The bike I have (fuji women's road) was purchased from performance bike - the motivation was the 30% store credit. Anyhow, I would like to have a cage for a 2nd water bottle. They said they don't drill holes. That it voids the warranty and compromises the integrity of the frame. BUT they sell water bottle holders to attach to the handle bar.

I don't know how comfortable it would be to have the cage on the handlebars, but I am thinking about the kind that attach to behind the saddle, particularly the one that holds 2 bottles vs 1. I do use a medium size saddle bag to hold the spare bike tube, tire repair kit, electrolyte tablets etc.. If I can't attach the saddle bag when having the water cage there, I can either put items in one water bottle or do something else. I generally like to not carry too much in my jersey pockets, preferring the cell phone, one snack, ID. But even for rides that are not very long, I need at least 2 water bottles even with a refill option, because I sweat a lot and the weather here is generally high. I do have the camelback hydration pack, but I have gotten to the point where I am more confident pedaling with one hand on the handlebar and grabbing the water bottle from the cage and putting it back. So if I go on a ride that is not extremely long and can refill, I don't want to wear the hydration pack.

I wanted to see what suggestions everyone has as far as decent water cages for behind the saddle (I would like to use the podium big chill camelbak bottles), or another alternative.

I have seen the carbon fiber regular cages on ebay, particularly from China, with really good prices. I wondered if there are some good deals on the behind the saddle kind.

Thanks!

Monday - here are pictures of my bike. It is the XS or S size which does not include the 2nd cage mount :I

I see small: frame no seat tube bottle cage so the seat post will go in without sawing it short.


1st bike I had , had 2 waterbottles on the handlebar .. this was Long Ago..

Had an AlAn Cyclocross Bike , no bottles because they are unnecessary for a loop course race 1 hour long
I fit a handlebar bottle cage then too..

I bought a Minoura 2 waterbottle cage behind the saddle mount Its well Made.. *

then you pick the cages you want for the bottle of your choice..

+ twofish.biz has Velcro buckle on bottle cages.

* I use the piece to mount my big British saddle bag on non Brooks w saddlebag loop saddles .

big saddle bag can carry more bottles too..

Use a Two Fish Quick Cage Adapter to put it where it belongs on the frame.

FWIW, the linked bike has water bottle braze-ons on both seat and down-tubes. If you have those and there's not enough room you can use a Shimano Dura-Ace Di2 or Sunlite cage relocator to get more clearance. The Di2 adjuster looks better.

I did that when Camelback made the Podium Big Chill cap a fraction of an inch longer so they no longer fit beneath my frame pump in my seat tube cage - one on the seat tube to move that bottle down, one on my down tube to move that one forward and up.

For $11 Tandems East sells a double bottle holder adapter that fits where your bottle holder is now.

I had the same problem with my Trek 7.4 with 17.5" frame. Evidently Trek does not think that riders with short legs have the same hydration requirements with as those with long legs. There was room for two bottle cages but they decided on one mount instead. What I did was drill and install rivnuts on the seat tube and relocate the down tube water bottle slightly higher on the tube using the same rivnuts. I figure if the manufacturer can drill holes why can't I? Yes if the frame has an issue in the place where the holes are drilled I suppose you would be SOL. If the frame fails at a weld or any other place I would not see it as being in issue, If it is they are just looking for excuses not to warranty their defective product. These are what I used https://www.amazon.com/Flat-Aluminum-...uminum+rivnuts

I use a 33 oz Zefal Magnum which may be the largest round bottle available.

There my be some non-round water bottles that are larger.

I got a couple of these. My Raleigh had no bolt holes for a water bottle cage. The description says only two cages but I managed to put three on mine.

Elite Skekane Rear Mount System, Bottles, BOTTLE CAGES

Bluechip

My wifes 43cm Ruby has holes for two cages but the seat tube cage is all but useless. A short bottle is a tight squeeze even with side entry cages. I usually just carry an extra bottle for her. I can carry 5 bottles on my bike.

There are several types of behind the seat holders and some work great and some are bottle ejectors. I've only used an old Minoura that worked well enough. Read reviews and ask in the tri forums.

kba

Thanks to you and everyone else for the replies. I will also post in the tri forum.
rivnuts are a good idea - but I will not go that route in case I do have warranty issues later :I

For the mounts, Minoura, Tandem East are the two mounts which I can put behind the saddle and mount a bottle holder... is that similar to the Elite Skekane Rear Mount System? That looks like an attachment to the saddle, that has the holes which I can nail in the water bottle cages.

I will ask in the tri forum for the brands that don't have the eject or bottle bouncing or falling out problem.

That two fish adapter with velcro, seems like the cheaper quick solution for me to add one bottle cage to the frame or seat post... but I do like the idea of something behind the saddle to have more room for adding a third bottle, or other items I might need.

Be forewarned about some of the saddle rail water bottle cage mounts. They don't fit every saddle. I have had some issues with certain saddles just not having enough room for the mount on the saddle rails.

I have this one currently and it works with my saddle. Amazon.com : Minoura SBH-80 Single Water Bottle Cage Mount for Behind Seat : Bike Water Bottle Cages : Sports & Outdoors
I am using a Specialized Zee cage (right side) and a Purist bottle that I picked up from the shop I got the cage from. It has launched on me before even though it is a tight fit. I figured with the side mount and the bottle fitting well it would be OK and for the most part, it is.

