Mountain Bike 30t Single Chainring

These rings are designed to mount in the small ring position of a standard mountain bike crank and the chainring includes some offset for chain line correction (as can be seen in the images above).  Using the 64mm mounting location instead of the 104mm BCD makes the ring stronger, and lets the chain avoid issues of interaction with the crank arms like other popular 30t single chainrings.

WickWerks 30t single chainring offers the same advantages for chain retention, increased durability and flexible tooth location as do the larger Z-Ring sizes.  These particular rings are intended for converting from a mountain triple or a mountain double (2X) to a Z-Ring 1X single.  It’s a simple conversion that does NOT require a new crank!

Chainrings for the serious rider

Chainrings For The Serious Rider

Founded and developed by cyclists, WickWërks offers advanced component solutions for an improved riding experience. By refining existing technologies and innovating new ones, our products provide a competitive advantage to racers, and a more enjoyable ride to recreational cyclists. We are proud to offer choices that makes a noticeable difference.


Details Matter

With Chainrings, the details make all the difference. These are the “Radical Ramps” of our BRIDGE Shift Technology. Unlike the shifting pins seen on most chainrings, these ramps are like big hands reaching out to grab a whole fist full of chain to SHIFT — when you command it.
So, when we say “Shift Your Expectations”, it’s more than just a play on words.
