looking at options for storing tools / Co2 on bike. Any recomendations?  bottle cage / bag / other? thanks
Back pocket, bumbag or bag - on bike just gets everything clarity or bits seem to rattle a bit.
Obviously no help at all, but on bike solutions seem to be a compromise of something to me. Either tools are very small, never clean, rattle a bit, or frame gets rubbed by mounting solution when it gets manky or it can be a faff of sorts to retrieve.
The one-up pump solution looks neat - seems to have a pump and toolkit inside - no idea how it works, but it looks good. Unsure how small the tools are though and also no idea how good the pump is. If I was keen, I'd be carrying that in a pocket rather than on the bike.
Ive got the one up tool stash and really like it, however if you want the co2 storage I'm sure you have to have the screw in version. The one I have has a multi tool, levers, somewhere for a chain link and some bacon strips.Â

As DickBarton says, things on your bike will get covered in grime; even if you're talking about a road bike you'll get a fine layer of grit/ salt on everything, plus possibly rust.Â
On the road, I've always used a combination of saddle bag and top tube bag, with a minipump attached to a bottle cage
Hip pack on the MTB, small top tube bag on the gravel bike. Those pocket tool rolls are useful for stopping rattles in bags I find.
giant clutch system
multi tool in crank
tyre plugs and knife in bar ends
co2 and inflator in lower fork steererÂ
Despite having downtime storage in one bike - complete with two padded tool rolls that came with the bike - I still carry everything in a small backpack (or bigger EVOC bag). With multiple bikes I don't want to have multiple sets of tools/spares. Inevitably I know I'd forget to transfer it to the bike I take out, and that'd be ride when the mechanicals happen...
I have a lezyne flow bottle cage with a mini pump strapped on instead of CO2 and a quick link instead of the CO2 head, the multi tool is pretty comprehensive and has a few tubeless worms, If Im going far I strap a spare tube in a piggy on too
I also have a Camelbak podium flow bum bag which is just enough for all my kit for longer rides
Â
I have the One Up pump and I transfer it between bikes. Works well for me. Yes it gets mucky but I don’t always want to wear a pack.
Mine has the bacon jabber, quick link pliers and a spare valve core.
No need for CO2.
 It’s not that light but then neither are any of my bikes.
+1 for the oneup pump - the small one goes in my back pocket and has everything I need
Â
On my mountainbike I have the same in my steerer tube but the pump is better
Another +1 on the small one up pump with the tools in the handle. Swap between bikes then you don't have to buy multiples of everything. Spare tube strapped to the bike
For short local rides that means I can go packless with just water bottle on the frame.and phone/keys in pocket.
For longer rides I carry a few spares (e.g. brake pads, spare tubeless repair strips etc) in a tool wrap under my saddle, also a pair of pliers / knife in bum bag.Â
Enough to keep you rolling in almost all breakdown situations and keeps the vast majority of the weight on the bike.and off you.
I have the OneUp steerer tool and the pump, steerer tool is generally for MTB and pump for road/gravel as you can't tap a thread into a carbon steerer tube.
It's not cheap but it's very well made and really useful, having tools right in front of you is really handy and they're well well protected from mud etc. I have a few frame and saddle bags that just get covered in crap.
I'd thoroughly recommend it, I think it's worth every penny (especially if you wait for one of their sales).
If there is space a frame bag is great. You can access it whilst riding. It has plenty of space. It’s relatively protected from crud.

But my FS bike is still using a hydration pack
The one-up pump solution looks neat - seems to have a pump and toolkit inside - no idea how it works, but it looks good. Unsure how small the tools are though and also no idea how good the pump is. If I was keen, I'd be carrying that in a pocket rather than on the bike.
Another happy owner. I carry in it a bum-bag rather than on the bike - that way it moves between mountain bikes with me. I don't use the cage mount for it, mostly because I have an irrational fear that I'll somehow lose the thing and it seems like a lot of money to leave lying about on the floor. Plus carrying it off the bike means it's clean rather than encrusted in Peak grit.Â
As a pump I've found it really effective. The tools are decent too. Haven't used the steerer mount, but the tool is the same, I think. I'm quite happy with an Osprey bum-bag/lumbar pack on the mountain bike, doesn't interfere with my riding and means I can carry a small first aid kit, spare lightweight clothing, snacks etc with minimal hassle.Â
On the gravel bike I use a small Lezyne saddle pack for tools and tubes, plus keep food, phone etc in a Tailfin top-tube bag, which means I don't need to use a pocketed jersey.Â
