Seat bag/pump rec

[mass_biker]

When I’m riding out in the sticks, I hew to a belt and suspenders approach to emergency inflation.

So, I’m looking for a way to carry a backup to C02 on my soon-to-be-back-in-service Parlee (Z5 SLi) - no fitment for a frame pump there and I’d rather not have the mini frame pump side-mounted rattley-bang to a water bottle cage.

While I do usually pack a second Co2 in my jersey pocket tool kit, wondering if there is a more elegant/durable solution that piggy-backs on my use of a dedicated seat-bag. So, I’m looking for a saddle bag that could hold a small mini pump (Silca?) if so, which ones - the Arundel “Tubi” seatbag looks long enough to fit a minpump? Or maybe this is a use case for one of those rechargeable inflator-jobbies?

Welcome any feedback or first-hand experience.

Not really what you asked, but I just carry a small pump in my back pocket when I ride my bikes that don't have a frame pump.

I still have a few full size Zefal pumps that I carry under the top tube. I use a velcro strap to keep it from falling off, it works fine even on a Tarmac. The velcro straps used to be available everywhere, but I just looked on Bike Tires Direct and thay don's seem to have them. Someone else may, but if not it should be pretty easy to make something though. The originals have a little foam pad that keeps the pump from riding against the frame.

I think any pump you want to use (AKA is good) will be bigger than a bag you want to put on a Parlee. Smallest in my stable is Topeak Race Rocket. Well-made, fits nicely in the jersey pocket, but will not fit in any of my reasonable sized saddle bags. I had a pocket rocket a while ago; that might fit in a saddle bag.

Not sure what's "rattley-bang" about the mounts that go next to a water bottle cage; all of my bikes have a Topeak Road Morph G attached via one of those clips* under the down tube bottle cage, and they are noiseless and don't interfere with my pedaling.


*Edit: Blackburn SK-1, Todson TPD-2C, Topeak TPMB-2C-1, or equivalent... not the stock bracket that comes included with the Road Morph.

this has worked for me without issue for several hundred miles



i sleeved it with a little cut butyl for extra grip and to keep the pump from opening while in the strap.

orucase bag
lezyne pump

the pump comes with a cage mount that i used for thousands of miles and it worked fine and i never once heard it rattle

it is tiny and it's not fun pumping up to 60 psi from 0 but if you're looking to add it as a backup and keep things small, maybe it makes sense for you.

I have never, ever had a mini-pump that was mounted with the bottle cage rattle. Realistically when I had a full frame pump I had way more incidents of that popping loose.

Right now I/we have all of the following:

- 2 different Bontragers, no rattling
- A Lezyne, no rattling
- A Wolf Tooth, no rattling
- My wife has a Specialized one, no rattling
- My son has year another Bontrager one, no rattling

I would just mount it there.

On one of my bikes I have a mini-frame bag and I can put the pump in there with my tools + tube. That works fine too but I don't think it looks right on a racy bike, that's my commuter, and the mini frame bag centralizes the weight towards the front which I think that bike needs. It also gets rid of the saddle bag which could interfere with lights, that bike doesn't have a lot of seatpost showing.

You can also just carry a mini-pump in a jersey pocket, plenty do that. Just don't forget it. For some people it's a bonus that putting the pump + tools in your jersey pocket lets you say your bike is lighter. But it's definitely not any faster uphill.

The bigger issue with mini-pumps is finding one you like that looks good with the color of your frame. Kind of important since most of the time it just sits there and comes along for the ride.

This is the smallest mini pump I know of:
https://www.renehersecycles.com/shop...rbon-minipump/

I wouldn't it as a primary flat fixing device, but as a "I need to get home and I'm out of CO2" pump, it would probably work well enough.

(edit) I don't own one, and haven't used one, but they have been discussed here before.

I’m not recommending the pump as it’s for high volume, but I keep my one up components pump under my bottle cage on both a FS mtb and a gravel bike and I’ve never once heard a peep from either in the years Ive used both.

