View Full Version : Pump mount braze-on poll: Seat stay vs tt

Considering whether to add seat stay braze-ons for pump on a new rando bike and curious about peoples preferences.

Considerations:

With seat stay, you are locked into the one frame pump size. It would probably be a Lezyne road drive. Very light, though I've had a couple come apart on me. Recently have been using the Lezyne micro floor drive. Seems a bit sturdier and makes inflation quicker and easier. The seat stay mount looks clean, but maybe a little too... I don't know-dainty? too constructeur? I'm already going down this road with the dainty little Compass seat tube mounted tail light...
I suppose if I were committed to the smaller Lezyne this would be an easier choice.


Top tube pump peg mount allows full-sized frame pump which is nice, and there seem are more options. I have a Silca. Its nice, though heavy. Fits without need for velcro strap. Shouldering the bike is awkward. Look is not as clean.

Seat tube mounting underneath on the water bottle boss via plastic clip that many pumps come with seems perfectly viable, with multiple options for pumps. Does it bother me to have a plastic mount with small velcro strap on a custom bike? Maybe.

Am leaning toward tt pump peg and no seat stay braze

Depending on the frame size you can get a silca frame pump on the seat stays as well. This is what I have going on and it's the best of both worlds, you get to have a full sized frame pump and its out of the way.

Aesthetically I prefer the look of a top tube frame pump even though its visually more noticeable, at least looking at drive side. Maybe its just me being ocd about things being symmetric. I totally get the aversion to a plastic mount thing off bottle bosses. Seems too Fred/commuter.
One downside w/ tt pump is makes using a frame bag problematic. That might not be an issue to others, but rando bag, + jandd frame bag + tools in a small saddle bag is a pretty good bag setup for me I think.

oh and ps - i wonder how many top tube compatible frame pumps will be available in 2 - 3 or more years time. Topeak isnt making their frame pump any more (you can get them at Probikekit) which I think just leaves $$$ilca, and I guess Zefal?

with the seat stay lezyne braze-on, i think you need to modify the lezyne pump to add a spring, to hold it in place, yes?

i wouldnt do that, as you're then locked into a specific lezyne model and if they stop making it, you're SOL.

i like frame pump in the traditional top tube location, especially if you get a tight fit and it holds solid there.

+1 for top tube mounted.

Although I was able to mount one on the backside of my seattube, tucked between the NDS seatstay and chainstay, just far enough away from the tire. Kinda cool looking.

It's not really a modification per se. You add a spring. Removing it and adding it back again takes seconds.

It's horses for courses. You don't want a top tube frame pump for any bike you might use a frame bag with. And let's be honest, a sleek Lezyne mounted along the seat stay protected by said stay looks cool.

i wouldnt do that, as you're then locked into a specific lezyne model and if they stop making it, you're SOL.

True, but this is not a new risk. I wanted a pump for my ~1950 Jack Taylor's pump peg. Found a new one online for $25 or so.

Problem w/ top tube mounted pump is when you need to carry the bike, pump slips, bike falls. If you are carrying frame without wheels it will bang the fork drop outs on the floor. Been there...
Top tube is a busy place. Seat stay isn´t .

Top Tube without a doubt. I need/prefer the second bottle cage on my seat tube.

I use Zefal pumps on pretty much all my bikes that have a peg. They work great when needed, stay put just fine, and I carry the bikes by the top tube with the pump in place all the time with no problems.

For what it's worth though. I can, and do, also use the Zefal pumps in the seattube position for a couple of my bikes without pump pegs or with a number's tab on the bottom of the top tube. No issues with it staying in place there but it limits me to one water bottle cage.

Although it does make accessing the pump a bit of a hassle, my TT mount works fine with a frame bag.

I think the TT looks best. HOWEVER I don't like it in practice. I hate straps, and I also hate to pick up a bike via the TT when a pump is on there.

Not as slick looking but allows for a full size pump - and I first saw this done by a super bad@ss rider so I've always like this setup...

Good comments all around. I think full size top tube mount looks great on a steel road bike. I have a Silca on my mine. But the big long-hose Lezyne mini-floor pump does not look out of place underneath the water bottle cage on my gravel bike. As far as fitting a full sized pump in the rear triangle of a road bike, it's cool when that works, and looks sort of rad, especially on an old steel race bike, but in my mind does not have the look of something done by design. That Sachs is pretty close though.

I know longer have frame pump on bike. But when I did, it was TT. I always had nightmares of hitting a bump and pump popping in to back wheel when mounted under/along seatstay. In the nightmare, wheel was trashed, rear end/stay effed up, and I got hurt. Just my take.

an idea that I saw recently that never would have occurred to me is to put bottle bosses on the seat tube. Then just use the bottle boss mount that comes with the pump. I'm thinking about it

tee hee

I did it that way for years on a DeRosa w/o a pump peg..Might use an old inner tube section over handle/body tho..cuz in rain, it fills with water..and rusts.

Another idea is using a drill to make a wee counter sink in head tube, JB weld a ball bearing there=pimp peg..

Well, if it ejected into the spokes that could be quite bad.

