Anyone use the Wolftooth B-Rad system to multiply bottle capacity?

Just looking for a report on whether people on the forum have used this and how it worked. On my 1985 Trek 720, in addition to the seat tube and the inside of the downtube, there are bottle cage bosses on the wheel side of the downtube. I would like to make use of the last, but a full size water bottle sit a bit high, even having switched from 27" to 700C wheels. I would use the B-Rad system to drop the cage by a couple inches, which would give enough clearance for a bottle. I'm also considering using their 2 bottle adapter on both sides of the downtube, which would allow me to carry 5 bottles for this summer's tour.

Yes, I am using it currently and it works quite well. I have had two PDW Lucky Cat cages on my road bike for almost a year now and no real issues. Occasionally I get a touch of foot rub but that is not a fault of the system but me having to run those two cages lower then needed to clear a frame bag.

Pretty much everything from WTC I have used is of great quality and will happily continue using their stuff till they stop making it or if the quality ever goes down.

For the single cage, about a half decade ago I used a short piece of steel bar stock with a few holes drilled in it to lower the below-downtube water bottle cage on a LHT I used to have. That gave me more room for a larger bottle. I was unaware that there was such an adapter available. I also used a piece of double sided velcro to make sure that the bottle did not slip out of place.

In the photo, the bar stock that I added is a bit hard to see, it is directly behind the rear derailleur cable which confuses the photo.

Another option is to use a drill & bit, rivnut (rivet-nut) rivnut tool to add a bottle cage boss higher or lower on the frame tube located the correct distance from existing boss. Cannondale (and other aluminum) bikes used Al rivnuts for bottle bosses for many years. Rivnuts and tool are sold as kit and individually. Bottle bosses typically are brazed on steel frames, but steel rivnut could work too. I suggest using same material rivnut to avoid "dissimilar metal" / galvanic corrosion.

Backpacking-style hydration bladders work too (carried in bag or on rack) for storing and/or dispensing water, several are fitting-compatible with popular water filters, and some convert to showers:

https://www.ortlieb.com/us/water-sack

There's a few oversize bottle cages available which permit carry of large bottles inside main triangle such as Topeak, Minoura and BBB, most now discontinued. There are likely other providers of odd-sized cages of which I am unfamiliar given the proliferation of bike forks with multiple bosses for fitting of such devices. Water can be carried on forks of these bikes, such as newer Surly Troll, Ogre, Bridge Club, etc.

No worries happy to help. I can also highly recommend their chainring bolts, they come in colors and are dual hex so no need for a chainring nut spanner which is a horrible tool that I would love to do away with. Of course on a triple you might not be able to use them quite the same but you can use them as outer bolts if nothing else. Save the nuts for something else.

B-RAD 4, Double Barrel adapter, accessory mount (for saddlebag, since replaced with Wolftooth Roll-Top bag,) two Arundel side-loaders. Only on the bike about 4 months out of the year, but man is it worth it. Usually enough for at least 3 hours on +100º days.

I have a compact frame and my 25oz Podium Chill was too tall in the seat tube cage so I used the b-rad adapter to lower it. Works great and hasn’t had any issues whatsoever. Seems a little pricey for as simple as it is, but it certainly was the most elegant and easy solution. For carrying more than two bottles (or more than one on the MTB) I got a Minoura behind the saddle double cage mount but haven’t had a chance to use it yet.

Good for you, although I was asking about an attachment for a bike, not about a bike for attachments.

I have a couple of these on my MTB conversion to allow 2 * XL bottle cages within the triangle.

Simple idea, very effective.

Or use one liter sized bottles. The one liter sized Smartwater brand bottles fit regular cages, some other brands do too. The smaller Smartwater bottles do NOT fit.

Sorry the photo is somewhat dark.

To clarify

There are many ways of carrying additional water, from using bladders strapped to the back to purchasing one of many ingenious products to rigging imaginative DIYs to building up a frame bristling with braze ons. As indicated in the OP, I'm interested in hearing from folk who make use of the Wolftooth items.

For my fatbike, yes, but not for my touring bike. One of the widgets would allow me to move the cage location down on the underside of the down tube. At present it is high enough that a large bottle rubs the tire (my 1985 Trek 720 was manufactured before the advent of the larger bottles). The second widget would allow for two cages in place of one. A similar arrangement on the inside of the down tube would also double bottle capacity.

If you have room for them in your frame, the 1 liter sized Zefal "Magnum" water bottles are great for touring and fit snugly in any standard cage. I've used them for years. The large Camelbak-style insulated bottles are nice, too, but don't hold as much water relative to their size as the Zefals. They are a bit shorter, though, so may fit where a big Zefal does not (see photo below from my GAP trip this past summer with both types of bottles).

Just curious, do you have leg-rub/strike on the bottles with that setup? Just wondering how wide they splay out IRL. No issues with dumping bottles with side-loaders I take it?

When standing, I will occasionally graze the inside of my calf on the very bottom of the bottles. Impossible to hit 'em when seated, as far as I can tell.

The Arundel side-loaders are pretty grabby. I can't say a bottle coming out would be impossible, but I've never had mine budge.
