Hello and thanks for checking out this listing of a new English thread Shimano Dura-Ace 7700 BB-7700 Octalink bottom bracket. This bottom bracket was rescued from the back stock of a high-end bicycle shop and will come to you in the true New Old Stock, new-in-box condition seen in the included photographs.

This BB is compatible with Shimano Octalink, "double" two-ring cranksets thanks to its 109.5mm long spindle. For use with English threaded frames only, 68mm shell width and 1.37x24t. Roller and needle bearings ensure smooth performance and superlative life. It's a shame that they "Don't make them like this anymore!"

I was fortunate to find a small handful of these bottom brackets, each is in the same mint condition as the one seen in the included photographs. Boxes show faint signs of "shop wear" due to display and storage the past twenty odd years.

Increasingly hard to find! Enjoy FREE SHIPPING within the USA!
