The ROCKBROS Bike Phone Mount Bag Waterproof Bike Phone Front Frame Bag under 5.8/ 6.5 is a purpose-built storage solution that attaches directly to the front triangle of bicycles with fork widths between 5.8 mm and 6.5 mm.

Frequently Asked Questions
What items can I store in the ROCKBROS front frame bag?
▾
The bag’s interior is designed for versatility. It comfortably holds a smartphone, a CO2 inflator, a mini pump up to 8.2 inches, a spare tube, small snacks, a wallet, and a set of basic tools such as tire levers and a multi-tool. The flexible TPU lining also accommodates keys and a compact first-aid kit.
Does the waterproof cover affect phone signal?
▾
The PU rain cover is thin enough that it does not noticeably degrade cellular or Bluetooth signals. Because the bag includes a TPU window for the touchscreen, you can still interact with the phone without removing it, and most riders report reliable connectivity even in heavy rain.
How do I install the bag on my bike?
▾
Installation takes under two minutes. First, open the three elastic belts and place the bag on the front triangle, aligning the mounting slots with the fork blades. Next, tighten the belts and secure the additional Velcro strap across the top. Finally, snap the rain cover over the pouch and verify that the zip is fully closed.
Is the bag compatible with bikes that have disc brakes?
▾
Yes, the bag mounts to the front triangle and does not interfere with disc brake rotors. The mounting belts wrap around the fork crown, leaving clearance for the brake caliper and rotor. As long as the fork width remains within 5.8 mm to 6.5 mm, the bag fits securely.
Can I use the bag on a mountain bike with a suspension fork?
▾
The bag works on most suspension forks that meet the 5.8 mm-6.5 mm width range. The flexible TPU material conforms to slight curvature, and the extra Velcro strap adds extra grip on the moving fork. However, very long travel forks may require a larger bag for optimal coverage.
