Fidlock Vacuum Ahead Cap Base is a phone holder mounted in place of the headset top cap, designed to securely attach a smartphone using the Fidlock Vacuum magnetic and suction mounting system.
Key Features
Construction and Design
The holder is installed in place of the standard headset top cap, positioning the phone centrally above the stem. This setup looks clean, keeps the handlebar free from extra clamps and allows the screen to remain easy to see while riding.
The black, low-profile construction suits road, gravel, MTB, trekking, city and electric bikes. The Fidlock Vacuum system combines magnetic guidance with vacuum suction, allowing the phone to snap onto the base quickly and remain stable during the ride.
Main Functions
The holder allows the phone to be attached and removed with one hand. The phone is released by pressing the side lever, making it easy to remove during short stops or after the ride.
The phone can be rotated 360°, allowing the screen to be used in portrait or landscape position. This is useful for navigation, training apps, route tracking and viewing ride data.
Use and Compatibility
Fidlock Vacuum Ahead Cap Base is mounted in place of the bicycle’s headset top cap and fixed through the headset system. This mounting style is especially suitable for riders who want to keep the handlebar free from additional holders.
The holder works only with a compatible Fidlock Vacuum phone case or universal Vacuum adapter. It is not intended for direct use with a standard phone case without a Vacuum system connection.
Additional Features
The central mounting position keeps the phone in a clearly visible place and reduces the need to turn the head when checking the screen. This is helpful when following navigation or monitoring training data.
The low-profile base remains compact even when the phone is not attached. Before every ride, it is recommended to check that the base, phone case and Vacuum connection are clean and properly locked in place.
Summary
Fidlock Vacuum Ahead Cap Base is made for cyclists who want a secure and tidy way to mount their phone centrally above the stem. It is best suited for road, gravel, MTB, trekking and city riders who value magnetic-vacuum attachment, one-handed use, 360° rotation and a clear handlebar area.
