Topeak Dynawedge Micro seat pack review

If you only carry a small amount of kit with you, but want to attach it to your bike rather than end up with bulging pockets, then the Dynawedge Micro might be the answer. With a capacity of just 350ml, there’s enough room for a spare tube, levers and a small multitool and that’s it. It does come with a removable internal pouch though, which uses Velcro to attach to the inside of the bag and could be used for some spare cash or other necessities.

The Dynawedge is a semi-rigid design made of EVA foam and has a long central water resistant zipper which opens along the rear and bottom of the pack. This would mean that the contents would fall out if you opened it when it’s attached to the bike, were it not for a nylon mesh which connects the two halves – again kept in place by Velcro.

Indeed Velcro is a recurring theme of the Dynawedge, as it uses two straps of the material to attach to the saddle rails. There’s also a rubber band strap to keep it looped around the seatpost. The attachment mechanism works pretty well, although since the Dynawedge is narrower than the gap between most saddles’ rails and the head of some seat posts can get in its way, I did find that occasionally one of the Velcro straps would come free. I also had to be careful how I mounted the rubber strap, as it could come loose and the tab on it tended to rub against my legs if it wasn’t centrally positioned.

Watch: What to pack for every sportive

Unlike many saddle packs, there’s no light loop, so if you want to show a rear lamp you will need to attach it to the frame. But since the Dynawedge is so diminutive, finding space for this really isn’t a problem.

Being rigid and made of water resistant materials, the Dynawedge has stood up well to the stream of muck and damp which its position on the bike exposes it to. But the small capacity has meant that I’ve ended up carrying more in my pockets than is my habit.

Topeak does make the Dynawedge in a larger Small size too, with 800ml volume, if you do need some extra capacity. There’s a weatherproof version too if you want to keep your valuables a bit better protected from the elements.
