pump for 100 psi for Bruce Banner

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

You're 145 and you want to hit 100psi? Are you running 19mm tires?

Seriously, though - that's a bit much.

just 25 gp 5000. it's just an easy round number to hit and I don't like pinch flats. I grew up on bmx bikes, seems like flats where rare way back when. First time riding a road bike was last year. In first two weeks got a flat from a simple bump in the road. The cyclist set me straight that I got a pinch flat and should ride at 100 psi. So that's what I have been doing. Before ever ride use the full size pump to pump up to 100 psi.

Think 80 psi with inner tubes and gp 5000 25 mm tires is good enough then ?

or is the day I convert to tubeless and stop worrying about pinch flats ? ha-ha

My pump of choice to attain high pressure is my trusty Zefal HPX, I can get well above 100 psi with it
Pardon the bold , eyes , had a Zefal years ago - found a source online for a new one - 3 models depending on distance between head tube and seat tube - question : is the hold by spring tension at both ends or is there additional hardware required ?

Why do you need a 100 psi? Holy crap. At best 70-80 psi will be much better. More comfortable ride and the tire will conform to things that will want to poke through it.

Zefal has always been a great pump - I talked to an online retailer that sells them , they said it only attaches to a brazed on peg near the bottom of the seat tube - I'm guessing Look bikes have those pegs but you also show a pic with a top tube mounted Zefal - how is this mounted , did you have to buy a peg attached to a strap for the top tube ?

There is no need for a peg at the bottom where the seat tube and down tube meet at the bottom bracket. The top tube mounted pump fits onto a pump peg on the head tube and into the angle between the top tube and the seat tube with no fitting needed. In both cases the pump is held very securely as long as you have the correct length pump for the frame in question. I have 3 different length pumps for my various bikes. In the picture of my Limongi in a previous post you can clearly see how the bottom of the pump fits into the seat tube/top tube junction. That end of the pump fits into the seat tube/downtube junction the same way

The retailer Rivendell Bicycle Works does offer the pump in three sizes requiring the distance from top tube/seat tube junction to the seat tube/down tube junction - my bike , Litespeed Tuscany 2003 doesn't have a pump peg on the head tube - thanks for the explanation and additional pictures .

Well your test was faulty. When you attached the second pump the air had to fill the hose first.

seriously ? ha-ha

I let the air both times.


The new pump with the gauge can hit 80 psi. My old pump is good to about 50. I tested both pumps several times. Each time I let the air all the way out.

Ok, that was not how the OP described it. 50 lbs would be low for most.
