I have that rack, used it before I got a bike that has rack mounts, along with their trunk bag. That trunk bag, while it was a nice idea, kinda became an issue. The bag snaps into the back of the rack with a spring action latch, and the front hooks in. That spring at the back (there is a big push button to open the latch) got weak and the bag would slide back and forth, compressing the spring (opening the latch) and it almost fell off. I had to open the mechanism and install a stronger spring. I was nervous about it after, so slid a velcro tie-wrap around the front strap loop and would loop it around the seatpost to make sure the bag would not slide back if the rear spring got weak again.
The other issue was weight. No, not the weight weenie weight (I think the Bontrager is rather light for that type of rack) but where the weight was. I was putting several days worth of lunches and a shirt and shoes in it and the weight felt rather destabilizing being up so high. I then got a bike with rack mounts and bought the Bontrager rackmount rack and panniers. With the trunk for lighter stuff like clothing, and the panniers for food, jacket and shoes, that worked much better in terms of weight distribution. But it was overall heavy.
So I weight weenied and bought one of those 'rackless' bags, the Revelate Pika. Yea it's for rackless trekking, but the idea sounded good. No heavy metal rack. It's not for dress clothes (it's a compression bag) and not for computers and stuff like that, it's for clothing. Being I take the car on Monday now and take a week's worth of food and other stuff and just need the bag for a shirt, pants, gloves and jacket, it made more sense for me. It looks like a giant black banana that's about 3 times longer than the seat. It weighs 12 oz and I can get a change of clothes and a cycling jacket in it along with the typical cycling accessories. A small bag up front carries the tubes and tools and I am done. No more racks.
