not that this is definitive or anything, buy Cambria Bike Outfitters (uncle Cambria i call him) has DT straight gauge SS spokes for 40 cents each in many different lengths. but i have always reused my spokes if length is not an issue. maybe it's because i've only busted one spoke in about 30,000 miles and that was seventeen years ago.

just watch, now that i've said it, they'll be popping like William Shatner's shirt buttons!
