One word of warning if your stem is low/slammed the front strap wont work and is not removable, I am super tall so I run 20-25mm of spacers and it's perfect. *I lined my bag with piece of plastic ruler and drilled it to fit my top tube mounts and bolted it on so I would not need the bottom straps, honestly should come pre drilled for as common as top tube bag mounts are now. Review: Great water resistance and holds a lot despite compact size - This bag has been so convienient for removing items from my pockets that loosely swing aroung in my shorts, or worse try to fall out, while Im riding. This allows me to keep them secured while still having easy access to them. Its also great at keeping them dry. The other day it was raining pretty heavy on my ride home. Including a few minutes where my bike was just sitting out in the rain before I came out to it to leave. Aside from a drop or two that made their way in when I was putting my stuff in there, the inside was nice and dry! Maybe a slight bit of dampness on the inside of the fabric, but nothing to complain about. Especially with how hard the rain was coming down. At one point the drops were hitting my arms so hard they started to sting a bit. Good product here. Zipper can be a tad finnicky at times but it seems to have a way it wants to be closed so once you learn that its fine. I just put a little chain lube on it to help it slide a bit smoother and its been fine ever since. ## Features - HIGH CAPACITY: 1.6L/1L capacity and extended design-size are big enough to store your wallet, energy gel, mobile phone, gloves, repair bike tool, power bank and so on - EXTRAWATERPROOF: Three-layer waterproof material: 840D Nylon + Internal PP board +TPU material and sealed adhesive zipper, which ensure the water will not flow into the bag - DURABLE & STEADY: The main material 840D nylon can be highly abrasion proof and durable.

Waterproofing is on point. Can just slip in an average battery bank and some snacks. It can kinda slip around on the top tube unless you put something grippier down around the tube. The only issue is that it’s really quite difficult to close unless you stop and use two hands. just collapses on itself. But not a dealbreaker in my eyes. ## Frequently Bought Together - ROCKBROS Bike Top Tube Bag Bicycle Front Frame Bag Waterproof Bike Pouch Pack Bike Phone Bag Cycling Accessories Pouch for Mountain Road Bike Large - Ascher Ultra Bright USB Rechargeable Bike Light Set, Powerful Bicycle Front Headlight and Back Taillight, 4 Light Modes, Easy to Install for Men Women Kids Road Mountain Cycling Black - ROCKBROS Bike Seat Bag, Bicycle Saddle Bag Under Seat 3D Shell Cycling Seat Pack for Mountain Road Bikes Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/64487978-rockbros-top-tube-bike-840d-nylon-waterproof-bag-bicycle-front](https://www.desertcart.tn/products/64487978-rockbros-top-tube-bike-840d-nylon-waterproof-bag-bicycle-front) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-05*
