Aspero GRX RX610We may not have made the first gravel bike, but we definitely made the fastest gravel bike. In 2019, spero took the world by storm, heralding a new era of speed in gravel. It was gravel, Cervelo style.

We may not have made the first gravel bike, but we definitely made the fastest gravel bike. In 2019, Áspero took the world by storm, heralding a “new era of speed in gravel.” It was gravel, Cervelo-style. Since then, gravel bikes have grown, fragmented, and started to look a lot like the road and mountain bikes that spawned them, with suspension forks, bolt-ons for…everything, and ever-increasing tire widths.

The new Áspero remains true to those early, simpler days of gravel, but with some improvements—a threaded BB shell, neater cable routing, and a UDH-compatible derailleur hanger for those who want to use SRAM’s Transmission drivetrains. And it’s faster, of course. We shaved off three watts worth of drag in the redesign process. We also dropped the seat stays to give a bit more compliance out back, and reduced front end stiffness slightly to make the last hours of a long race less painful. Between those dropped seat stays, we added in a bit more clearance for mud, too. Aspero will clear a 45mm tire by ISO standards. ISO mandates a minimum of 4mm of clearance between tire and frame in all dimensions, but we’ve found (and we think folks at last year’s unbound will agree) that sometimes you need a bit more than 4mm in muddy conditions. We designed the Aspero around 42mm tires with an additional 3mm of clearance on top of what ISO requires, but if you’re feeling lucky (or your rides are typically dry), feel free to push that to 45mm. It’s a lot of seemingly small improvements, but they add up to a lot. The result is a bike that feels a lot like the original Aspero, but is faster, more comfortable, and more versatile.

FEATURES:

  • T47 Bottom Bracket: Áspero uses the asymmetrical T47a threaded bottom bracket we pioneered on R5-CX. It’s a simple, rider serviceable interface that allows us to deliver the benefits of BBRight in a more user-friendly form.
  • Easily Adjustable Front End: Áspero shares the same bearing dimensions as R5, Soloist, R5-CX, and Caledonia, which means you can use any combination of bearing caps and stems. Want a super-racy, fully internal look? Grab the ST31 and HB13 from R5. 
  • Universal Derailleur Hanger: SRAM made everyone want to step on their derailleurs when they introduced the Transmission mountain bike drivetrains in 2023. It seems unnecessary, no matter who made your derailleur, but Áspero uses the Universal Derailleur Hanger (UDH) standard in case you want to try.

Good-ish
Format: Kindle
🌶️ 0/5 ⭐️ 3/5 I will preface this by saying I am not a huge RH fan. However it didn’t feel like a RH quite yet. The relationships and plot are all building in this book. At first I was thinking things were happening stupid fast since she’s had zero interaction with another being and has been tortured her whole life, and I believe they were for one side of the relationship, but by 50% things moved too slow lol. Idk I think the main 1-3 guys I’m actually interested in more than the others didn’t get enough air time so I hope the next book things start moving with them since it ended the way it did.

