ROCKBROS Bike Frame Bag Bicycle Pouch Top Tube Bag Crossbar Bicycle Pack for MTB Road and E-Bike 1L Fully Reflective Black

Nice piece of kit, fits well on the bike, and is at least showerproof. Otherwise I wish it were a little larger, to accommodate more items, but as it is it does the job.

Great little bike bag for keys/phone etc - fits a regular iPhone, the max version would go in but could be difficult to open while moving. Should be noted I tested it with a chunky case on my iPhone max so it may be ok without a case.

I wanted some additional occasional carrying capacity on my bike (in addition to a saddle bag)This seemed a reasonable option in terms of size, fitting method and priceIn summary - for the price its fineThe pictures show using one of the velcro straps under the down tube but I have used both straps under the seat tube with no issue. I will cut off the excess length from the longest strapIt seems to stay in place without needing any of the straps being tight which is good an dis easy to take off and refit - its been fine on both my road and MTB bikes. I have had no issues with it moving whilst ridingThe lace / straps on one side - no idea what you'd use that for - I think anything more than a few cm thick would just rub my knees all the time and fall outIt is not fully water proof - its OK but do not put anything that would be damaged by water in that's not also in a plastic bagI can just about get an inner tube, my phone (that's not quite the size of many very new phones) and a few gels in - this is what I wanted so that's OKI don't think its of the highest quality and I don't feel that it'll last years - but I am more than happy with it and no buyers regrets

This little bag is perfect, I can fit my phone inside ,gels a small pump ,very well made , excellent value for money 😀

If you need to take reading glasses it is great

Nice simple design. Fits easy. Elasticated drawstring on one side handy too for carrying a mini pump if your riding without a rucksack. I always have a tube tied to my frame but you could get 2 in here plus 4 small tyre levers. I use it for my phone. It's a Samsung A32 and fits but only just. Smaller iPhone will with better. It's never let water in yet

I was looking a bag to store a few things in rather than stuff them into my cycling jersey pockets. I bought this thinking it would be neat and quick access. I'll get straight to the point, this bag rubbed on my knees cycling while sitting and definitely while standing. This is not the bags fault of course, it's the position of the bag. The bag seems well made but there's no way of telling if it will last, and not sure how it will do in the rain. It's sturdy and sits in position but agin could be knocked around by knee hits.This will be a good bag for occasional use, maybe a long ride where you need extra supplies and quick access to those items. Other than that I would avoid and buy a frame bag that sits under the top tube (I did this and no leg rubbing issues).

Im always a bit paranoid that I'll have a problem when out on the bike such as a broken chain, puncture etc. and wont have the things I need to fix it. This little bag solves my problem, its big enough to contain the stuff I need in the way of tools, spare links and puncture patches and more. I have a folding ebike made by Samebike, the top tube is more like a girder than a tube so the rear strap on the bag is too short to go round it but I just extended it with a few inches of velcro strap and voila, fits a treat. For the casual cyclist its all you really need. It seems well made and shower proof and it can be removed in seconds if there is a risk of it getting stolen whilst the bike is left unattended. Very pleased with it
