor ,,I thought somebody was gonna ask why I wanted to blow them up ,have a great day ,,,, its raining in New Orleans

Do you want to inflate them or "blow them up"?

Why are still using a pump you luddite?

Welcome to the 21st century.

You can thank me now.

I heard that method was banned by the UCI.

Heard about em, never really considered them,, are you riding them what kind of price do they have?

Aren't there mouth-to-valve adapters on the market? Lower carbon footprint versus a pump. And good pulmonary exercise.

:lol:

My favorite was the mini frame pump that was made without the internal guts, I purchased it from Walmart. 3 hours later my tire was still flat but I now look like this!

to tell you the truth I think you have a legitimate case here, I never seen such a thing , now you might have to get some injections on that limb,,,,

Bikepro ,,, you really are a Pro,,,,

Best thread in weeks. Just ordered a new medium pump on Amazon after reading this wisdom!

Well, good ... but did you stop to consider whether to get a forward- or reverse-action medium pump? This choice, as is well known, is contingent on whether you install your tires and/or wheels forwards or backwards. For example, if you install your tire backwards on your rear wheel but your rear wheel forward, then you'd need a forward-action medium pump. But then of course if you did do that your bike would be unable to move ... obviously ... or not ... even though you'd be able to blow up your tire.

I believe Bikecyclecycling™ just ran an article explaining this very elementary error.

Great article, just bought another pump to cover both possibilities. Did you read about the extra large two person pumps for the tubeless MTB tires? Also good stuff!

Good decision. I didn't see that article, but I have heard about these: are they the ones that use a de-mountable eight-foot lever placed on a central dual-piston pump-pivot, thus permitting quick inflation of mtb tires, including fat bike tires, quickly and efficiently? I understand that the lever itself folds down to four feet, so that it can easily be strapped across the handlebars when bikepacking.

Well, I understood, and liked, it. Two or three posts to your credit, tho, and it woulda been locked and banned methinks...:)

Seemed to take an extraordinary amount of time for me to pump up my tire...

When are manufacturers going to (finally!) get with the program and produce self-inflating tire systems for bikes? All that wasted motion (front suspension? rear suspension? cranks? steering?) could be put to use compressing air which is then routed to the tires through hollow spokes (two per wheel, for redundancy), with an over pressure valve (OPV) to avoid over-inflating the tubes. Really efficient systems could even overcome most pinch flats or small punctures. Simple.

Odd you should mention this: here you go This self-inflating inner tube is 'making the impossible possible', apparently - BikeRadar

The utterly stupid over-complexification (like that one?) of the bicycle continues apace. Seems an appropriate thread in which to bring up this latest 'invention'.
