    Custom CNC Chainring

    I finally got my custom machined chainrings done for my Rotor cranks on my S-Works. I did all the design, reverse engineering, and machining myself. I couldn't find any mountain specific 39T 110 bcd rings for the life of me so I decided I would make my own. The only thing I didn't do was was the anodizing which was done by a fellow MTBR member.

    That's cool, but what is "mountain specific" about it?

    No, orders. Just a one-off for myself. And the only 5 bolt 110bcd rings i could find were inner road rings with no ramping or pins.

    Final product looks great! I'm glad the anodizing finally worked out and you got the rings back in time. I'll be curious to see how the ano holds up with long term use.
