Blackspire SuperPro Chainring 120/80mm BCD
Need a chainring to go with your XX, X0, X9, X7 or X5 setup? Blackspire has just the chainring for you. Several enhancements provide an overall smoother shifting experience.
I picked up this ring in the 120 BCD 39t size to replace my worn out XX stock ring back in early January. On my first ride I felt a dramatic change in better shifting. The feed ramps are better quality and more numerous allowing faster more accurate gear changes. The ring is a higher grade aluminum with better longevity and doesn't flex at all when shifting under load. As soon as my small ring wears out I'll be replacing it with the 26t 80 BCD ring. In this case due to killer pricing the value far exceeds the small price in quality.
