Lighter. Stiffer. Faster. The Ultimate Crank Arm Upgrade.
Experience a tangible performance boost with the Neutron Carbon Crank Arm. Meticulously engineered from full carbon fiber, this crankset is a testament to our obsession with stiffness, low weight, and rider-friendly design. It represents a significant leap forward, offering a 25% increase in stiffness and a 12% reduction in weight over our previous generation.
At a mere 335 grams (for a set of two arms and spindle), the Neutron Crank Arm is the perfect foundation for a featherlight build, providing the rigidity needed for explosive sprints and efficient climbing.
The Neutron Advantage: Designed for the Rider
We focused on the details that matter most to mechanics and discerning cyclists:
•Effortless Installation: Built with a 24mm aluminum spindle and a SRAM 8-bolt mount, installation is straightforward. No proprietary tools or heavy-duty torque wrenches required.
•Seamless Integration: A Q-factor identical to Shimano standards means no need for biomechanical adjustments. It’s a true plug-and-play upgrade.
•Clean & Simple Setup: Forget fumbling with extra spacers. Our design ensures a faster, cleaner, and more precise installation right out of the box.
Build Your Perfect Drivetrain
The Neutron Crank Arm is the versatile heart of your custom setup. Choose your path:
•Power-Ready: Select the SIGEYI AXO power meter spider for world-class, dual-sided power measurement with +/- 1.0% accuracy.
•Power-Optional: Opt for the standard spider and upgrade to a power meter later.
•Pure Lightweight: Choose the "Spider WITHOUT powermeter" option for the absolute lightest configuration.
Tech Specs
•Crank Arm Material: Full Carbon Fiber
•Spindle: 24mm Aluminum
•Mount: SRAM 8-Bolt Direct Mount
•Weight: 335g (L/R arms + spindle)
•Available Arm Lengths: 165mm, 167.5mm, 170mm, 172.5mm

•Chainrings: Compatible with any SRAM 8-bolt direct mount chainring or power meter spider.
The foundation of speed is stiffness and low weight. Build your dream bike starting with the Neutron Crank Arm.

Not the most durable, but it is a quality toy
I bought this as a gift for my friend's mini dachund and I knew she would love it because of the long legs and how soft it is. She loved it alright. So much that she ripped the ear off in the first 10 minutes of having it. It's not durable, given a year old mini weenie can rip it, but it is a good toy for the dogs that don't choose death for every toy they have.

very cute - not for most dogs
Very cute but not made for dogs who carry their toys. I purchase toys such as this every few months because my dog loves to snuggle and play with them. She has many of them and delights in carrying her new ones with her. This is the first stuffed toy that's only lasted a few days. She does not tear into her toys nor is she hard on them. Most of her toys are still intact. The one's that are worn are at least two years old so this was surprising. This toy would be great for a dog that lays still with it, won't carry it and just cuddles. It wouldn't last two seconds with a dog that is hard on their toys.
