  • Topeak Dynapack DX Saddle Bag is rated 4.3 out of 5 by 4.
    Rated 4 out of 5 by from Good idea Good idea for carrying more than a seatpost bag can fit without going as far as using panniers. Easy to attach and detach, and to move to another bike. Quality seems good and it doesn't look too bad on the back of a bike. The plastic attachment will be the weak point but I've rigged up a support system with some S hooks and para cord that will hopefully overcome that. Overall, recommended

    Rated 5 out of 5 by from Modern and sleek New style to the market place and surely a winner. Rides behind like it just done care. True it does take up a lot of seatpost so watch for that. Simple to remove when not needed, I have taped the clip in place so can remove the whole lot. Such a well thought out product. None of the fiddly tight zips or small space I have become used to with latest styles. Love it is not too strong...

    Rated 5 out of 5 by from As Big as you'll get and quality too This review is all the more relevant now that the bag has done 2 of us proud on a cycle trip London-Paris (accompanied by a pair of panniers). It's well made with a secure fitting that never budged. From my fairly extensive research 10L is as big as you'll get for a saddle / seatpost bag but unlike others that I nearly bought this one is far less compartmentalised so will carry larger things. It does have velcro fixed dividers if you want, splitting it into 3 sections. It also has a useful zipped section in the lid. We had the zips up and down loads but the test will come over time as it's usually the zips on products that go first. Easy to take off and we just used the frame handle to carry although you can unvelcro the bag from the frame if you wish. Fantastic product already earned it's keep.

    Rated 3 out of 5 by from nice bag but unsuitable for my bike Liked the bag and the system. However as I don't have a mass of seat post showing, (about a foot), the bag was too close to the underside of the saddle.This made opening the bag awkward as it does not sit far enough out on the bracket. Returned for a refund.
