Tofern Triangle Bike Bag Large, Waterproof Top Tube Saddle Bag, Large Capacity Front Frame Bike Bag, Under Frame Corner Pouch Tool Bag for Mountain Bike

I used for my controller kit

Difficult access,not cheap-a huge backpack has this price.

Very well made and excellent velcro strapsI just cant use this when I have water bottles on my seat tube and down tube - while having this extra storage would be hand for layers it is not more important than water/electrolytes.I am 6' tall and my road bike is 56cm I think you would need a very large frame to use this product in conjunction with water bottles

Worth every penny, however I would love a bigger version.6-8L would have been nice.

Great for the price. It gives you a lot of extra space for snack or food storage

Good quality and holds alot of items, such as keys, large phone (Samsung Galaxy Note size) with space, fits my mountain bike nicely, not to bulky. Great buy.

Not as big as I expected but does the job

Very large sturdy bike bag, but saying that it looks good on the frame and not out of place. I have tubes, gas canisters tire levers amd spare lights.. plus a compartment left over. Id recommend this completely. Everything dry after a downpour.. zips easy with gloves.
