The Nitto R and T cages just may be the best looking bottle cages you can find. With their dainty yet strong TIG welded stainless steel wire frame construction they keep a firm grip on your bottle and look good doing it.
The R cage is described by Nitto as their road racing cage. This means if you are going to be hitting the rough stuff more often than not, but still want this level of elegance, have a look at the Nitto T Bottle Cage.
The R cage weighs in at 53g and is handmade with care in Japan.
