Blackburn EX-Trunk Bag
- Gender: Male
- Familiarity: I've used it several times
The Blackburn EX-Trunk Bag is designed thoughtfully, like a mini shoulder bag for your rear bike rack. It has enough pockets to store head- and tail-lights, sunglasses, bungees, etc. I used the bag for several weeks, summer going into fall, in sun, wind, and rain, and exclusively in the city.
The main compartment was big enough to hold two extra-wide U locks. On top of those, there was still room for gloves, pumps, etc. The shoulder strap made it convenient to carry it around off of the bike.
The bag's extra-wide bottom, however, made it difficult to secure the velcro straps underneath the rack. Blackburn should have used a four-point strap system to secure the bag using the outer most rack rails. There was so much extra velcro strap that both straps barely had any velcro to attach to themselves once you threaded them under the rack and tried to attach them on the other side.
As a result, the bag slipped to one side or the other because it was too wide for my standard-width rack. Because of its width, a loaded or nearly empty bag could not be centered on the rack without its slipping quite a ways off to one side or the other.
Using a bungee pulled diagonally over the bag helped, but simply going off a curb made me look back to see if it were still on the rack. Otherwise, it is beautifully detailed from material to compartments and water-proof cover (used without the cover in the rain did not show any leaks).
There is no real rear mount for a blinky, as described on Blackburn's information card, and the water bottle holder may only be big enough to fit a 12oz soda can.
Hopefully, Blackburn will redesign this bag. I have had amazing Blackburn courier bags and currently use their great, tiny front and rear Flea lights on my helmet.