I had the Barbieri Carbone and it was a pretty good pump but did break on me eventually. I had two of them and they lasted years, and it was back when I had 23c tires and got more flats. It definitely worked. It is weird RH is not listing the brand name, the Nana is also from Barbieri.

I bought the Nana at some point and it broke the first time I used it... it is exceedingly weight weenie to the point it was a liability, unless I got a counterfeit.. but all the packaging looked right.

The problem with both of them is too many carbon parts glued or riveted together to reduce weight. In the case of the Carbone I believe it was the ultralight rivet that failed, in the case of the Nana I must have got one with bad glue.

CO2 is kind of heavy IIRC so even though the pump would be a backup I'm not sure why you'd go weight weenie when you're carrying CO2 *and* a pump. At that point you might as well make sure you have a bombproof pump because you're using it when your primary already failed.

I will go through my mess of mini/micro pumps to see what works. Too bad I threw out most of the thingies used to secure them to bottle cages. I like the idea of frame pumps (what I have on my C50) but as another poster mentioned it would be great if it “fit” (fitment + aesthetics) well.

I like the idea of having something strapped/lashed to a seat bag. That is something I should look into. On one of my bikes I manage to get a small one horizontally into one of the smaller handlebar bags.

My go-to is CO2. Maybe I need to rock with CO2 and one of those rechargeable thingies. Less about weight, more about how compact I can get it. I’ve only had one situation where one CO2 failed to inflate and I was happy I had a second. Of course that made me think “what happened if I flatted again?”. Thus the quest.

On metal bikes, I use a full size frame pump mounted under the top tube. But it is difficult to mount a full size frame pump to a molded carbon fiber frame. So I've been using mini-pumps either strapped to a saddlebag, or inside a saddle bag. Sadly, most mini-pumps are difficult or tedious to use - they either are difficult to hold onto and/or require excessive hand force, or they require many, many strokes to achieve the desired pressure. But after trying many models, I have found a few mini-pumps that are small enough to fit into a saddle bag that are also practical to use.

The smallest saddle bags are usually too small for any practical pump. But a 6"-7" saddlebag can fit a a few some of the smallest practical mini-pumps. The most practical pump I've found that fit in a saddle bag of that size is the Topeak Roadie TT Mini (165mm long). What makes this pump different is that it has a dual pumping acting - it inflates on both the push and pull strokes. That means that it can achieve the same pressure/volume with fewer strokes than a single action pump, and because the pull stroke pre-compresses the air chamber, it takes less force on the push stroke for the same pressure.

If you can find it, SKS makes an even longer saddlebag called the Racer Straps 800. This bag is about 220mm long, but it is fairly narrow so it doesn't look too out of place on a aero bike. This bag can fit even longer pumps. My favorites are other Topeak dual action pumps, including the Roadie TT (at 195mm it has a higher volume than the Roadie TT Mini), and the Roadie DA G (218mm, had a volume half way between the Roadie TT and the Roadie TT Mini, but includes a built-in gauge).

(Note: One of the interesting things about Topeak is they spec the volume of each of their pumps, which can give you an idea of the relative number of strokes to reach the same pressure.)

I've also done what br0qn suggests, and strapped a mini-pump to the outside of a saddle bag. Strapping a pump to the side of the bag might result in some thigh rub, but some bags, like the Castelli Undersaddle XL bag have an elastic sleeve sewn to the underside of the bag that can hold a pump. The Castelli bag attaches to the saddle with a strap that wraps completely around the bag, so you can slide a pump into the elastic sleeve under the bag, and then cinch the strap to hold it more firmly. This allows strapping on a pump that is longer than the bag itself.

I really feel like this isn't nearly the problem it used to be since tire pressures are so much lower.

I don't have anything that goes above 70psi anymore. Flats are rare.

It was those old 700x23c flats that were a mess where you were supposed to be pumping that tire up to 110+ psi that were horrible.

I don't even worry about it on my Farley with the 4.5" tires. I regularly have adjusted the pressure with the Bontrager HV Pro pump. I just got the Wolf tooth 85cc pump and that one also is really easy to pump and moves a good amount of air even on those gargantuan tires. (Helps I target 6psi)
