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.Nifty solution for customizing storage of your bike frameMounting Base is the first required step of the B-RAD systemAvailable in two, three, or four slot versions for custom fitAdditional Bottle Mounts and Accessory Straps sold separatelyGreat for full-suspension and small frames with tight clearancesAttaches directly to 64 millimeter bottle cage braze-onsIncludes mounting brackets and stainless steel hardwareSupport pad with zip ties included (B-RAD 3 and 4 only)Material[brackets] 6061-T6 aluminum, [hardware] stainless steel, [support pad] neoprene, zip ties (B-RAD 2 and 3 only)Mountcompatible with 64mm bottle cage braze-ons (virtually every modern frame)Activitycommuting, enduro, gravel, trailManufacturer Warranty1 year
