612 track rings are the perfect compliment to any 144BCD crankset. They are made from 7000 series aluminum and feature a durable and lovely anodized finish.

We are making them in popular and not so popular sizes that we hope to popularize. Ever ride a 42X16? I do and can tell you that it’s an awesome around town or freestyle gear, but until now 144BCD 42 tooth rings have been nigh impossible to find (believe me I’ve tried).

Maybe you ride a 44X16 on the street, but it’s a little tall and you’d like more skid patches to save on tire wear. So try our 43 tooth ring. It’s a prime number and when paired with a 16 makes a great city ratio.
