* This is a limited release of 20 units. Once they are gone, they are gone. *

Imagine transforming your Stumpjumper into a whole new beast—ever wondered what it’d be like if it sported a rearward axle path and an idler? Wonder no more. This kit does exactly what the name implies: it converts your Stumpjumper into a high-pivot, chunder-devouring monster. By creating a reward axle path, it helps the wheel sail over square-edged impacts effortlessly, sending less shock through to you. And the numbers don't lie. Our tests show a significant reduction in vibrations at the bottom bracket, meaning smoother, more controlled rides.

In its stock form, the axle shifts rearward to around -2mm at sag, then pushes forward to +14mm at the bottom of the travel. But with our conversion, things get wild. The axle moves a massive -12mm rearward at 60% of travel, and by the end, it sits a whopping 21mm further back than the stock position. Yes, you read that right—21mm.

To make sure pedaling efficiency stays sharp without sacrificing comfort, we’ve introduced an idler that keeps chain growth in check. Compared to the stock setup, this means 25% less pedal feedback at the top of travel and, an even more impressive, 70% less at the bottom. The high-pivot design naturally gives you anti-squat, meaning you don’t have to rely on chain tension to fight against bob. The result? Smoother, more efficient riding without the usual compromises.

Attention to detail was the name of the game with this kit. It features touches such as sleek routing for the brake line that cleanly routes it inside the chainstay with a cover and a custom chainstay protector. Each part was meticulously machined at there are a lot of them.

Fluffy and Nice Omegaverse
Format: Kindle
… this would have made 5 stars but for 2 reasons. A.) there were quite a few typos; misspelled words, missing quotations, “the his” mistakes, and various signs that maybe a proofread would do good. B.) the writing was quite textbook. Late blooming omega is struggling with her new self, finds a absurdly wealthy pack of alphas, every thing is almost insta-love but she resists, then decides to love herself and let everyone be happy. Rian was my favourite (obviously the author’s favourite too because he got the most page time) but I wish we could see more of his CEO side? He went to work maybe ONCE the entire time. Gray was supposed to be the “growly one” but he turned out to be puppy dog. Lucas was a genius brainiac doctor - but also super alpha with an aggressive hindbrain with a breeding k*nk?? And then there was no actual “breeding”?? Spice 3/5 - normally omegaverse books are super high on messy smut but this was tamer. Romance 3/5 - insta-love that was then resisted because of personal hangup’s Plot 2/5 - weird paced head hopping, showing the same scene from different POV’s that made me feel like it was 2 steps backward, 1 step forward. Humour 4/5 - there were a dozen lines that genuinely made me chuckle out loud Would have been five stars but the lack of proofreading and the predictable plot made me unable to get up to ADORED IT level - four stars is still and official ENJOYED IT, y’all. This isn’t a bad rating. The “Club Heat” has intriguing possibilities so I’m going to give the second one a shot.

I already bought part two so I’m going to be reading that in between work phone calls!!!! DON’T TELL MY BOSS 😂😂😂😂

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.
