Do I need a Pump peg?
 

Hi,
Are there any full size frame pumps out there I can use if I don't have a pump peg?

Thanks!

What type of bike do you have? Where are you putting your pump?

There are pumps designed to be installed along the seattube on vintage steel bikes, reaching from the bottom bracket to the top tube. No peg required.

On the other hand, if you are putting a pump along the top tube, then it will hold in the acute angle of the seat tube/top tube, but requires a peg near the front as the obtuse top tube/head tube angle won't hold the pump.

Personally I dislike top tube pumps as I like to carry the bike by the top tube.

Some bikes with oversized tubes, and rounded/webbed corners won't fit a pump like the old steel bikes.

Frame pumps are nice for show on a classic but no longer practical with the mini pumps and CO2 cartridges now available. The classic frame pumps were often painted to match the frame thus showed even nicer.

Silca Impero does not need a peg, Park PMP5 does not need a peg, and I don't know if Zefal make the HPx anymore, but their last model did not need a peg, either.

PMP5 is cool because it adjusts length to fit a wide range.

My experience with Zefals was that even with a peg they needed a strap to be truly secure. I moved on to a mini pump that mounts beside the bottle cage. Works well enough.

Me too!

I'm having a steel frame built to fit, I'd like to mount on the TT. Seems like I should just ask a peg to be added. Any downside to that?

No...except that then you need to have a Silca Impero Ultimate painted to match!

If you are mounting it on the top tube, then you need a peg.

Two types, a true "peg", vs a little nipple on the head tube. I'd probably just go with the little nipple on the head tube.

Downsides... a couple of grams of weight?

As mentioned, I never really liked a top tube frame pump as it got in the way with carrying the bike.

Another potential downside might be wearing paint at the pump attachment point.

Weird, is your's sized correctly?

I'm running them on about 20 different bikes and have yet to have an issue with one. I have 3 zefal pumps I rotate among the rides the range from 53 cm to 56 cm frames. I just pick the pump the fits properly. Probably around 13,000 miles just in the past 2 years over rough roads and I've yet to pop one off.

just my 2 cents....

The Park PMP5 is designed to fit the TT, and doesn't have any accommodation for a peg.

I don't think Blackburn even makes a frame pump anymore - this one fits nice, but I don't trust it without the strap even WITH the peg.

Funny. I've lent my frame pump out many times to bail out mini pump and CO2 users (or just speed up their pumping.) I guess we have different ideas on what is practicable. To me, a bike that cannot fit a frame pump isn't. (And you will never convince me that it is all that difficult to design a carbon fiber frame that can cleanly stow a full sized pump. Marketing says "do it", the egineers get to work and in six months, they are on the sales floor. What we have is marketing telling the engineers to make sexy, not real life practical and we cyclists line up like animals at the trough and say yes.

Minor rant, rant! (Minor because all my bikes are metal with with skinny tubes or brazed/welded pump pegs.) I do have a dead good frame pump; killed by a rider I lent it to while I wasn't watching. He and others had emptied the collective bank of cartridges on a rough gravel ride.)

He said “practical”. You said “practicable”. They are not the same thing.

I run my pumps pn the top tube with straps. I've put almost 200,000 miles on Zephal pumps since 1973. Probably 4 have been run over by cars after falling off. (One still worked after I rammed a dowel into the barrel and sorta straightened the handle. Had a nice arc to the pump stroke and went quite a few more years.) Since the pumps are good for an easy 50,000 miles each, it makes those $2 straps look like a sensible thing. (I run them under the brake cable housing, around the pump, then the velcro over the housing to close. Opening is easy and it doesn't fall off.)

I used the horrible, awful, useless Silca pumps and the much better Zefals for many years with pump pegs. Never dropped one off the bike despite never using a strap. Trick wth the Zefals was to get the right size, big enough to be highly compressed when mounted.

I don't have one of those. It looks like a nice pump. However, it apparently does have provisions for a peg. What it may not support are those cup shaped clamps.

If the TT and DT meet on a small frame, then no peg would be needed. Otherwise, perhaps the strap would substitute for a front peg, but if I was having a frame custom built/modified, and intended to use a TT frame pump, then I'd get the peg.

Ah, I stand corrected. Sorry for the mis-info, and thanks for the correction.

Go for it. Depending on the size of your frame, you may want a peg hanging under the top tube, or a "nub" on the head tube.

If your frame's on the smaller side, the top tube, down tube intersection may be tight enough that a peg is not needed at all.

Yeah, for awhile at first I was using a velcro strap. But I swap bikes pretty much daily and got too lazy to move the strap and stopped using one. Maybe if I ever eject one I'll worry about it.

Heck, as I think about it, I've ejected several water bottles over the years and still don't do anything special about that either....

You will need a peg if you want it under the top tube.
Don't need one if mounted along seat tube.
Some can also fit down inside of left hand seat stay. Tyre clearance usually the issue for putting it there.

I've always thought these on the seatstay were cool.

What bike do you have? Important information. I own 4 Zefal HPX pumps that I use on various bikes. They come in different lengths. I have an HPX4 that fits under the top tube of my touring bike(it has a small peg on the head tube). I have 2 HPX3's that fit my 54 cm Look 481SL along the seat tube(no peg). I have an HPX2 that fits my size large Look 595 along the seat tube(no peg). Whether you can use a pump like that on your bike depends,...on the bike you own
Zefal still makes the HPX:

Truly a classic, when I am out on rides with friends, when someone has a flat they turn to me, "he has a real pump"

Maybe we should have a "Show your pump peg" thread

Pump pegs also on the seat tube
