BRCOVAN 1" Ball Handlebar Clamp Mount Base 2-Pack — Aluminum Alloy, TPU Over-Molded Ball, Fits 0.5"–1.26" Bars

BRCOVAN's 2-pack 1-inch ball handlebar clamp bases are lightweight aluminum mounts with TPU over-molded balls designed to secure accessories to a wide range of round rails without tools.

If you need a compact, durable mounting base for phone holders, action cameras, GPS units or mirror-mounted accessories, these clamps give a solid 1" ball interface compatible with most B-size arms and RAM-style hardware. Each pack includes multiple soft rubber inserts so the clamp fits handlebars from about 0.5" up to 1.26" in diameter, and the aluminum body with anodized finish resists wear in outdoor conditions.

How does the clamp adapt to different handlebar diameters?

The clamp ships with four removable rubber ring inserts that let you match the internal diameter to your tube or mirror stem. Insert the ring that most closely fits the bar, or remove inserts to reach the largest 1.26" opening.r>

• Includes inserts sized for 0.5" (12mm), 0.87" (22mm), 1" (25.4mm), and 1.125" (28.6mm)
• No tools required for installing or removing the mount
• Full-open hole (no insert) equals 1.26" (32mm) diameter

Will this stay tight under vibration and rough roads?

The design combines a lock bolt with the rubber-insert interface to resist rotation and loosening from vibration. TPU ball head and snug rubber inserts reduce micro-movement between the clamp and your rail, keeping attached arms steady during rides.

• Lock-bolt secures the clamp to the handlebar or mirror stem
• Rubber inserts cushion and prevent slip under vibration
• TPU over-molded ball resists wear and provides an anti-slip contact point

What materials and finishes are used for durability?

The mount body is CNC-machined from 6061-T6 aluminum alloy and given a hard anodized surface to withstand exposure and abrasion. The 1" ball is over-molded with TPU to improve grip and longevity compared with plain plastic or bare metal balls.

• 6061-T6 aluminum alloy body for strength and light weight
• Hard anodized finish for corrosion and wear resistance
• TPU over-molded ball head for anti-slip, wear-resistant contact

Which arms and accessories are compatible with the 1" ball?

These bases accept any accessory or arm that uses a standard B-size 1" ball mounting pattern. They work seamlessly with BRCOVAN B-size double-socket arms and most RAM-style arms and holders that match the 1" ball spec.

• Compatible with BRCOVAN B-size 1" ball double-socket arms
• Works with many RAM-style 1" ball mounting accessories
• Ideal for phones, GPS units, action cameras, mirrors, and other swivel-mounted devices

Who is this for: Riders, commuters, and installers who want a compact, versatile 1" ball mounting base that fits multiple rail sizes without machining or permanent clamps. It's well suited for motorcyclists, e-bike and bicycle riders, scooter owners, and anyone mounting accessories to round rails or mirror stems who needs corrosion-resistant aluminum construction and vibration-resistant retention.
