NEW NOS Shimano Dura Ace 9000 38 Tooth Chainring for 52-38 11 Speed FC-9000

Description

Shimano Dura Ace FC-9000 38T Chainring
38 Tooth, optimized as the inner ring for a 52/38 set. Should be usable with other size big rings but it truly works best with its matching 52 big ring due to its shift ramp placement.
Uses Shimano's asymmetric 110 BCD 4-bolt pattern and will work with Dura Ace 9000, Ultegra 6800, and 105 5800 cranks only. Newer Shimano 11 speed cranks such as Dura Ace 9100 will not fit this ring without some modifications.
These rings are out of production and rare at this point in time. Great opportunity to size down from a standard 53/39 ring configuration without resorting to compact gearing.
Condition is NEW in packaging.
