Has anyone mounted a cage directly to an aero seat post?
I’ve been thinking about putting a flat kit together in a bottle/cannister, and mounting a cage so I can tuck it right under the back of my seat. The problem is the pointy back end of the aero seatpost. Zip ties don’t hold tight, no bracket I know of mounts tight to the seatpost…
So DIYers, any ideas? Anyone else try this? Do any brackets exist that mount tight?
Looking forward to the ideas. Thanks.
I didn’t mount mine right to an aero seatpost, but I did mount a very small bracket directly to the rear to the seat and then mounted the cage to the small bracket. The bracket was an old “Specialized” behind the seat bracket. I drilled it directly into the plastic in the rear of a Vision Tech seat. It held for years and through the selling of that bike. It kept the single bottle very secure, up high and close to my butt.
There’s a product just for doing this. I’m googling “as we speak”.
Found it:
Arundel Tri Clamp:

I know about the Arundel. It is a mount for 2 bottles, and is a little long for mounting directly under the seat. But it is as close as I can find too. I’ve been thinking of carving up a hockey puck with the V-shaped notch, and adding some velcro straps. I’m not overly handy though, and the thought of carving up a puck scares me. I was hoping for some magic hardware piece from Home Depot…

Have you tried putting a couple layers of cut up inner tube under the zip ties? Might give some extra grip. Also, instead of a hockey puck, how about a piece of oak painted black and then the cage bolted into the oak?
Hey, I like the inner tube idea. I’ll give that a try.
I did think about wood, but worried about it splitting. A vulcanized rubber block seemed sturdy.
Thanks for the ideas!
BTW - someone on ST had a bonty aero bottle mounted behind the seat. I can’t find the picture, but I think it would provide some ideas too.
I just lash the bottle under the seat with a velcro strap (used for organizing electrical cables…available at any Target or Home Depot).
Here’s the flat kit inside the bottle:

Have you looked at the Tacx? It mounts to the saddle rails close to the seat, highly adjustable, and can mount 1 or 2 bottles. Fairly cheap too.

Works perfect…though i really dont like the idea of rear cages I have to use one as my frame only takes one cage and an aero drink hits my front tire. two zip ties on each rail and one in the center through the fizik clip. never ejected a bottle and quite minimalist.
If it’s to hold a flat kit the bottle could be glued or otherwise secured in to the cage.
Might not be a bad idea for safety.

Have you heard of saddle bags?
Available at any bike shop!

X2…I was gonna say the same thing. The bag is much smaller, formable to nearly any shape, doesn’t rattle, and tucks up under the seat perfectly and very aero. Everything you have pictured fits totally in the bag.
Same here… if you actually want the option of carrying a drink bottle that’s one thing, but if you’re just gonna use it for a dedicated flat kit, then the saddle bag is hard to beat; more secure and no rattling on rough pavement. I’ve done it both ways… cage when I want extra fluids on longer training rides (flat kit & tools in jersey pockets) and then swap it out for a small seat bag for races. The back “fin” part of the P2C/P3C seatpost gets in the way, but I just use a couple zip ties as an extension to loop the straps to the rails.

There are many good reasons to go with the bottle option vs. a saddle bag:
-Waterproof
-Less expensive
-Moves easily from bike to bike
-Easy to remove for bike races
-Fits into the rear bottle mounts on my tri bike
-Easy to toss to a racer who is stranded (done this twice in races)
-Won’t swing/bounce
Like most, I started with a saddle bag. I really like the bottle option, IMO it works much better…I will gladly send the OP my old saddle bag if he wants to go that way (PM me).
Titanflexr: What pump is that? Can it pump up to 110? I am tired of CO2’s.
It’s a Blackburn AirStick SL ( http://www.become.com/blackburn-pump-Blackburn-Air-Stik-SL-Bike-Pump?&qet )
It’ll get to >110psi, but it takes about a billion strokes (ok, more like 300). In reality, this is for getting me home, or to T2; I usually pump to about 85-90psi and hit diminishing returns. I only flat about 1X/year, so I’ll trade off the small size for ease of use (when in a group, use someone’s full size frame pump). The other benefit is that it won’t misfire or run out like CO2s. It’s slower, but I figure that if I flat my race is over regardless of whether I lose 5 minutes or 8.

Amazon has the white version on sale for $11.38.
I use the tacx but the way johnnyo does it and the tacx I screw through the 1 hole on the seatpost
if you do a search for it or I can just to find the post
THe bottle sit basically right underneath my saddle
.
We’ll agree to disagree…
Everything you mentioned holds true for a bag, too.
I can see no reason to use a bottle for a tool kit. Its too big, bulky, noisy…
Besides…I’ve never carried any tools in a race. I carry a spare kit in training, sometimes, when my wife is not at home to be able to call if I have problems. A cell phone makes a great tool kit : )
