Review: Seems perfect! - I bought this top tube bag to replace a bag that was too small for my new phone. I am 5'3" and my bike is a 50" frame, so I don't have a lot of extra space to work with. I was concerned at first that this bag would be too big, and in my way. The slim design alleviates that concern because I can still straddle my bike with enough room for my legs. I don't notice it on my bike at all, and it will fit my phone, wallet, and other small personal items that I don't want to put in my jersey pockets. I like the elastic attachments...fits my bike great and looks clean. I've only had it a week, so I don't know how the elastic will hold up, but it's a plus over the velcro. Hoping I will get substantial use from it.
Review: Perfect Bike Accessory – Sleek, Functional, and Durable! - I recently purchased the ROCKBROS top tube bike bag and couldn’t be happier with the product. It fits securely on my bike’s frame with zero wobble, even during longer rides or bumpier terrain. The material feels high-quality and weather-resistant, so I don’t worry about my phone or essentials getting wet. The best feature for me is the convenient phone compartment. It’s the perfect size to hold my iPhone and keys, without getting in the way of pedaling. For under $25, this is an incredible value. If you’re a casual rider or a more serious cyclist, this bag is a smart upgrade. Highly recommended!

### ⭐⭐⭐⭐ Good bag, but the zipper…
*by G***R on March 31, 2022*

I like this bag, so much I have purchased 4. My current iPhone is the 11 ProMax, and it fits (a little tight, but that’s ok) plus room for a a bar, ID/cash, keys and, currently, a mask. It’s been great, comes with LONG straps. Two complaints:1) very minor, but the knot on the side is consistently tied at the rear of the bag, and hits my right knee with each stroke. That picture I attached is an easy fix, but would be unnecessary if installed in the better (I think) position originally; and 2) the zipper is a bit funky. It stays waterproof, for the most part, and when new operates well. However, over time, especially if it sits idle, corrosion sets in and it becomes hard to operate, to the point that lube didn’t help, and on one of the bags the pull broke. I bought another bag but think this is a design flaw. The problem is accelerated because the bag sits in the “sweat zone” on the bike. (If you don’t sweat while riding, no problem.) It would be good to know the best lube to use (which oil works best without melting the plastic zipper, is silicone spray ok, should I use wax?) Also, is there a recommendation to wash it? How often? With what? I can experiment, but it would be most BROS-like I think if the company (or distributor) shared guidance and attention to detail.