I had a small pump drop out the back once and go into the rear wheel. Pump shattered, rear wheel jumped, spokes broke. At speed with a bigger frame pump like in the pics I would expect the results to be worse. Just my 2 cents.

I have secured a pump along a seat stay before but with lots of velcro straps to be "safer"

It´s less possible for a bigger pump to fall between your spokes. It could fall between tire and seat tube. Maybe. And then you would slow down. It never happened but .. you know... on the internet things may happen.

I've had top-tube-mounted pumps fall off and go into the cranks, the rear wheel, the front wheel. It's a chronic problem on small frames (which I ride) because there's basically no head tube and the seat tube is so short you can hardly fit anything there -- might as well go with a pocket pump. Just pinch your knee into the top tube in a descent or fast turn and the pump wants to shift and pop out.

Frankly, I just found that the long pump wasn't that usable. It marked up the frame, the braze ons tended to rust, the pumps never looked as good as the frame (fashion statement about my bikes), and they never worked all that well. The best ever was the original Silca with the Campy steel head, and I could actually fill a tire to pressure with it.

Today, ... a mini pump plus CO2 cartridges. I think that's the real answer here. In the winter the cartridges, spare tire, allen wrenches, etc. all go in a split water bottle in the seat stay mount. In the summer when I need water there, they go in the smallest saddle bag I can find or in my jersey pocket. It's safe, it's compact, it doesn't detract from the look of the bike, and it works fast and efficiently. Carry an extra air cartridge or two to cover multiple flats, and use the bigger cartridges, if you're on fat tires, and you're good.

It would be cool to see someone make an alloy pump that came in two to four threaded sections so it unscrewed and became short. Then you reassemble the chamber and the central drive shaft and you're ready to go. It could pack into any small bag (and even come with one that had room to accommodate a spare tire and even cartridges and a couple allen wrenches -- Silca, are you listening?).

11.4, do you have a favorite CO2 inflator head unit? Right now, I carry a mini pump, but have been thinking of adding CO2 to the mix. What inflator do you recommend? Thanks!

I've been using the green Innovators head for several years. It has a push button air release mechanism, so you don't have to screw it in or out slightly to manage air flow (which the black ones do). The only problem with the green head is that if you pull the head off wrong, the o-ring can blow out and then it won't work.

I'm now carrying the Silca, mostly for the feel, but it certainly does work well. I also am using the Silca CO2 cartridges. Silca claims that they have more capacity in a given size because they are really filled to capacity. I don't have many flats so I don't mind spending a little bit more for something that's important to get me home when a flat does occur. Overall, I'd recommend this to you at this point. You can use the smaller cartridge even with a 27-28 mm tire, and two cartridges plus a head are both lighter and more compact. I strap them together and they, with one or two spare tubes (Specialized Turbos or similar thin-walled ultralight tubes) and a Park instant patch kit, make for an extremely small package. I can wrap everything together in plastic wrap and it all makes a package smaller than a pack of cigarettes.

On some longer group rides I'll carry a short mini pump. It's a pain to get enough air from it, especially with fatter tires like 27-28 mm, but it gets you home. I have one of the nice Blackburn carbon fiber ones plus the short Silca one. Both are good. Anything that sticks out of your rear jersey pocket by more than an inch or so is destined to get lost sooner or later so I go with shorter just to know it'll be there. The mini pump is there for when you run out of cartridges or have given cartridges to other riders. We've all had rides where a pace line goes through a field of broken glass and half a dozen riders have flats, sometimes double flats.

Yeah, whatever. I'm sticking to the school of "It's a bad idea" but to each there own. Totally broke a C.F. seatstay by the spokes rotating a broken RD through it, I'm not messing around with anything I perceive dangerous around the wheels.

Luckily it's not an issue for me since 95% or so of my bikes have pump pegs like they should, LOL! :banana:

I have left a pile of pumps in the woods from gravel biking, so all my bikes have the pumps attached with double-sided velcro now. Wrap around the bike tube first, and then around the pump so it doesn't take too long to remove or reassemble the pump.

In the 80's most frame pumps were mounted under the TT which is why most bike manufactures put a pump peg on the HT near to the TT, this left plenty of room to put braze ons for bottle cage mounts on the ST and the DT.

So I vote for wherever the pump peg is that's where the pump should go.

By the way, shouldering the bike with a TT frame pump isn't a real problem, I've done it by simply removing the pump, then shoulder the bike and carry the pump with my free hand.

I think that a Lezyne on the seat stay is a very cool idea and I may well see if I can get that done on my next custom frame. The only real downside IMO is that it somewhat 'ruins' the lines of the frame.

On the other hand, this method works pretty well....it's out of the way and not really noticeable.

Interesting picture, how did you get a Lezyne pump with green anodized bottom portion of the pump to exactly match your frame color? I have the same pump but the only color it came in was all polished aluminum and I don't see that color on their website.

And besides custom paint, it'd be so cool if KEdge or Tom Kellogg or someone like that would make a very slick, trim bracket that fits under the seat tube bottle cage like the ones that come with the pumps, but is made of stainless and is paintable, subtle, and uses some kind of cool clip to hold the pump in place. Then color match the pump, the bracket, and the frame. I'd ride that.

Silca? How about it?
