Design Four - Production.


This is a simple and clean design that has made it as a production ring.

The design is one of my most popular and I have cut this design in just about every bolt pattern that has been produced.

Its simple design and clean lines make it look equally great on older crank designs as well as new generation crank arms.

 

 

I have this available in 144 BCD and 130 BCD  in 1/8 thick tooth thickness.....This Production ring is available in anodised blackFine Brushed Silver and Polished.

 

This model is designed for mounting on the outside of your crank arms. The tooth profile is flush with the rear of the ring for the best chainline.

 

Note: Polished and Brushed Silver  are prepared after the you have ordered the ring, so may add a few days to the delivery time.
