Hi,
I have a two bottle cage system behind my saddle. This system allows me to screw in two cartridges as well. I strap my spair tube in a small bag underneath.
I have found that I fairly use the double and am just not loving the set up.
I would love a one cage behind the saddle suggestion.
What do you all like? do you have a small bag that you strap to it underneath?
What saddle are you using?
Adamo Racing II
.
What about this from Profile as it seems with that saddle you have a longer distance to reach back.
But this from Xlabs seems like it is the best option.
Zip ties work just fine. My saddle is almost all the way slammed forward so no room on the rails, so I actually drilled two holes at the very back of the saddle itself to run zip ties through it.

Great company, great saddle… one bottle. expensive as all heck but is the only seat that has worked for me for long distance TTing.

for my Adamo, zip ties actually worked better than any 3rd party mount, and seemed more secure.
For integrated bottle mounts, Specialized Sitero works great (I’m selling mine if you’re interested, just dm me). It has oversized oval rails which don’t fit on my new bike’s clamp. I’ve gone with the Dash TT9 now which also has a single bottle mount- seems great so far but I’ve hardly had a chance to use it. But honestly if you like your Adamo, just zip tie a cage using 4 zip ties.
Is this for racing or training? I had the profile design option and it is fine for training. But the cheap sport-top water bottle handups at races do not fit well in there. It is really tough to get one of those bottles jammed back in after you have consumed some of the water.

I guess we also need to know what bike.
Here is a link to a DIY setup that Jesse Thomas used at Wildflower last year, I think he still uses a similar setup. Popular ST zip-tie method with room for atleast a PitStop. I like the rubber band used to keep the bottle in place:
Zip ties. Light and cheap.

This question seems to come up very regularly. I suppose if you don’t need to remove your cage very often (or at all), the zip tie solution is sufficient. I’ve never liked it because I like being able to swap out a one-bottle holder for a two-bottle holder. This is fairly easily achieved with the Tacx unit (which holds one or two cages). Depending on your saddle/seatpost arrangement, it may require a bit of patience with a Dremel tool to get a custom fit, as it did with my Fizik Arione 2/P2 seatpost. I bought two units (they’re cheap), which allows me to switch quickly between a one- or two- bottle setup without relying on (and continuously replacing) zip ties.
If you could wait a couple months we are actually coming out with a new alloy single carrier (very solid & sturdy mount) as well as an aerodynamic storage bag. Aerogeeks talks about the 2 products on their site. The carrier is the Delta 400 and the bag will be called the Aero Pouch 300.
If you wanted an immediate solution the Delta 225 and a mini bag strapped to the bottom of it would work or an X-Strike to carry a couple CO2s.
Top marks for the Aero pouch, clever use of space.
Thanks sharkbait_au! Appreciate the kind remark. Looking forward to getting it out to everyone very shortly

Will that bag be large enough to hold an inner tube?
Zip ties are great. Make sure your cage is tight or you’ll launch that bottle every time.
I also like the Delta series from XLAB. I raced the Delta 300 on my P3 for a while and it was great - much less fuss to set up than my previous zip tie solution (though not quite as tucked away either).
Yes! It looks small, but here is a couple of pictures of the clincher setup. 2 tubes, 2 CO2s, an inflator, 2 tire levers and a tool kit.
