Def Star Sprockets Are Here!



We've been riding 48 Spline Sprockets since they hit the fixed gear world, and while there are many options available, we've always felt like we could improve the breed.  So we did.

Enter the Def Star.

Our big twist is the clocked splines which allow for weight savings, while still maintaining exceptional strength.  A cutout on one side, means a spline on the other and vice versa. In addition, rather than the standard 6mm thickness, the Def Star is 8mm thick.

Basically it was made to handle whatever you can throw at it and still only weighs in at 147g for the 33t version.

We've been working on the design for over two years, and it's telling that all of our original proto's are still being ridden today.  We believe that this is definitely the best sprocket on the market and invite you to check it out.

P.S. Yes we have a 28t version on the way.

Material: 7075 T6 Aluminum

Weight: 147g

Thickness: 8mm

Spline: 48 spline, 19mm

MSRP: $65


Available at your local bike shop now.