Can I have Term 2 now?
Format: Kindle
This is by far my favorite book of Lyra's to date. I gobbled this book up so fast, I was so upset I finished it. I know this is going to be a book I reread, just like Fate Hollow Academy. I loved Fate Hollow Academy, so I was excited when Lyra announced she was taking us readers back to Kalista. Although the characters from Fate Hollow are mentioned several times throughout the book, this book is about Pandora and her love interests in the Demon Realm. Before you deep dive into this book, definitely look at the trigger warnings before you start. When Lyra says there's dark themes in this book, she meant it. Also, just know this book does end on a cliffhanger and will probably leave you with as many questions as it did me. Below may contain some minor spoilers, so keep that in mind if you want to keep reading my review. Pandora's first 2 decades of her life are full of torture, hatred, and confinement in a cellar. That is until her father finds her and brings her into the world she was supposed to live in. Because of her upbringing she wasn't acclimated to the Demon world and the way their society works so when she is offered the chance to go to a Demon Reform Accademy, she accepts it to learn the ways of society and how she is supposed to feed. Pandora isn't like the other common demons in this world, no. She, like her father Death, are soul-eaters. Pandora is too scared to release her powers because she doesn't want to kill anyone, so she needs to learn how to feed off of a piece of soul instead of taking the whole thing. Because of who her father is, she's classed as a Noble, and while she doesn't agree with her fellow Noble students, who look down on the "lower" class, she also is faced with 3 Demons who hate her for being a Noble. Theses a lot of back and forth tension which these 3 demons who have issues of their own. One is obsessed with her, and wants to know all of her secrets. One leaks fear all over the place, but also is scared of the "princess" -wink- -wink-. One is a complete drunk who doesn't like her just because he's got family Noble problems. Don't worry, there are 2 other demons who are just the sweetest towards her. One who will get vengeance for anything done to her, he's got Golden Retriever energy around her and touch her and die energy for anyone around her. Finally, there is one who is friends with her even when the whole school is scared of her, who brings her into his dreams and will create nightmares for those who bother her.

This was more than I expected...
Format: Kindle
So...I finished this book at nearly 2am! It was just that hard to put down. I loved that it's set in the same world as Fates Hollow but in the future. Poor Pandora has been through so much but there's light at the end of the tunnel for her. She finally meets her dad and it turns out he's amazing. In order to help her learn about demon society and how to control her magic he sends her to the Demon Reform Academy. There she meets 2 awesome demons who help her and care for her. She also sadly meets her 3 tormentors. I will say though that while they do bully Pandora they also rescue her several times and defend her. They too have traumatizing pasts and can't see the good that is in front of them. Of course demon society needs to be shaken up too since that's part of the problem. I really enjoyed this read. I teared up a few times throughout the book but I liked the characters and that ending...well it looks like 3 in denial are going to need to grovel hard.

MUST READ BOOK!!
Format: Kindle
I was in a huge reading slump, when one of my favorite authors recommended this book in her readers group (The amazing Marie Mistry 🫶) and I absolutely DEVOURED this book. Now I’m in the club crying about having to wait until December for Term 2! This book is about a girl named Pandora who has suffered a life that nobody would ever wish to have. This book is about Pandora learning how to live, learning about herself and what she really wants. She has a long journey to find out all of these things, but she took the first steps in this book and it was beautiful to read. Some of the men in this book are our dream men, Hunter and Reed 😍 and then we have the men who need some work and who we all really just want to beat up until they admit what they really feel, Skel, Bram and Dexter. But that cliffy was a killer and I absolutely cannot wait until the next book!! You have written an absolute dream of a book Lyra and I eagerly await the next installment in this series!!!

Monstrously Sweet
Format: Kindle
This book packs an emotional punch, especially if you’ve experienced childhood trauma (particularly abuse and/or neglect). Alexandra creates these three strong protectors who love her and will do anything to make her feel happy and safe. She started out drawing them when she was a small child, and then transitioned to stories as she grew up. Lucien, Elwin, and Kylo look frightening in their monster forms, but it’s clear that they would never hurt Alexandra, and she has never felt afraid of them. They have very distinct personalities that we get to know better throughout the book. The love and devotion they have for Alexandra is sweet and unwavering. This is a fantastic and creative story! The world-building is wonderful - it’s a shared world with M. Sinclair, and takes place at a university for supernatural beings. The additional world-building within Alexandra’s story added even more depth and intrigue. The spicy times were 🥵 and it’s more of a medium burn, but it works with the characters and I expect that it’ll pick up quite a bit in the next books. Monsters Within has a unique way of addressing mental health issues that can come from being abused and neglected. There are some flashbacks to Alexandra’s childhood that provide some insight but they don’t go into heavy details. I absolutely adored this book and can’t wait for more!
