Wolf Tooth B-RAD Mounting Base — Short 2-Hole Adapter, Anodized 6061-T6 Aluminium, 1700g Load

Wolf Tooth's B-RAD Mounting Base is a shorter, two-hole adapter that repositions a bottle cage for better fit on small frames and full-suspension bikes.

The B-RAD Mounting Base is the shortened component of Wolf Tooth's B-RAD 2-slot system, crafted to shift your bottle cage location without changing cages or frame modification. Made from 6061-T6 aluminum and anodized to match other Wolf Tooth hardware, this adapter gives you a secure, lightweight way to mount hydration where standard bosses won't allow it. Torque specifications and load limits ensure safe use when paired with compatible bolts and cages.

How does the B-RAD Mounting Base help on small frames and full-suspension bikes?

Small frames and bikes with rear suspension often crowd the space where a bottle cage would normally sit. The B-RAD base shortens the distance between the frame bosses and the cage, moving the bottle inward or upward to clear shocks, linkage, or kicked heels. It preserves bottle access and security without permanent changes to the frame.

• Shorter bracket profile reduces interference with rear shocks and suspension pivots.
• Two threaded mounting holes allow precise fore-aft or up-down adjustment.
• Anodized finish matches existing Wolf Tooth components for a cohesive look.

What are the materials, strength limits, and installation details?

The Mounting Base is machined from 6061-T6 aluminum for a balance of weight and stiffness, and anodized for corrosion resistance and visual match. Wolf Tooth specifies a 3–4 Nm torque range for the mounting bolts to secure the base without overstressing the threads. Maximum static load per base is rated at 1700 g — adequate for standard water bottles and many multi-tool or pump mounts if used within that limit.

• Material: 6061-T6 aluminum for lightness and durability.
• Torque: tighten bolts to 3–4 Nm to avoid stripping.
• Max load: 1700 g per base; do not exceed rated weight.

Will the B-RAD Mounting Base work with my bottle cage and frame hardware?

The adapter was designed to integrate with the B-RAD 2-slot system and standard two-bolt bottle cages, so compatibility is broad but not universal. It lines up with common cage bolt spacing and uses the frame's existing bosses or B-RAD hardware. Check clearances on your specific frame and measure bottle position options before final installation.

• Fits most two-bolt bottle cages and standard boss spacing.
• Anodized finish coordinates with other Wolf Tooth parts for a matched setup.
• Verify frame clearance and bolt fitment before full installation.

How do I install and maintain the B-RAD Mounting Base?

Installation is straightforward: align the base with your frame bosses or B-RAD plate, insert bolts, and torque to 3–4 Nm. Periodically check bolt torque and inspect the anodized surface for wear if you ride in wet or abrasive conditions. Replace hardware if threads show damage or if the load rating may be exceeded by accessories.

• Install using appropriate bolts and torque wrench set to 3–4 Nm.
• Inspect mounting bolts and anodizing regularly for corrosion or wear.
• Do not exceed the 1700 g load rating to maintain safe performance.

Who is this for: The Wolf Tooth B-RAD Mounting Base suits riders who need to reposition a bottle cage on compact frames, full-suspension mountain bikes, or any setup where standard boss placement interferes with hardware or pedaling. It appeals to cyclists who want a lightweight, machined-aluminum solution that matches other Wolf Tooth components and keeps hydration accessible without permanent frame changes.
