Are 6600 and 6700 10 speed cassettes interchangable?

Whats the actual difference between them?

  • Yes, interchangeable no probs, along with 105 10 speed and DA. 6600 seems to come with better ratio options, they did when I was buying, not sure if 6700 has been updated with more options now? 6700 supposed to have slightly different ramping on the teeth etc for "better changes" along with the 6700 directional chain. In practice I havn`t noticed any difference using a mixture of 6600 and 6700. They all shift well, and run quietly in use. Buy the one that suits your ratio and budget requirements. :)
