Lowering Down Tube Mounts

Why are the two water bottle mounts for the down tube so high.
Why aren't there multiple mount points along the length of the down/seat tubes.
Does an adapter widget exist that fastens to the existing mount points that effectively offers lower, or adjustable, mount points along the tube?
Those first two questions are mostly rhetorical.

Less than ideal bottle placement:



Preferred bottle placement:


Every bike frame should look like this:

"mounts" for what, exactly?

Shifters?
Water bottle cages?
Cable stops?
mud guards for your Playa-bike?
three toed sloths?

Edit: thank you for now updating your post with specific complaint info.

if you are talking about brazed on shift lever mounts on a road bike downtube - wouldn't it look dumb to have 3 or 4 pairs of them, with only one set used ?

Also remember that as you down the downtube, the tubing guage is thinner due to butting and better not to braze there because of heat

if you have clamp on shift levers, feel free to put them anywhere ! Below the waterbottle mounts, if that works for you

If you are talking about the mounts for the bottle cage to screw in, then it's because they have to put them higher so the bottle and cage on the seat tube has room. Some bikes have pretty short seat tubes.


Many of us would just find a clamp to go around the tube to hold on what ever we need or install a riv-nut. If it's a steel frame, you can have someone braze more bottle bosses or other mounts on it. But then you likely would want to paint it to cover up the burnt paint.

If your paint is nice, I'd put a piece of vinyl on the backside of the mounting base.

You could acquire a new bike that has more brazed fittings than you know what to do with.

If you are talking water bottle cage bosses, you can use something like these to raise or lower the cage position:

The type on the left is nicer in my opinion and if you go the Ebay route, don't cost that much (the one pictured is a Wolf Creek one, which I have on one of my bikes but I also have the cheap kind on another and it works fine).

I presume you mean the mount for...downtube shifters? If so, they are located where they are due to the proximity to the handlebar. How far do you want to reach to effect a shift?

Does an adaptor exist? Yes. Find one of the band-clamp style ones common on vintage bicycles. You can mount it anywhere on a tube of the proper diameter. Near the seat stay cluster is common & popular on Rinko bikes.

I used to think that providing every conceivable fitting would make for a nicer build with no extraneous bracketry, but then I saw a frame like that and realised that I wasn't willing to tolerate the appearance, regardless of its potential utility.

I have had a ream of 50/51cm road bikes, and it never ceases to amaze me how some companies get the bottle placement right and so many are meh.

It is an overlooked art.

The mounts look to be as they should be, you move the downtube bosses then you can't fit the second bottle cage on seatube. Gosh maybe the down tube bosses are way to high and the seatube bosses are way to low. Boy those engineers at trek are drunk mofos.

Your jug is not meant for your cage. Lol

So...exactly how are you going to fit the second bottle cage? Answer: You aren't. The bottle mounts are perfect as is, and your solution has eliminated the option for a second bottle.

Looks like ideal bottle cage bolt placement - for use with bicycle water bottles, not soup containers.

You'll note that the downtube position leaves just enough room to put another bottle and cage on the seat tube, and that cage is low enough to let the bottle sit under the top tube.

Neither of the cage mounts are for random containers, batteries, art installations, etc. That green thing looks like it will easily fall out. You're trying to use the wrong kind of cage to hold that thing. They do make special cages for stuff like that, and those cages probably sit lower as well:

As Lincoln might have said, "You can please some of the people all the time, or all some people all the time, but you can't please all people all the time".

To answer the OP's first question, the DT bosses are forward to clear a bottle mounted on the seat tube.

The simple fact is that it's,hard to squeeze 2 bottles onto a small frame. Also, mist people like DT bottles forward, so they don't have to reach down so far.

My suggestion is to use 2 n smaller bottles rather than one tall one.

For your consideration, I wouldn't want to have to reach down so far to grab the bottle unless you feel it's just not fitting in the space it's at right now (looks fine to me, but maybe you're fighting too much to get it around the top tube?).

Well you also have to consider the pics the OP added to the post later after I'd replied. They show a tall water bottle with not much room to the top tube. So using the mount adapter that was shown by another might solve their issue and still have the top of the bottle at a decent height to grab.

However I would just use two shorter bottles with one on the seat tube. Probably that would let me carry more water than just one tall bottle. And give me a choice of water in one and some favorite hydration mix in the other.

But thanks for your endorsement!

You seem like a candidate for the side-loading bottle cage that Velo Orange offers -- keeping the top of the bottle in easy reach while allowing pulling the bottle out without fouling the top tube: CAGE

I think it was pretty obvious and two posters here have already answered, but if you lower the downtube water bottle mount, there is no room for the seat tube water bottle.

Many gravel bikes now have at least 4 or 5 mounts for water bottles.

I really don't know why folks keep trying to use non-cycling bottles like "MotivationalSports Water Bottles with Time Marker & Fruit Strainer", and then expect them to work along with cycling bottle cages in properly designed cycling bottle cage mounts.

Another thing to consider is getting a side-load bottle cage where the bottle goes in from the side. That way you don't need as much clearance to pull the bottle out and could leave the bottle where it is and allow for a bottle on the seat tube.

I cracked up when I saw “motivational” and then realised it actually has messages printed on the side. Extraordinary. “Way to go! You’ve spent half the working day in the toilet”

I've heard them called barnacles. Touring bikes really can't have enough of them, especially on the front forks.

BTW you can easily add more rivnuts to that aluminum frame, but the other solutions of offset bottle mounts are the better option
