"The SQR moves a Carradice seat bag up and away from your legs. It also has a quick release so that you can take off the bag when you get off the bike.
This item takes about 15-30 minutes to install the first time.
There are two drawbacks. The first is that your bag will hang low. Unlike bag supports (such as the bagman), the SQR does not have a lower strut to hold the bag upward. The other thing is that the bag dangles a bit and will hit the SQR frame when you get off the saddle to climb a hill. This is annoying."
Pros: High Quality, Good Fit
Cons: Not Enough Features, does not hold bag tightly
