Interesting that they make a point of stating this.
And so they should. Rivnuts on a high end frame is just lazyass cheapness in the extreme.

There's a design fault with most water bottle cages.

It's the leverage caused by having only two bolts raised above a thin frame tube that's the problem.
Not in my experience. One dead seatstay rivnut on my Ragley Rodwell, bottle bosses still intact despite regular abuse: Tour of Flanders, a couple of HONCs, London to Paris off road, etc (although they may not be long for the world if they're as badly manufactured as the seatstay mounts).

Aye, plus weaker and not just for the bottle. A welded/brazed boss ends up with a reinforced 5mm hole in the tube. A rivnut ends up with an 8mm hole, stressed by having the nut clamped through it.
I avoid using the things unless absolutely necessary.

Is that adjustable (up and down) bottle cage one you can buy? Any chance of a web link?
Or is it home made?It's Photoshop made
I did make one out of a bit of Meccano or something similar.Posted 12 months ago # -
making it less stable and putting the rivnuts under a side load.
And this matters because.....?

All the steel frames I've had stripped and PC'd have had the bottle mounts brazed in?
Of my alloy frames my old merrida was welded IIRC, the cannondales were rivited (and one had issues), I haven't looked at the Pitch (but suspect as they're owned by merrida that they're welded too).
The design flaw seems to be the rivinuts then, not the bottle holders? Anyone had any problems with welded/brazed bottle mounts?
who uses bottle cages anyway? Its all Camelback round here
Get back to MBR, we're far too niche here.On a serious note I stopped using camelpacks for shorter rides, and bought a 1.5l one for winter rides as it'll hold about 750ml of fluid + battery and the usual contents of my jersey pockets. The big propper one still comes out for longer rides.

My Dakine back pack fits perfectly. And much better than a bottle cage.

I thought bottle cages on mtb's were for light batteries.
Do people only ride with bottles?
If you do where do you put all the rest of the stuff?Posted 12 months ago # -
erm?? wouldn't a brace between frame and cage make more sense. Protect the frame, reduce vibration and help spread load. Nothing worse than bottle cage wobble noise.

mtg, I think you're an engineer ( are you actually an Engineer?) looking for a solution to a problem that doesn't exist in the real world...

Jersey pockets (CO2, tool, patches, gel and a gillet)
Spare tube and spare brake pads taped to the frame/seatpost (makes having the right one easier too, rather than a backpack full of 26/29" tubes)
Quick links inside the brake levers (same logic as above with, 9s, 10s SS bikes)
This does rely on you not following the MBR/MBUK trend for wearing DH jerseys for XC though.

Spare parts ,shocked with people taking spare pads
Does no one give there bike a quick check before taking it outAm I not going long snuff runs ,never worn a set of pads out on a run.
Sticky patch and a co2 and bank card for breakfast water bottle that's it
Nine times out of ten I forget the patchPS my giant and the missus felt are both welded bottle bosses

I would prefer there to be clearance between the bottle cage and the frame as it is easy for dirt to get trapped in there and the thing will flex and move around with the weight of a bottle of water so there is a high risk of abrasion damage to the frame - regardless of the material. Also clearance gives the opportunity to have pump mounts. If anyone has a cage that contacts or comes very close to contacting the frame then put some protection tape on the frame where it could rub.
