B-RAD 4
-The 4 slot base is the longest base with 9 threaded holes for the ultimate flexibility and capacity when bike packing, touring, commuting or just exploring on 2 wheels. It′s long enough to mount 2 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 mounting
-B-RAD 4 base instructions

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)
