The Digirit Rear Cog Adapter is an adapter base designed specifically for Digirit Carbon Cogs. It must be used together with the corresponding Digirit carbon cog in order to install onto compatible fixed gear hub threads.
For track bike and single speed riders who need to change gear ratios quickly, this removable cog system improves replacement efficiency and gives drivetrain setups more flexibility. Riders can more easily match different Digirit carbon cog sizes according to training, commuting, track use or changing riding conditions.
This adapter is made from 7075-T6 aluminum alloy and finished with black anodizing for improved surface quality and durability. The thread specification is 1.375" x 24TPI, making it compatible with suitable fixed gear hubs. At approximately 8g, it balances low weight with practical function.
