01BASKETBALL & BASKETBALL ACCESSORIES
Precision alignment for every ride
The Cellet dual ball adapter sits discreetly between your handlebars and navigation device, a slender link in the chain of control. Its matte black finish blends into the bike’s silhouette while preparing for movement.
This connector translates standard 25mm mounting arms into the 17mm pattern required by Garmin GPS units and iBOLT holders. It suits riders who demand precise, multi-angle positioning without bulky hardware.


02MATERIALS
Aluminum core with resilient coating
The central rod is forged from aluminum alloy, providing rigidity against vibration on rough terrain. A layer of TPU over-molding covers the ball joints, creating a non-slip surface that resists wear. This composite construction balances lightness with durability, ensuring the connection remains secure through repeated adjustments.

04IN USE
Full-range rotational freedom
With dual ball adjustments, the device rotates freely through 360 degrees. You can angle the screen toward your line of sight or tilt it away from glare, then lock it firmly in place. The mechanism allows for micro-adjustments, so the display stays level even when the bike leans into a corner.
DETAILS
Compact dimensions and lightweight build
Measuring 2.5 inches from end to end, the arm extends just enough to clear handlebar clutter without adding visual bulk. The packing carton weighs only 0.1 kg, indicating a featherlight component that adds negligible mass to the front end. Mounts, holders, and devices are sold separately, keeping this piece purely functional.
