ROCKBROS Bicycle Frame Bag 1L/0.9L Lightweight Lightweight Lightweight Bike Front Bag MTB Gravel Resistant Compact Reflective Cycling Scratch Cuttable Portable Side Strap Polyester Black

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

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

good bag, stays put and elastic on the side is useful for attaching layers. bag squeaks on frame when it gets wet which is annoying

just the right width to suit my frame, trimmable velcro straps so no excess haing about to get caught against legs etc.usefull netted side pocket and inner big enough for an iphone x, keys, gels and cards (but not my wallet) etc

Bought this bag as was fed up with wearing a back pack which made me sweat more. I can just about get my iPhone 8+ inside so if you’ve got a bigger phone be careful. The string on the side doesn’t do much it’s not that tight, I put my tissue there and it fell out. Bag is very study and doesn’t move even in the bumpy red run.

Fitted it on the bike the day I received it and did not move it from there. Sits very well, just enough to squeeze in my S24 Ultra and have room for 2-3 snack bars.I love the color scheme as it matches my bike with silver and orange accents.Would have liked it to be 10% bigger than it actually is.

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

Seems very well made. Works well and sits nice and secure. I’ve been over some seriously bumpy tracks and it’s never moved a bit. Purchased one for a friend and he likes it just as much.
