Astrum SH300 · Bike phone mount reference
The Astrum SH300 manufacturer reference describes an adhesive quick-release phone mount for bicycles and motorcycles, with angle adjustment at the handlebar. Check the supplied attachment style before ordering: the current product images show different holder designs.
Match the attachment
The SH300 reference uses an adhesive phone attachment and a twist-lock release. Confirm the mounting surface, phone or case suitability and included parts before fitting it. A jaw-style phone cradle is a different attachment design and should not be assumed to be included.
Set the position first
Astrum lists mounting diameters of 22 mm, 25.4 mm and 32 mm, with a rotatable head for setting the viewing angle. Follow the supplied fitting instructions and check the mount before use. A mount’s weather-resistance reference does not establish water resistance for a fitted phone.
Supplied design requires confirmation: the SH300 manufacturer reference is an adhesive quick-release mount, while the main product image shows a jaw-style cradle. Specifications below describe the SH300 reference, not certification of a different pictured mount. Phone/case compatibility must be checked before fitting.
