Your cart is empty.Designed to attach to Wolf Tooth's B-RAD Mounting Base, the B-RAD Double Bottle Cage Adapter holds two water bottles side-by-side so we can stay hydrated on longer hauls and trail rides. As a nifty alternative, the B-RAD Double Bottle Cage Adapter can attach one water bottle alongside a Mini Strap and Accessory Mount (sold separately) for greater storage of tools and tubes in remote riding locales.

Fit perfectly on my Santa Cruz hightower now I have the ability to carry more water for my really long rides. It was also very easy to install, feels like solid quality material, and doesn't move at all.

I've been getting into bikepacking and I need to carry a lot of water. With this, I can carry 3.4 liters of water on the frame among the seat tube and top and bottom of the down tube. The instructions say you must use the B-RAD mounting base (sold separately) but I bolted these directly to the frame and they hold two bottle cages really well - I don't think you really need the mounting base, unless you want to slide the bottles up or down to avoid conflicts. It is annoying they use star drive for the cage mount bolts but I went to the hardware store and found standard Allen bolts for mounting the cages to the adapters. I use these on top of the down tube and you might be able to mount these in other locations - especially if you used the B-RAD mounting base to change positioning - but just be mindful of your cranks or legs conflicting with the bottles.

Part is perfect exactly what you would think for the price but what I want to highlight more is the amazing service from the bike shop. Had some shipping issues and shop handled it to the highest level of customer service I cloud have experienced. Thanks guys

Product was great. Customer service was great. My only concern was how the cost added up from separate components. Still, very satisfied after months of use.

Absolutely love this. My MTB holds one bottle natively. I hate riding with a camelback in races, and wanted to find a system to hold two bottles and this works perfectly. You have some play with the B-RAD system as to how high this can go. I put it as high as I could (22 oz bottles) and it tucks in neatly. I have found that it almost never interferes with my legs. Sometimes if I am climbing, am out of the saddle and am forward on the bike (which is all bad form), my knees are "aware" of it, but I have never bumped into it. I would recommend paring this with bike cages that you can pull a bottle off from the side (instead of from the top.)

This is the bomb. I have it a full suspension mountain bike, a hardtail mountain bike, and my road bike. For the fully bikes this makes a second water bottle possible at all, which is great because I'd prefer to not carry a hydration pack. For the hardtail this allows me to use the cage on the seat tube to hold a little plastic can with tools in it. On my road bike it allows me to carry three water bottles, which is really really nice on 60-mile rides and whatnot. There comes a point where you just can't carry enough water, but when I'm road biking I always pass a bunch of places where I can go in and refill. Having three bottles ensures I'm not doing that every half hour.

Using them on a fat bike with only one bottle cage holder on the down tube. This allows me to place two water bottles side by side. They do not interfere with the crank arms. I'm using it with a B-RAD mounting base that allows me to position the bottle where it's easiest to reach but low for good center of gravity. Highly Recommended if you want to carry a second water bottle.

タイトルの通りです。如何せん高いです。1000円以下なら文句ないんですけども・・・。あと、・素材がアルミなので重たいツールケースやドリンクボトルを2個付けると金属疲労が怖い・ボルトがトルクスで面倒くさい・ボルトが短いというのもあります。

グラベルバイクにフレームバック追加したらボトルが取りにくくなったのでB-RAD4とともに購入少し横にずらすだけでとてもボトルが取りやすくなりました

ロングライドする際にボトルを２本持って行きたくて、ただ一つはツールボトルが占領しているので、増設する為に購入。ライドに邪魔にならない位置にする為に同B-RADのマウンティングベースで位置を上にあげつつ設置した。結構便利。ただ個人的な好みで２本並んでいるとみた感じがゴタゴタして好みではないので、ロングライドで必要な時以外で外している。
