Why do triathletes use rear saddle ,mounts for water bottles

Can someone share the reasons why triathletes use rear of the saddle bottle mounts.

Hanging down behind and below the saddle doesn’t seem very stramlined

sports!

It’s also not not streamlined.

as opposed to what? bottles above the saddle? or no bottles back there at all? bottles below the saddle are better than above the saddle, because it’s: 1) hard to hike your leg over those bottles when getting on or off the bike; and 2) if you have a decent position, air is flowing over your back, reconnecting behind you. bottles are going to mess with that.

however, if you’re asking why there are any bottles back there at all, i’m with you. i think there are 2 things pros overwhelming do that are overwhelming ill-thought-out: putting bottles back there at all and putting a cage in between the arms for a standard bottle. a number of hydration strategies are available that are, in my opinion, superior to what many or most of the pros do.

To carry more bottles without having to stick one in a jersey pocket. The TT bikes I’ve owned only had 1 place to mount a bottle cage on the frame. I think it’s fine for training but pointless in a race where you can get a new bottle every 10 miles or so.

Just curious what those options might be? I always thought the best way to carry hydration, in order from the least penalizing to most penalizing, was 1) between the arms, 2) behind the saddle. Or are you referring to frame mounted aero bottles and in-frame hydration storage?

i think that nicely demonstrates my point. both my points. all my points.

Very interesting! I never saw this content from AeroCoach.

Being irrelevant for my TT stuff, it takes a back seat in testing order, but I do own a Trinity integrated hydration system I made work for the TT bike frameset. I can test that against my Fizik Mistica BTS bottle setup someday.

I use the BTS bottle setup to train because I leave the Notio on the bike a lot, and that integrated hydration system would screw the data for TT in the cockpit area.

But, I’m going to bet now the TT bike tests faster WITH the front integrated hydration given it’s like a giant fairing leading into the head tube.

I’m confused-don’t the results suggest a BTA bottle is pretty much the best solution?

What solution do you think is superior (excluding in frame bladders) for a IM race?

I’ve seen some gorgeous triathlon bikes that were turned into bricks by all the hydration and supplies hanging off of them.

Last HIM I did I saw one bike with 5 bottles. Two behind, two on frame and one between arms. Not sure how long they were planning on biking.

Some folks can’t handle on course nutrition, so they need to bring their own. Some prepare for Marshall Law and want to have enough water. Some just don’t understand that it slows them down.

But wow - did you see in the photo how they aggressively hide the BTA bottles in the aerobars? Does anyone actually ride like that? I don’t think any of the IM pros do, just by looking at it.

Was legit very surprised at how fast the aero downtube bottle tested. Am going to get one.

I leave the stock aero bottle on my P-Series at all times. My fitter told me it was more aero that way, glad that someone actually tested that and he was right.

I have not used my rear cage for an actual bottle in years but I do use it as my flat kit and use an aero bottle on seat tube and BTA. Could not get a bottle back there to work without sitting up for a minute and messing around to get the bottle out. Too much hassle.

N=1

Long arms and short torso, so reaching back isnt that hard for me. I race with that as a refill with my preferred hydration for my BTA (Torhans Aero-Z). It is not something I drink from, only a once or twice refill in a 70.3.

For training in FL summers I use that BTS as my third bottle on long rides. I do this for avoiding any spillage in the cockpit, and there’s usually a few hot rides a year where I need that bottle earlier than planned.

Waterbottles between the arms is so 2015. I have a bullet shaped Bluetooth speaker cranking out tunes between my arms now.Fits perfectly in a waterbottle cage and totally weirds out the local geeks on the road here.

Perhaps. And, I’m not the guy carrying 5 bottles but having tried just about every combination available, I can’t totally discount that approach for several reasons
(1) avoid slowing down/ potential crashes near aid stations
(2) easier to avoid missing/dropping bottle at aid station
(3) ensure your have personalized drink mixes.
(4) avoids either refilling BTA with whatever you get at station or trying to fit/keep an aid station hand up bottle into a BTA cage that likely won’t fit tightly.

time savings on behind seat bottle likely lost when reaching back for it…

Some time, definitely. All the time gained, maybe, maybe not. Which is yet another reason I think this subject is so complicated and can’t be determined strictly by referring to wind tunnel results.
