This is basically the best rear rack you can buy. It has two horizontal rails at the top, so you can put your panniers on the lower rail and still strap something to the top. The struts to attach the rack to the chainstays are tubular steel, so they won't flex.
There's a light bracket on the rear, that will fit standard 2-hole rack mounted lights.
Tubus make high-quality steel (CrMo) racks, such as those featured on the Vivente World Randonneur touring bicycle. They're all made in Germany.
The Logo rear rack is designed for bikes that have eyelets above the rear wheel dropouts. However you can use it with bicycles with no such eyelets if you purchase the Tubus axle mounting kit.
