Features:

• The 3 slot base with 4 threaded holes provides additional adjustment 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 zip tie, channels for the zip tie, and a foam pad for secure mounting

Compatibility:

• Mounting any of the bases requires the use of at least 2 standard threaded bottle cage mounts. B-RAD 3 and 4 should use the auxiliary foam pad (to protect your frame) and zip tie to secure the base. Any other mounting methods are not recommended
• You 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 added
• Compatible with any frame that uses standard 64mm spacing bottle cage braze-ons (basically every modern frame)
