I just got one. Not much experience yet. I like that it's longer than the other ones my bike shop had -- with 26" wheels, it's pretty easy to hit your heels on whatever's mounted there even as far back as this is. The mechanism for attaching uses tubes in a little pivot joint. This has upsides and downsides. Upside is that it's much stronger and lighter than the normal mechanism (where you bend dinky sheet metal). Downside is that they can easily run into the rack where they stick out in back. You may need to dremel them off to shorten them. This isn't a big deal if you have a dremel, but if not, you won't be able to mount it on some bikes, and on others, it may interfere with how the panniers mount. Civia appears to have fixed this in the Loring rack, but I'd be worried about brake clearance.
