Direct mount chainrings for SRAM cranks with 8-bolt mounting replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet. 

Compatibility 

  • These direct mount chainrings will replace your existing chainring and spider or replace the direct mount chainring for SRAM AXS cranksets and other cranks that use the 8-bolt mounting. Most SRAM cranksets have traditionally used a 3-bolt mounting, but the 8-bolt mounting has always been used on the Quarq power meter cranks. Now some non-power meter cranks like SRAM AXS use the 8-bolt mounting. 
  • All SRAM Direct Mount DUB road cranksets use the 8-bolt mounting standard. These cranksets use either 107 BCD or 94 BCD; any of those cranksets with a removable spider use the 8-bolt mount.
  • Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud-shedding ability
  • 6mm offset 
  • Chainline 45mm
  • Use Drop-Stop B for all 9, 10, and 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo, SRAM Eagle, SRAM Road and Transmission (T-type) Flattop chains

Starting a StartUp is a must-read for anyone who wants to build something that matters
Format: Paperback
I rarely come across a book that so perfectly balances the technical and the personal in building a startup. Starting a StartUp: How to Build Something People Want does just that. It is less of a textbook and more of a companion for founders who want to build with heart and wisdom. What I loved most: Actionable, no-fluff advice. Instead of lofty theories, the book dives right into what really matters: validating ideas, talking to users, iterating fast, and scaling smart. The checklists, templates, and real-world examples make it easy to move from reading to doing. Psychology + empathy. It does not treat an entrepreneur like a machine. The author emphasizes dealing with uncertainty, failure, and the emotional rollercoaster of starting something new. That human touch elevates it from “startup guide” to “founder guide.” Accessible to novices and veterans alike. Whether you are building your first side project or scaling your third company, there is value here: reminders about customer obsession, principles for experimentation, and stories that resonate at any stage. Readable and engaging. The prose is clear, the chapters are well-paced, and every chapter ends with key takeaways that help cement the learning. Starting a StartUp is a must-read for anyone who wants to build something that matters, not just for profits but for people. I am recommending it to friends, colleagues, and especially the next generation of makers I mentor. Highly, highly recommended. ⭐️⭐️⭐️⭐️⭐️

Great book for learning about startup culture.
Format: Paperback, Format: Paperback
I had this book for a while did not have the chance to read as soon as I got it. Recently finished reading it and learned a lot of great things about startup terminology and how to be fast and how to iterate things in a right way, how to go deep in the problem. Identify pain points for the problem etc. Overall great teacher for anybody who wants to get grasp of a being in startup world.

Learning Faster, Failing Smarter
Format: Paperback
This book is truly amazing. Each chapter offers so much to learn. It helped me review what I’ve missed so far, anticipate future challenges, and prepare ways to reduce the chances of failure. It reminded me that failure is inevitable, but the speed of learning, adapting, and retrying makes all the difference. I learned that luck comes through action, ownership is everything, and true success lies in persistence and focus. The book also emphasizes solving real problems with humility, data, and continuous iteration. I’m truly grateful to have found this book — it changed the way I think about challenges and growth.
