Quite a heavy bit of kit to be carting around but secure, bag locks on nicely and useful to carry a change of clothes or some food on the work commute. Design seems pretty robust and it's nice and simple so can't see anything much going wrong with it.
Fitting this was a breeze. I needed something to turn my road bike into a commuter, and these fit the bill well. Build quality seems very good, the test of time will tell. Highly recommended.
Excellent rack, really quite secure. I don't have the Topeak bag to go on it but another similar rack bag fits quite nicely, though doesn't make use of the quick release features. The integrated storage drawer is an nice idea, but it's too small for an inner tube and too big for my tools, so they rattle around too much. Those with smaller tyres may get on better (<1.5").
Overall makes the commute much nicer, no more sweaty back.
