I've got a 'Specialized Sirrus Elite' bike with a 'Tortec Velocity Slimline' rear rack on it (black)
Looks good and does the job.
Im in UK: try this to get info http://www.cyclestore.co.uk/productD...&categoryID=84

Rack weighs 470g and takes up to 25Kg

These are narrow at top so no room on top of rack for much but it does mean
slimmer look to it all and I guess weight is more over the centre of the wheel
handy if you're only taking one bag.
Check fitting of your bag/pannier though as rack is a sharp V shape at wheel juntion point
so no-can attach an eg Arkel fitting to it.
