Rear bottles ejecting

Brad Marcus

As HIM #1 of my season is less than a week away, I have been riding over the last week or two with race wheels on. They are significantly stiffer than training wheels. My hydration setup includes 2 cages on an xlab sonic rear wing behind the saddle. Every time I hit a significant bump in the road 1 or both bottles are getting ejected from behind. In fact, I raced an Oly a week ago and in mile 1 I lost a bottle this way.

I am somewhat concerned about this when racing Vineman next Sunday. Any tricks or suggestions put there to prevent this from happening?

Have you tried the Gorilla Cages? I use them on my rear carrier during training rides and have never had a bottle eject...even when going over train tracks.

Second for Gorilla Cages. I haven't had any ejections from behind the seat. I do, however, have the bottle cages set up in the most upright position.

In addition to the gorrilla cages -- I believe Xlab recommends the Specialized Purist bottles -- the past year I have been using the combination and have never had a bottle eject even cobblestone like roads (full or empty)

I don't run bottles behind the seat anymore but when I did I used the attached process to modify two plastic cages, worked a treat!

I have been losing bottles for ever on my P2, with gorilla cages and all kinds of bottles. Lately switched to the Specialized bottles, supposedly impossible to eject. Took about 2 minutes before the first one was gone. BUT!!! Then got some Specialized Rib Cage cages and those restored my belief in humanity! Never lost a bottle since, and been riding on rough roads a lot. Finally, problem solved.

I don't know what people find so awesome about gorilla cages, I think they suck. Rib cage = 1000x better in my experience (also much cheaper!).

I don't know about Rib cages but will look into them ( as they are much cheaper ) LIKE ! I too use Gorilla cages with my Xlab and they solved that problem for me as well.

I rode with a Rib Cage until just recently when I broke it at the Lake Placid training camp. Never ejected a bottle from it.

The break happened in front of the Ski Jumps at about 36 mph going thru a pothole that must have been 16" across and 5" deep. Dam near knocked my teeth out! Despite both side ribs snapping, my full 26 oz bottle never launched. I didn't even know it was broken till I got back for resupply. I added a zip-tie and some velcro and was off for my second lap.

gorilla cages here, too

Multiple LARGE rubber bands on the bottom of the bottles significantly reduces the ejections for me. Still launch one now and then but not nearly as often. Pretty cheap solution for a 98% fix.

Do you keep your bottles in the fridge overnight? For me, stopping doing that reduced my launch rate to near zero.
