GUB Silicone Bicycle Phone Holder and Strap Computer Mount Options, Quick Release with Interchangeable Adapters for Road and Mountain Bikes

Choose a phone holder or a computer mount

This GUB listing has two separately purchased accessory types: the P13 silicone phone holder for a compatible bicycle computer mount, and the 630 silicone strap mount for a bicycle computer. Both are available in Black, Gray, Ivory and Purple. Select the accessory type as well as the color. The P13 option does not include the separate handlebar computer bracket, and the 630 option does not include the P13 phone holder. Photographs showing them together demonstrate how the two accessories can be used in combination.

P13 flexible phone holder for 4–7 inch phones

The P13 uses a silicone panel with four flexible corner loops and a PC computer-mount adapter. The source states a supported phone screen-size range of 4–7 inches and approximate panel dimensions of 144 × 65 × 12 mm. Its approximate net weight is 40 g with the Garmin-style adapter. The open layout leaves most of the screen visible. Check the fit with your phone and case, including the position of the camera, buttons and corner loops.

P13 interchangeable adapter interfaces

The P13 source photographs identify adapters compatible with Garmin, Bryton and Wahoo computer mounts. Select and fit the adapter corresponding to the mounting interface you intend to use. The illustrated computer extension bracket is a demonstration accessory, not part of the P13 option. The P13 packing image shows the silicone panel, adapter pieces, two M4 × 8 mm hex screws, a hex key, instructions and a retail box. Check the supplied instructions for assembly and adapter selection.

Portrait and landscape phone orientation

The P13 installation guide shows portrait orientation in the factory arrangement and landscape orientation after repositioning the adapter on the panel. Remove the adapter screws, change its orientation, then refit and tighten the screws as shown. Seat the selected adapter in a compatible computer mount and twist it to engage before fitting the phone. Put all four loops around the phone corners, then adjust them so they lie flat, symmetrically and with even tension.

630 adjustable silicone strap mount

The 630 uses a flexible silicone strap and a PC computer insert. Wrap the strap around a suitable handlebar or stem area, pass it through the opposite loop, pull it snug and engage the fastening position that fits the mounting area. Its multiple strap slots provide adjustment without separate tools for attaching the strap. The source illustrates both stem and handlebar placement, with round and shaped contact areas. Check the strap reach and full contact on your particular bicycle.

630 computer inserts and orientation adjustment

The 630 source shows a Garmin-style insert fitted to the mount and additional inserts compatible with CatEye, Bryton and Wahoo. Use the insert that corresponds to your computer interface. Changing the insert or rotating its orientation requires a hex key; the source recommends a 2 mm key and states that it is purchased separately for the 630. This differs from the hex key shown in the P13 package. The illustrated 630 head measures approximately 5 × 5 cm and the illustrated overall strap length is approximately 22.5 cm. Reference net weight is approximately 60 g for the mount with an insert.

Use the two accessories together

The 630 can be paired with the separately selected P13 phone holder using compatible interfaces. This provides a strap-mounted phone setup without the metal extension bracket shown in some P13 demonstration photos. The silicone contact surface beneath the 630 is textured to help it grip the mounting area. Confirm that the strap is secured and that the P13 adapter is fully engaged before using the combination.

Installation checks and package selection

Phones, bicycle computers, bicycles and metal extension brackets in the photos are demonstration items. Inspect the installed accessory for movement, confirm that the buckle and interface are engaged and check that cables and controls remain accessible. The P13 and 630 have different package contents and different functions, so choose the named option you need. Color options describe the silicone component; adapter pieces are shown in black. Reference measurements and colors can vary slightly by batch and display.
