i can't speak to the direct comparison, but i've been riding 559s on my homer hilsen for a decade without a complaint. i find them perfectly able, even in the rain or on questionable / mountain bikey terrain (the kind of rides where people ask my least favorite question: "how are you making out on *that thing*?")
you might look into the paul racer as a centerpull option? i've only used the racer m, but it's a mighty fine brake, in my opinion. good luck paul takoma park, md. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
