## Description

ROCKBROS Bike Frame Bag Waterproof Bicycle Triangle Frame Pack Reflective Top Tube Pouch Large Capacity Bicycle Accessories for MTB Road Bike Black 3L : desertcart.co.uk: Sports & Outdoors

Review: Really good - Good bit of kit this. Can hold a surprising amount of stuff (shackle lock, sandwich, flask, jacket, keys and wallet comfortably), doesn’t move about once attached. Easy to install. One side gives you access to the bulk of the bag, the other side is a slip pocket for keys, wallet etc. Haven’t had it out in the rain but you can tell it’ll hold up well in even the most determined downpours. You’d probably get away with submerging it if you had to! Put it on and forget about it.
Review: Really nice and thin - If you are worried about rubbing your knees against a bag, that one is for you, it's so slim it practically hides under the top tube of my bike. Still manages to hold a phone, a battery pack, a few energy bars, usb cables and a few bike-related items. Really nice. It's also asymmetrical at the ends so you can find the best fit for your bike geometry. And one really important thing for me - it doesn't make a sound. You might not find it important, but when I had to listen my under-saddle bag squeaking for 10 hours last weekend, it was really annoying. Rockbros didn't make a sound, all I needed was to take care of the content - make sure nothing tumbles around - and it was a blast.
