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.

•Pure Lightweight: Choose the "Spider WITHOUT powermeter" option for the absolute lightest configuration.

oh wow
Format: Kindle
I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Wow.
Format: Kindle
Okay I’m usually not one for stand-alone’s I’m an avid series reader but my goodness am I so happy I read this! This story was brilliant & so absolutely mesmerizing. I loved reading about each character and their struggles as well as what helped them to move forward. The ending definitely brought tears to my eyes so hard. I truly wasn’t expecting some of what happened in this story. There is about to be a spoiler I am going to reveal so please stop reading if you don’t want the spoiler !!!! ⚠️ ⛔️ ‼️
I loved that the author didn’t do what most authors do with irredeemable male characters. I truly was hoping that Nate Jr. would be apart of the pack after the way he treated Astrea bc he truly didn’t deserve it. Though I must say you did a wonderful job or redeeming him as a person. I cried my eyes out when he walked into the story. I was truly terrified he was going to be a bad guy to the end. However you truly did him such a justice by having him realize his faults & having him redeem himself in the most wonderful way. I’m so sad that he didn’t get to hear how much his brother loved him & forgave him before dying. But again you wrote that ending so beautifully & I just can’t express how much I loved this story & how you took a different route than most authors I have read have. You are a remarkable author Cinder Blaze & I thank you generously for creating such a masterpiece.

Omegaverse
Format: Kindle
I was pleasantly surprised by this omega verse book. This 1 definitely had a few new twists And I really enjoyed reading it. The main female character was a badass and awesome. She had 1 best friend I wish we could have seen a little bit more of their friendship in this book. Her relationship with the male characters was good not to contrived or super instantaneous. And we had some fun plot twists that I didn't expect. I wish we had more of a follow up on the situation with her family her background and her mother who was a wench. I would definitely recommend this book.

Wow. Just wow. An amazing read
Format: Kindle
This book was eloquently written, or should I say the authors writing style is very eloquent? I loved the characters, and the story was quite compelling. I absolutely loved the FMC, she's a BA who doesn't take any crap & gives as good as she gets. A certain person certainly got his just desserts & then some, the earlier scenes of which were quite satisfying, had me punching the air & everything haha. All in all 20/10, great read

My opinion
Format: Kindle
Let me preface this by saying I really liked the story and the characters however, this book is in desperate need of some sort of editing. It's not misspelled words or formatting, but continuous run on sentences. Redundancies within the sentences. There were a couple of paragraphs that I had to go back and reread 3 or 4 times. Overall, I'd say it was worth the read.
