Ruote Fulcrum Speed 55 DB
Il nuovo profilo del cerchio che caratterizza la Speed 55 DB è un ulteriore passo avanti nella ricerca della miglior resa aerodinamica, un modello quindi orientato ad un pubblico esigente e “corsaiolo”. Per migliorare la resistenza al rotolamento (e quindi la velocità) del sistema ruota/copertura abbiamo progettato questo modello nella versione 2-WAY FIT.
Il metodo di produzione del cerchio in fibra di carbonio privo di fori nel canale interno – tecnologia costruttiva brevettata permette inoltre una costruzione più forte e robusta in grado di sfidare anche le condizioni di gara più estreme. La larghezza del cerchio di 19 mm si sposa perfettamente con il trend di utilizzare coperture sempre più ampie, una scelta che migliora ulteriormente la resa aerodinamica del sistema ruota/copertura. Questi dati sono stati validati da studi e test intensivi in galleria del vento dove svolgiamo regolarmente i test sui nuovi progetti. Speed si è dimostrata la migliore opzione in termini di indici di penetrazione aerodinamica della gamma Fulcrum e prende le indicazioni dai profili sviluppati nella versione tubolare per i team World Tour.
Le Speed però non rispondono solo alla resa aerodinamica, per ottimizzare la prestazione le ruote devono essere anche leggere e scorrevoli, la bilancia si ferma a 1580 grammi mentre per i cuscinetti abbiamo scelto componenti USB ceramici.

A fun and entertaining escape room mystery
Format: Hardcover
I had a lot of fun following the team as they get to know each other and solve the complicated mysteries of the escape room. As the story progresses we find out the real reasons why they all wanted to compete on the TV show, and as they get to know each other better they are able to really become a unit in solving not only the escape room, but work together to find out what really happened to Alicia last season.
The mystery was good, I definitely didn't figure out what was going to happen or who was ultimately behind everything coming.
This is a fun, fast, and very entertaining read. And I think with the escape room aspect it would make a really a great movie or TV show.

Amazing book
Format: Hardcover
Amazing book. The plot twist at the end totally surprised me. The characters are so well written and I had so much fun going on a journey with them. The characters seemed to jump out of the book and the feelings and actions seemed very much like teenage actions. As an escape room lover I loved at the puzzles the teens had to solve along the way. I can't wait to see what happens next.

Great YA Thriller
Format: Audiobook
I thought this book was well written and fast paced. Everything you want in a good thriller. It was written exactly like a dramatic reality show and it kept you guessing until the end. It was a quick fun read if you are in the mood for a reality show that has the feeling of clue and and escape room all in one.

Exciting YA adventure
Format: Hardcover
📚 Do you find yourself shouting answers at game shows? Have you ever braved an escape room? Or maybe you’re just a sucker for a book with stenciled edges? If you answered "yes" to any of the above, I invite you to step into this original YA murder mystery.
The plot follows a team of teenage contestants navigating an escape-room-themed reality show through, puzzles, sabotage, betrayal, and... murder.
💭 I showed up for the pretty book cover, but stayed for the cleverness of the plot. It was suspenseful, entertaining, and very educational! I think adults and teens alike will get a kick out of the riddles woven throughout the story.
The characters were such a highlight for me. Watching four complete strangers transform into a close-knit team over the course of the season was so fun. Friendship, loyalty, and trust are the heart of the book, but there’s also plenty of romance, crime, and amateur sleuthing. I was hoping for a slightly different direction for the finale, but it was still an unexpected, action-packed ending.
⚖️ All in all, the story inside was just as good as the "pretty book" aesthetic on the outside. This was an exciting, fresh YA mystery. 4/5 ⭐ from me!
