Review on Topeak Wedge Pack Fixer Medium by Keith Harris

Suitable as a small bike backpack if you don't have to take too much with you, just the essentials. It's perfect for your wallet, keys, phone and rock bar - and that's because it doesn't fold out. Enough room for even more stuff (provided it's the right width and length) if you expand it. The quick release is also a really nice feature, although most of the time I just take my entire seat off and take it with me just to be safe. There is also an additional velcro strap which makes the quick release not as quick when using a strap. But still a solid product. The all-weather cover is also very good, although you have to detach the backpack from the seat to put it on, which can be a little awkward if you get caught in the middle of a downpour. Attaching it to my bike seat was fairly easy, although it doesn't fit perfectly. This has to happen with every product because no one can design something that fits every bike and seat perfectly.
