ROCKBROS Bike Handlebar Extender 2PCS 25.3cm Carbon-Aluminum Mount for Phone GPS Speedometer

ROCKBROS Bike Handlebar Extender is a lightweight carbon-fiber and aluminum 2-piece mounting bar that gives your handlebars extra space for a phone, GPS, speedometer, lights, and accessories.

If your cockpit is cluttered or your primary handlebar lacks room for a cycling computer or smartphone, this pair of ROCKBROS extenders creates a stable, low-profile platform that keeps devices centered and visible. Each extender combines a long 25.3 cm arm with a durable mounting clamp designed to fit standard to oversized handlebars, plus protective rubber lining, corrosion-resistant fasteners, and simple tools for quick setup.

How does the extender improve device placement on busy handlebars?

The extender relocates devices forward of the stem to free up space and place screens within your natural line of sight. Its 25.3 cm length moves gadgets into a centered position and reduces interference with brake levers and grips.

• Long 25.3 cm arm positions devices ahead of stem
• Works with phones, GPS units, speedometers, and lights
• Centers accessories for balanced weight distribution
• Low-profile design preserves aerodynamic look

Will this fit my handlebar size and bike type?

The clamp accommodates a broad range of bar diameters, from narrow road bars up to many oversized mountain or e-bike bars. Check your bar diameter (20–32 mm range) before purchase to ensure compatibility.

• Designed for handlebars between roughly 20 mm and 32 mm diameter
• Includes adjustable screw buckle for a secure fit
• Rubber lining protects paint and prevents slipping
• Compatible with road, gravel, hybrid, and many e-bikes

How durable and lightweight is the extender for regular riding?

Combining carbon fiber tubing with aluminum alloy brackets balances strength and minimal weight so the extenders add little mass while staying stable under vibration. Corrosion-resistant screws and a robust clamp design keep attachments safe over repeated rides.

• Carbon fiber main tube for a lightweight rigid arm
• Aluminum alloy brackets resist impact and flex
• Each piece weighs only around an ounce to a few ounces
• High-quality screws and hex wrench included for secure fastening

How easy is it to install and remove when needed?

Installation is straightforward and requires the included hex wrench; the clamp tightens around the bar and the extender slides into place. Rubber straps and precise hardware ensure a firm hold without over-torquing.

• Tool included (hex wrench) for immediate setup
• Durable screw buckle system prevents loosening during rides
• Rubber interior straps reduce slipping and protect finish
• Quick to detach for storage or to move between bikes

Who is this for: Cyclists who need extra real estate on their handlebars — commuters, road riders, gravel and mountain cyclists, and e-bike users who want to mount phones, bike computers, lights, or other accessories without crowding controls. This 2-piece ROCKBROS extender set is best for riders who want a strong yet lightweight solution that fits a wide range of bar sizes and keeps devices firmly in view.
