Putting frame pump on chain stay?

Do you guys think this is a good place to put a frame pump? I know there are other places that might be better, like the top tube, down tube, water bottle cage bolt area, but I have my personal reasons for not wanting them there.

The main problem I can see for this is the pump might rotate in towards the spokes. But the velcro scrap is pretty firm, and it would take a crash situation or someone bumping the pump for that to happen. I think the chances are small. I also think the pump might get dirtier quicker being down there.. what do you think?

Yes, it’ll get dirtier. No big deal.
I’d put it on the underside instead. Let gravity help center it.
And I’d use a strap/clamp at either end as further discouragement to turning.

If it was to go into the spokes, you'd have a big mess.

With the direction of tire rotation, perhaps on the front side of the seat stay, at least if it went into the spokes, it would be more likely to ping off of them until you noticed rather than getting jammed into them.

While the chances are small, the way to avoid accidents is to eliminate even the small chances. Since the pump is in a position to be easily struck by your heel as you're pedaling, it just looks like an accident waiting to happen. Why take chances? Since you've limited your choices to not wanting a pump on the three main tubes, why not go with a mini-pump that can be held in a seat bag? That's the solution I used, and mine fits in a small-sized seat bag.

That's a Darwin contender, IMO. Pump looks small enough to carry in your jersey pocket if you really don't want to mount it properly.

I like look of it. If there were two brackets holding it, and they were both bolted so they wouldn't move, then I might consider that approach. I'd need to eliminate any risk of the thing rotating into my spokes.

Yeah...count me with the group that would NOT put it on the chainstay. Regarding your comment about it getting "bumped" into the spokes...what kind of shoe/pedal system you use on that bike, and how do you get the shoe off the pedal? Sounds like an irrelivent question, but when I 'twist' my clipless shoe to unclick I usually twist the heel inward. Frequently it will hit the frame, and 'could' push something mounted there into the spokes. I think that I'd mount it on the seatstay before I'd mount it on the chainstay (not that I'd prefer the seatstay either).

One more vote for, at the very least, rotate it to the bottom of the chainstay. Far better, mount it somewhere else. It is indeed a destructive accident waiting for an opportunity to happen.

Could be worse, I was on a ride on one guy thought it was a good idea to mount the pump to a fork blade.
I would do neither since I've had many a pump decide to jump off mid ride..

With some thought and a reliable set up I'd be comfortable with it on the bottom of the chain stay. On top as pictured not so much.

I agree with the previous ^^^ opinions. How about alongside your seat tube? I've carried mine this way for years with no problems.

Brompton has pump pegs on theirs, and a pump Zefal provides for them , quite well made to be keeping the dirt out.

It is a S/V pump..

a touring bike may have a frame fit pump along its seat stay , builders add pump pegs..

Mine are on the front/lower side of the seatstays. Out of the way, no issue if they're bumped into the wheel -- although the one time I remember it happening, the racket had me fixing it in a hurry!

Indeed. I'd worry about my heel knocking it into the spokes when clipping or unclipping from the pedals.

This is how I mount my Topeak. Works great.

I think I learned to twist out to get the feet out... but I guess I never think about it. Been doing that since experimenting with clipped in toe clips.

However, I may twist my feet on the pedals when bored.

When carrying panniers with short stays, I like to keep most of the rear triangle open to prevent heel strike. Chainstays/Seatstays should be moderately out of the way, but still close.

Yep... stuck in spokes in rear means skid, and perhaps a damaged wheel, and or frame members.
Stuck in spokes on front means a quick flip.

Although, again one should think about wheel rotation.

In front, chances are it may ping the spokes. In rear, more of a chance to get stuck in the spokes.

Seat tube or down tube or under the top tube. Any would be better than the chainstay

Niagara Cycle has the one for under the top tube as well as several different ones for under the water bottle.

Yes, but OP has personal reasons for not putting it there.

Maybe if he considered this clip (at 1:45) he might re-think those personal reasons!

That pump on the stay looks like a bad crash waiting to happen.

I just remembered I had this other pump holder, and found a better place for it. I didn't want to use the holder that goes on the bottle cages because I wanted to be able to roll up to a race, and take the pump off quickly, and race, without a frame pump holder messing up my drag coefficient (yea I'm kind of OCD about that now). that's why i went with velcro. easy on easy off.

thought about just putting it in my jersey pocket, but I realize i'd often forget about it, and on the days when I wear kits without pockets, i'll be without a pump. that concludes the quest to solve my first world problem. thanks for your participation
