I recently got a commuter bike and am having a difficult time figuring out what type of racks & bag/basket to get. I got a Specialized Globe Centrum. It's a single speed with 26" tires. You can see it here:

My commute is under 6 miles each way. I went with the single speed due to the simplicity and my route is relatively flat.

My LBS sold me a rear rack that extends off the seat post. I got a bag for it, but the bag doesn't seem stable. It attaches to the rack with velcro but with a load in it, it seems top heavy. Hope this makes sense.

I'm starting to think I may be better off with a traditional rack and maybe a basket of some sort. I'm not sure I really need the bag. It does have fold out panniers on it.

If not a basket, I was thinking about the Topeak MTX series. The bag attaches to the rack with a rail and quick release set up. Again, I'm not so sure I need a bag system.

Any thoughts or ideas for me. I know my LBS doesn't like taking things back, but I don't think what I have now is what I want/need.

Thanks,
Kerry
