Any problems with that location? Thanks.

unterhausen

you see that occasionally on custom frames, I don't see any problems

I have one of these jammed along my seat stay, I love the location because it allows me to pick up/carry my bike easily, I can quickly transfer the pump between bikes without transferring an easy to break plastic mount (assuming their seat stay length is similar) and I can quickly fill up my tires with little physical exertion, due to the pump's length.

How do you attach it to the seat stay? Thanks.

The pump telescopes a few inches, is spring loaded, and so can be simply wedged into place, also the ends are curved in a U shape so they won't pop out of where they are wedged.

No problem until you hit a large pothole and the pump comes out, lodges into the back wheel, locks up the back wheel and you fly over the handlebars.

unterhausen

you don't fly over the handlebars unless you stop the front wheel. When something stops the rear wheel, you slide to a stop and then fall over.

My pump is very secure, it requires considerable pressure to remove, if I hit a pot hole large enough to knock it loose I am already going to be crashing. Rear wheel lockups are unlikely to cause an over the handlebars type of wreck.

I've done seatstay and behind the seattube. Just gotta make sure it's solidly in there. You can get a Zefal Doodad (or just a hefty hook and loop cable tie) for added pump-in-wheel protection if you feel the need.

fietsbob

Brompton has theirs mounted there , all but the Titanium portions of the X versions.

pump pegs, like Zefal, strap on , and add a velcro strap and the pump wont go anywhere..

nashcommguy

This is true...I've done it.

I can vouch for this.

I just mounted my Road Morph mounted on the left seat stay using the mount it came with and zip ties. Seems quite sturdy and frees up another water bottle spot.

Does a pump mounted on a seat stay get a lot of road grime, (I've got full fenders and ride in all weather), and would that adversely affect the pump's function or longevity? Thanks.

This doesn't answer your question, but I'm having a little trouble picturing how you're mounting the pump so that it can't move around on the seat stay and jam in the wheel. I'm pretty happy with the Topeak mount that puts the pump to the side of the bottle cage on the seat tube.

Plenty of room between crank arm and seat tube. This bike is the worst fitting bike of all I have though because the bottle boss mounts are really low compared to other frames.....which places the FD clamp in the way. It's a close fit for sure.

Here are a couple of pics.





The bottom pic shows the black mount that came with the pump. It comes with rubber pads that sit between the mount and the seat stay, and the mount is fastened with two zip ties. I added a couple more zip ties to help ensure that the mount doesn't slip. The set has worked well on some bumpy roads, the mount doesn't move, and there's no heel strike.

Whoops, "seat stay" my mistake My brain heard something else obviously.

I use to mount a pump peg off the seat tube on my custom bikes just for this purpose. It started when I built my first CX bike and I wanted to get the pump out of the way so I could port it without interference. After that it just made the most sense......

Not on my commute bike, but on my Calfee Tetra I have a Topeak Road bike pump mounted on the left seat stay. Plus I have a small velcro strap that goes around teh pump and the stay, just in case. It's really pretty solid there and I've never had any problems with that mounting location.

So I think we've got the same mount -- I used the zip ties to attach it to the left side of the seat tube in much the same way.



Not saying there's anything wrong with your setup (I like how it makes use of otherwise wasted space), but you don't have to sacrifice a bottle cage to mount the pump on the seat tube.

Scott,
Nice set up.
My bike is smaller, and my Road Morph pump is too long for my seat tube. And I didn't like it under my top tube, because then it interfered with extraction of the water bottle. I guess the down tube could've been another option, but my down tube is rather wide, and the mount didn't seat as nicely.

ThermionicScott 

Thanks! I used to keep my pump under the top tube, and I agree it's a sucky location for one. Gets in the way of your water bottles, and prevents you from lifting the bike by the top tube easily.

Iuse the same location on two bikes. The only problem I have is water splashing on the pump and settling inside the handle.

xtrajack

I don't have mine mounted on the seat stay, it is the seatpost. I only have one bottle boss on my bike. I have my U lock mounted on my seatstays.

pdlamb

I've got two Road Morphs on the seat stays of two different bikes. No worries for me! Much easier to transport, too.

Note both of these have the newer clip on and velcro attachments. I think my older one (slide in and clip) has come loose once in, oh, 8 of 10 years, probably because I didn't slide it all the way in.

I've never really noticed a lot of dirt, even though one of the seat-stay mounted pumps is on my rain bike. It's on the forward side of the stay, and of course fenders reduce spray from the front wheel.
