Shimano RS510 Chainset
Sleek and efficient, the Shimano FC-RS510 Double Chainset grants performance to any CX, road or gravel bike using an 11-speed gear setup by being fully compatible with both 135mm or 142mm spaced rear dropouts, enabling optimal use with either rim or disc brake frame configurations.
The anodised crank arms offer a smart silhouette, keep the weight to a minimum and grant excellent pedalling efficiency, even during high power sprints and climbs. The drive side crank arm is mated to the oversized, 24mm diameter axle via a seamless, two-piece design to heighten rigidity and strength. This oversize axle configuration permits larger bottom bracket bearings (available separately) that are more efficient and durable.
Lightweight aluminium chainrings have chamfered teeth profiles to improve gear shifting markedly and provide silent running through even the most gritty conditions. The spacing of these chainrings is specifically formatted to work perfectly with bikes that have either 135mm or 142mm rear axle spacing. This chainring spacing also accommodates shorter chainstays.

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.

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.