I have tried this mount as well (mounted in the picture) Amazon.com : XLAB Delta Wing 100 Single Rear Bottle Mount System (Black) : Bike Water Bottle Cages : Sports & Outdoors It does not fit most of my saddles and the the one that it did fit somehow broke. The cage that it comes with is also on the heavier side if you are looking at weight factors.

There are a number of options that range from Hillbilly chic to "Wow! I wish I had thought of that!" Two Fish has already been mentioned. Minoura make a similar clamp on holder for the seattube. You could always use a hose clamp (Hillbilly chic). A very nice version of the hose clamp is the Elite Universal cage mount which is a "hose clamp" that doesn't mar the frame like a metal hose clamp can.

I suspect, however that your problem may be due to frame size. The bike you linked to has two cage mounts but your frame may be too small for them. You could mount the bottles behind the saddle but that takes up space that might be needed for other things like a bag for tube and tools. I would suggest looking at mounting the cage under the downtube. It's out of the way but it does get dirty down there. Rinse the bottle before you use it or transfer to the other bottle.

kba

Thanks again for the replies.

I just added 2 pictures of my bike into the first post. Because it is a smaller size, they did not add the second cage mount option :I

I was thinking, if I get the behind the saddle type, to go for one that holds 2 bottles since I would already be spending the money and installing it. But at the same time, don't want to have the water bottle eject or falling out problem.
The brands so far suggested between here and in the tri thread:
xlabs - mostly good reviews but $$ about $50-75 to get one of the wing series that holds 2 bottles. I read a review that said you need the gorilla water bottle holders installed as those are the better ones that done have the eject problem, but those are also expensive
elite skekane - $40 ish - mixed reviews, you put your own bottle holder on it
tacx - mixed reviews, takes work $23, can hold 2 bottles
Minoura - $16, can attach 2 cages, Generally OK reviews, some saying they have had bottles fall or fly out.
Profile Design - RML $50 already has 2 cages on it, reviews OK

For the option of clamping under the tube (where non-small bikes do have a water cage mount)
Two Fish - $17 generally good reviews
Elite Universal cage mount - $11 - mixed reviews
Hose Clamp $1.50 for each, and in the tri thread, suggestion using electrical tape to protect the finish on the bike when using these

Maybe I can go ahead with the hose clamp idea for now since it seems to do the job. Then whichever of the saddle options (based on feedback) have the least chance of bottle ejection, get the one out of those that costs the least.

fietsbob

the Minoura one does not include bottle cages , so any bottles flying out problem

is an issue of the bottle cages the buyer chose , not the bracket they attached them to..

kba

Oh I see! That helps me narrow down to Minoura since it is $16. What cages would you recommend that does not have the flying out problem that does not cost $50-60 like the xlabs gorilla??

Bluechip

Sometimes it's the angle that the holder puts the cages. I was mistaken when I said I had a Minoura, it's a Trimble.

fietsbob

Ones that are also resistant to putting the bottle in, so lock them in the cage.

I have this on my rear of my bike friday seat post mount. https://www.universalcycles.com/shop...2&category=272

You can get tool tubes that fit in a bottle cage. So if you put two bottle cages behind your saddle, one can hold your wedge stuff.

Retro Grouch 

That's a pretty small bike frame. I don't think that you are going to be able to install any kind of water bottle cage on the seat tube. It looks to me like it will either hit your down tube mounted cage or else be so high as to interfere with the top tube.

fietsbob

One option is a side release bottle cage .. You would be advised to stop when you switch your empty convenient bottle
and your Full inconvenient placed bottle .

There is also an under the downtube bottle placement you can utilize. Touring bikes have that.

CliffordK

Is there room for a seattube cage behind the downtube cage?

How likely are you going to have to return the bike for FRAME warranty repairs? Wheels, tires, bottom bracket & etc should be completely independent from the frame.

You should be able to argue that even if there is a frame warranty claim, that anything independent from your cage mod would be unaffected by that. So, mounting a cage on the seattube would have nothing to do with a fork or rear triangle failure.

Installing rivnuts should be a pretty simple procedure if one can get the tools in the right spot.

TenSpeedV2

You could try these right on the seatpost to at least carry an extra bottle.



Have you considered using a Camelbak or similar hydration system?

kba

In theory I see how it should not matter. I am not always successful in debating with warranty people..

I think the Minoura would fit on the back of the saddle, then I can attach 1-2 cages on it.

Where did you find those clamps? I have a 1.5L camelback. IT works well for me, but as my confidence in pedaling with one hand is better, and for shorter rides where I need less, I wanted the option of the extra water bottle.

I like these options, the second one is on Amazon for $6 (As part of the add on program). I also see this Topeak adjustable one for $6

fietsbob

I have one that Blackburn made decade+ ago; takes 2L store-bought bottles of water.

CliffordK

Of course, years ago, all the cages just had a strap holding the to the bike. Not fancy, but easily adjustable.

Unfortunately, with all the OS tubes, the technology hasn't been supported. Nonetheless, one could probably make one's own straps.

TenSpeedV2

I first saw those when I bought my 2010 Specialized Stumpjumper FSR full suspension mountain bike. The way the suspension set up was, there was only room for one bottle. They came with the bike so that you could just clamp them right to the seatpost if you wanted to run a second bottle. I forgot about them even after reading this thread. You would simply need to find out the size of your seatpost and see if you could get these. It was a solid setup when I tried it. You simply mount the cage to the clamps, and then tighten the clamps to the post so that they are the proper distance. Once you have that, you can change the cage out whenever you need or take it off if it is not needed.
