Shimano Dura-Ace Bottom Bracket Cups
$32.99
Details
Shimano's Dura-Ace Bottom Bracket Cups are perfect for Shimano's Dura-Ace Crankset. They feature super-smooth sealed bearings, a plastic sleeve for additional protection, and they come in English and Italian threading.
For optimum shifting and braking, Shimano 7900 Dura-Ace components are best as a system (they're not recommended for use with previous versions of Dura-Ace).
