B-RAD Mounting Base

Wolf Tooth Component's B-RAD Mounting Base provides an ingenious solution for trail riders, gravel seekers, and urban commuters seeking on-frame storage for water bottles, spare tubes, and accessories. The Mounting Base is the first step required before attaching Wolf Tooth's separately available Accessory Mounts and Bottle Adapters. It's available in either two, three, or four slot versions for customizing the storage potential of your frame.

We think it's a great idea, especially for smaller frames and full-suspension machines where clearance is limited, normally forcing you to adopt non-traditional methods of attaching a water bottle, like on the underside of your downtube. These other methods of bottle attachment often lead to awkward placement and aren't exactly the most aesthetically pleasing. Realizing this, Wolf Tooth created the B-RAD system to shift the location of water bottles and storage straps out of the way, so they don't come into contact with your piggyback shocks or tight frame clearances.

The B-RAD Mounting Base attaches to virtually any modern bike, so long as it uses a standard 64-millimeter bottle cage braze-on. To find out which version is best for your specific bike and riding application, Wolf Tooth provides a printable 1:1 document that can be cut out and placed over your bike frame.

Details, Details ....

I've put it through the wringer

My Faithful Steed™ is almost perfect. Almost. For, you see, the seat tube bottle bosses are located almost midway up the seat tube, making bottle fitting difficult on this small-ish frame. Cannot fit a full-size bottle in the cage. What to do? Enter, stage left: Wolf Tooth Components B-RAD mounting base! Installation was quick and easy, let me shift the bottle cage location downward (where it's located on the newer Colnago's). A full-size 24-ounce bidon now slips in without interference. Bravo, Wolf Tooth!

perfect to move my bottle cage up

I've used it several times

had little room in my frame for a bottle cage when using the manufacturers bottle cage mounts. This gave me the flexibility to install my bottle cage so it did not interfere with the rear shock. sweet! Be aware though, you'll need a T25 torx driver to install it with included fasteners!

Make Space

I've used it several times

I purchased the 2-slot variant to accommodate bottle cages as well as my frame bag. The mounting system is easy to work with and is not susceptible to the rattle the 4-slot base has. If you need just a few more inches of space in your front triangle, the B-Rad system will work for you.

It gets the job done

It does extend your bike capabilities, but larger versions doesn't look good, and shorter version doesn't really add much extension points. I ended up buying all sizes, but none of them make me feel happy.

I went with the four slot to have a few more options on my fat bike for bikepacking. The materials and hardware are high quality, yet simple. The longer the length you use, you may need to use zip ties (included) to ensure a rattle free and secure mounting. Other than that, I have no complaints with what it does.
