B-RAD Bases are the foundation for the B-RAD system, as the rest of the system accessories mount to them. These allow you to move bottles to make room for frame bags, move bottles away from suspension shocks, create space to mount additional bottles and/or bags to the same bottle mount.Repositioning uses existing bottle mounts on frameLightweight, durable, rust-proof materialsCustomize storage to your specific needs with flexible B-RAD systemB-RAD 2The 2-slot base can move a bottle or other accessory up to 54mm to an optimal location even on a smaller or dual suspension frameB-RAD 2 base instructionsB-RAD 3The 3-slot base with 4 threaded holes provides additional adjustment of up to 118mm and mounting options vs the B-RAD 2. A typical application would be to mount a bottle cage in the forward threaded holes with a B-RAD accessory tucked behind it. This mounts perfectly to triple bottle mounts on frames and forks. The B-RAD 3 includes a recommended zip tie, channels for the zip tie, and a foam pad for secure mountingB-RAD 3 base instructionsB-RAD 4The 4-slot base is the longest base, with 9 threaded holes for the ultimate flexibility and capacity when bikepacking, touring, commuting or just exploring on two wheels. It′s long enough to move one bottle up to 201mm, or mount two small bottles inline, or multiple accessories. The B-RAD 4 includes the required zip ties, channels for the zip ties, and a foam pad for secure mountingB-RAD 4 base instructionsDOGBONEThe Dogbone can be used to offset a bottle or other accessory to an optimal location. Most commonly used for smaller, curved, or dual suspension framesDogbone base instructionsCOMPATIBILITYMounting any of the bases requires the use of at least two standard threaded bottle cage mounts. B-RAD 3 and B-RAD 4 should use the auxiliary foam pad (to protect your frame) and zip tie to secure the base. Any other mounting methods are not recommendedYou may need a Problem Solvers Space Out Kit or similar method to clear the front derailleur clamp. Be sure to use bolts with additional length equivalent to the extra spacing addedCompatible with any frame that uses standard 64mm spacing bottle cage braze-ons (basically every modern frame)Hardware included is T25 Torx headSPECIFICATIONSWeight: B-RAD 2 • 27g | B-RAD 3 • 41g | B-RAD 4 • 75g | Dogbone • 10gMaterial: 6061-T6 aluminum brackets | EVA foam padThickness: 6 mmTools Needed: T25 TorxTorque: 3-4 NmMax Load: 1700g per baseMade in the USA The StoryWolf Tooth was founded to design and manufacture precision cycling products that emphasize function, performance, and reliability to meet the needs of our fellow racers and riders.We are a group of cyclists in Minneapolis, Minnesota that spend a lot of time talking about bike components.
