  • Made for Gravity/Freeride
  • Extreme damping
  • Unique rubber compound

The world-class gravity grip featuring the factory compound was exactly what Tahnée Seagrave and her teammates from Canyon [CLLCTV] FMD Racing requested. Working together, the Ergon developers delivered the ultimate gravity grip with the GFR1 Factory. The grip’s features include specific textured siping on the top, added grip zone on the bottom and the factory rubber compound for maximal damping and control through the most demanding tracks. Available in the oil slick version as a FMD Racing Edition.

Slimly formed, maximum damping

Ergon developers work closely with athletes and teams. This is the only way to produce the most efficient products that can meet the highest demands. The GFR1 Factory evolved through close teamwork with top professional downhill riders. One of the most notable features from this relationship is the grips slim design for maximum feedback yet still highly damping as a result of the specific textured siping along the gripping surface area.

Ideal hand position thanks to inner stop

The inner stop of the GFR1 Factory provides direct orientation for fast maneuvers, jumps or tricks. This provides an additional safety feature keeping your hand in the optimum position and ensuring that you can operate the controls at all times.

Reduced effort

Pulling up the front wheel of your bike costs valuable energy every time. In order to minimize the gripping forces, the GFR1 Factory has a particularly strong lower grip zone for the fingers.

UNIQUE GRIP RUBBER – Best quality made in Germany

A special feature of the GFR1 Factory is the unique rubber compound „Factory Custom Rubber“ developed and manufactured in Germany featuring maximal grip and rebound properties. The material meets the highest standards of purity, is TÜV-certified, durable and unique in the world of bicycle grips. The grip feel is soft yet defined and precise. Ergon’s core values of ergonomics, product design and engineering all happen in Germany.

FACTORY CUSTOM RUBBER – Precise durability

A grip is always subject to wear and tear, especially in tough MTB terrain. With the Ergon-exclusive "Factory Custom Rubber" material, the surface structure remains precise and especially grippy for a longer durations of time than a standard rubber.

INTERIOR CLAMPING – One screw – more safety

The strong aluminum inner clamp prevents the GFR1 Factory from twisting on the carbon handlebars. This secure clamping allows for even more safety on the bike!

EXCHANGEABLE END PLUGS – Particularly long-lasting

The end plugs on the GFR1 Factory are replaceable. This adds an important durability feature for the grip.

Comprehensive Guide with Practical Insights
Format: Paperback
This is a solid book for understanding the art and science of working with LLMs and other generative AI models. I always struggled with getting the output I was looking for, and wasn't sure how best to "ask" the models for what I wanted. This book did a great job of laying out the strategies and practical guidance to craft the prompts. There were a lot of tips and tricks, but the overall understanding and framework around prompt engineering has been super useful.

A must read!
Format: Paperback
Hands down, the best book on prompt engineering and implementing LLMs. Really enjoyed Michael and James deep dive. Whether you're technical or not, this book is foundational to a deeper understanding in how to properly explore and implement LLMs.

Helpful for GPT/LangChain framework
Format: Paperback
I applaud the authors for putting forth a comprehensive introduction in a rapidly evolving space. I absorbed a lot, helpful as I was developing a prototype — using open source methods. And that’s where I was disappointed. The LLM and examples are highly adapted to OpenAI’s GPT-x and the bulky LangChain framework, something not obvious until you dig in to the book. Sure, this may be where newbie demand was when the authors began writing. But as the open source models and OpenAI alternatives gain speed (e.g. Llama 3.1, Groq, etc.) this book may quickly need an updated and expanded version to stay relevant.

Good concepts, but uneven depth
Format: Paperback
Some helpful prompt frameworks, but parts felt repetitive and a few sections stayed too high-level for advanced users. Beginners will likely benefit more than experienced practitioners. If you’re new to prompt engineering it’s a decent starting point; if you’re already building structured prompts daily, it may feel light.
