Greetings all. I posted this in the Utility thread but folks there suggested I post here. Problem: When riding clipless, my heels hit any rear pannier other than those that hang high on the rear rack. I need to replace my rear rack anyway, and was hoping to find one that's a few inches LONGER so that I can slide panniers just two or three inches back and not hit my heel.

Internet search has not lead me to anything that definitely is longer, so I'm asking you all to point me in the right direction. Will be bike commuting daily this upcoming school year (I'm a teacher) and want to get everything set up solid.

Also, since I'm spending the money, it'd be nice to get something durable enough to use for some minor touring in the future...
So: capable of carrying bigger loads, able to fit over 27 inch rims, and extended enough to not hit heels on panniers.

Thanks!
