i reckon this wont help you, but i have a suggestion for anyone in cape town who wants to buy bicycle shoes and well, any other parts.
give bellville cycles a shot (you can get the number from the phone book), they have good stuff and great prices and the guys there (if you ask for advice) will spend ages with you telling you anything you want to know.
you can see they a shop that cares where as other shops in cape town are so profit driven, they'll say 1 thing and hope u understand and buy the product or just leave.
