Pump placement
« on: October 27, 2024, 11:15:19 AM »
I’m looking at pump placement solutions. I want to attach a pump to my Nomad frame. All three of my bottle holders are in use so I was thinking I might attach the pump and its holder on to the back of the seat tube, adjacent to the rear guard. I’ve a few solutions in mind but wondered what other Nomad riders did.

I always carry two pumps but want to take one out of my tool kit so I can then use an under saddle tool bag ( freeing up a bit of pannier space )
Suggestions and/or photos appreciated.
TIA

Here’s what one Nomad rider did to his great satisfaction, though I don’t know if you want to overhaul your setup this much: move two of those water bottles in the frame triangle to feed bags mounted on either side of the stem. The Decathlon feed bag, for example, is cheap, big enough to hold even a Nalgene, and durable enough to have lasted me over 20,000 km. (I guess the third bottle, if it is a mere backup, could go under the downtube.) Then, use the frame triangle for a frame bag, which really improves handling and comfort if you pack your heavier items there. The Ortlieb 6L frame bag doesn’t take up quite the entire triangle on my medium-sized Nomad Mk3 frame, so there is room underneath it to mount my pump on the top of the downtube.

For the last 12 years, I've remained very pleased with my Zefal HPX mounted vertically behind the seat tube, Ian. For photos and description, see...

Best, Dan.

Edit: Clips are available with some pumps or separately that mount between a bottle cage and frame bosses, so you can use both a bottle/cage and a pump in the same location. A search for "Lezyne pump clips mounts" brings up a number of examples.

A Lezyne mini pump came with my Mk2 Nomad in 2013 from Thorn. Not sure if this particular model of pump is still produced. The bracket is available on its own, SJSC part number 21560, say if you wanted to move the pump temporarily to another bike, and might be compatible with other Lezyne pumps. Pump mounted upside down to help prevent rain water etc getting inside the pump barrel 🙂

I've a pump clip on the same two bolts as the bottle holder.  They are on ebay https://www.ebay.co.uk/b/bn_7023567930
oops sorry Dan just re-read your post !

I now carry pumps where they can not be seen, in a bag I will take with me if the bike is parked up.  They are too easily stolen!

My pump is held to the bike with a bracket under the bottle cage.

On the seat tube it collects less dust than down tube mounting.

For many years I carried a pump attached to the frame, no longer. One time, in the middle of nowhere, a flat occurred, and there were many miles/time since the last flat. The pump failed due to crud buildup over the time since the last flat. After much work and water with the pump, I managed to get some air into the tire and limp down the road to a distant gas station. If the pump is to be mounted outside, protect it with something, perhaps an umbrella case sleeve, not sure they are good for anything anyways.

Ian,

My Lezyne pump lives in my Revelate medium frame bag, on the (shallower) left side rear.  It's out of the elements and away from prying eyes.

That's on my Mercury, not a Nomad, but the pump was in the same spot on my Raven.

Plenty of space in the main triangle for the medium Revelate bag and two bottle cages -- I used a large on my Raven.

I had mounted an earlier pump on the rear of the seat tube, but that was pinched.  :(

Cheers,  John

After having pump and/or water bottles stolen on toilet stops, since the late 1970's I put my pump in one of my bags, not necessarily one that I take with me.  And I use disposable water bottles.

Since decent small pumps became available I use one of those, either a very small Lezyne pump with aluminium barrel and reversible flexible connector that goes with my everyday toolkit, or on long tours where I know I will have to top up the tyres I take a larger Lezyne like the one in UKTony's photo.

The small one is only for punctures, it takes quite a long time to pump a fat tyre up to pressure, but I rarely have to use it. The larger pump is bulkier but more convenient to use.

As I don't do wilderness touring (no real wilderness in France and neighbouring countries) I only carry one of the two.

Great replies, thanks everyone.
I hadn’t thought about the theft issue but yes it’s unfortunately a consideration. Only yesterday a fellow cyclist witnessed the attempted theft of a ‘senior’ rider’s ebike. The gentleman was approached by two teenagers riding a Surron. Suffice to say other passing cyclists offered the alleged thieves some appropriate encouragement re the wisdom of their venture.

My pump is a comparatively minor issue. That said I do have a small frame bag that will take a pump. If I can site it somewhere on the frame I might have a solution.
Thanks again. It’s great to see photos of your bikes.

Near home I usually use a Road Morph G.

Bike touring, either the Road Morph G or the Lezyne Micro Floor Drive.

The one I use near home sees a lot of dust from frequent riding on gravel trails.  I have several bikes and have pumps on all of them.  When the Road Morph G starts to look pretty dusty, I give it a good cleaning, inside and out.

I put it on the seat tube, not the down tube, the seat tube area attracts less dust from the front wheel than it would if located on the downtube. 

Before I do a tour, I test all my critical equipment, such as tent, pump, etc., to make sure everything is still functional.  My headlamp for my head failed a couple years ago, fortunately if failed in my test at home and not on the tour a couple weeks later.

I like my Lezyne pumps except when they unscrew the valve core.  I recently discovered after several years of ownership the ABS system. This automatic bleed system is a rubber covered valve at the head which relieves pressure after pumping. This releases the grip and the valve core remains in place.  I’m sure you all knew that but as someone who rarely reads instructions I’d missed this useful feature.

Mine are older, do not have that extra valve.  I have to use a wrench to tighten my valve cores to make sure they stay in place.  I also used a thread locker on some of my valve cores, but I am hesitant to do that as you have to be careful to make sure none of it gets on valve seats that could cause a slow leak.

I think most of what can be said already has been, the days of the frame pump are over, they go missing too often (Two in my case) and better pumps have become available.  Add to that the trend for larger volume, lower pressure tyres and the ideal pump isn't the one for narrower high pressure ones.  it's no surprise that the one time gold standard HPX is no longer in production or that most framebuilders, inc Thorn, no longer include a pump peg as standard.
I had a HPX when I bought my Raven, in the location designed for it, behind the seat tube, it was at the time the best choice.  I now have the mini track pump style and they're better in every way except they're a touch more awkward to pack.  As I nearly always have a saddle bag, I carry mine attached just under the lid, in a purpose made bag.
I'm quite tempted by those USB rechargeable elec compressor pumps, I've seen one in use a coupler of times and been impressed.  I would want to carry it without a back up, but that could be the smallest of mini pumps.  For those not familiar, this sort of thing
