Highlights

12 FUNCTIONS w/ OPTIONAL CADENCE SENSOR: BC 12.0 WL displays trip distance, speed, total distance, trip time, clock, total trip time, average speed, average speed comparison, maximum speed, and current temperature. It also provides monthly statistics and can be used with two different bikes. 12.0 WL ATS can be paired with optional cadence sensor available as separate accessory for the basic ATS computer, included in ATS CAD. Languages: English, German, French, Italian, Spanish, Dutch, or Polish.

WIRELESS DATA TRANSFER & LARGE BACKLIT DISPLAY: The wireless (WL) encoded transmission SIGMA has developed eliminates the need for cables. A wireless transmitter on the fork continuously measures and transmits bicycle speed without interference to the BC 12.0 WL's receiver. The 31 x 41 mm display has room for large numbers that are very easy to read during a ride. Especially practical is the BC 12.0 WL backlight, so the values can be read easily even when it is dark.

WEATHERPROOF, WITH LONG BATTERY LIFE: The BC 12.0 WL is water-resistant and weatherproof. The integrated, replaceable button battery (CR 2032) is sufficient to supply the BC 12.0 WL with energy for well over two years. During battery replacement, all total values and settings remain protected. The pre-defined tire sizes, ranging from a small child's bike to a 29" bike, make it easy to set the BC 12.0 WL. You can also enter the tire circumference exactly to the millimeter.

QUICK MOUNTING & EASY OPERATION: The BC 12.0 WL's handlebar bracket and speed sensor can be mounted quickly on the bike with cable ties (included). The bike computer is convenient to remove and store at any time. The wireless bike speedometer can be operated easily and intuitively with its three buttons. The two lower buttons allow convenient toggling among individual functions. The menu button takes the user to the settings and monthly statistics. 

VARIABLE MOUNTING OPTIONS: The BC 12.0 can also be used with the SIGMA OVERCLAMP BUTLER or LONG BUTLER handlebar bracket, available separately as accessories for handlebars with diameters of 25.4 or 31.8 mm. The OVERCLAMP BUTLER provides more space and order on the handlebars and a great view of the bike computer. The LONG BUTLER positions the bike computer away from the handlebars and encourages an athletic posture. There is option to fix with an additional screw to prevent theft.

Sporty statistician

Whether cyclists are commuting to the office, enjoying a long weekend tour, or speeding along with a road bike, the BC 12.0 WL is the ideal companion for all cycling adventures. This SIGMA ORIGINAL likes things sporty and versatile: the BC 12.0 WL provides cyclists with access to twelve functions, giving them an overview of their performance on two different bikes at all times. The wireless bike computer also provides monthly performance statistics. It is a true SIGMA ORIGINAL with lots of sophisticated functions!

Current speed is displayed continuously, and any value can be chosen as the second value. Slim design and angular shape look good, especially on a sporty bike. 

Those travelling outdoors want to know what the weather will be like. The BC 12.0 WL has an integrated thermometer displaying the current temperature. The wireless bike computer shows cyclists their personal statistics for the past twelve months. Total distance and trip time can be viewed. This “training diary” allows comparison of monthly activity.

The BC 12.0 WL can easily be mounted on a second bike, whether that bike be a road bike, city bike, or racing bike. After it is set up once, the BC 12.0 automatically detects which bike is being used. All that is needed to mount the bike computer on a second bike is a second bracket and transmitter.

What's included: Bike computer (including battery), bracket for wireless model, STS transmitter (including battery), magnet, mounting material, operating instructions

Excellent Hard Sci-Fi… Until the Politics Pull You Out
Format: Kindle
I was really excited to dive into Project Hail Mary. As a longtime Isaac Asimov fan, I’ve been craving fresh, modern hard science fiction that actually respects the science. This book delivered — at least for a while. The author injects real science into the story in a way that’s both fun and fantastic. You don’t need to be an engineer to follow it; a solid high-school education is plenty. The concepts stretch your imagination without ever feeling impossible, and for the first chunk of the book I was hooked. I genuinely thought I’d found a new favorite author. Then the jarring interruptions started. Out of nowhere you get yanked out of the immersive sci-fi world by modern political pandering that feels completely unnecessary. A random parenthetical about Columbus “discovering an already inhabited world” when comparing something to the New World. Casual pronoun lectures. Characters selected or described by race and identity in ways that scream “check the boxes.” These moments don’t serve the story — they feel injected. Once you notice the author’s leanings, it becomes hard to unsee. Each time it happens, the fantasy evaporates. It takes several chapters to sink back into the story… only for the next micro-lecture to pull you right back out. Overall, I loved the writing, the hard science, and the imagination. It’s some of the best sci-fi I’ve read in years. I just wish the author had trusted the story instead of sneaking in real-world politics. It’s like eating the best meal of your life… and then finding a hair or two in it. Strongly recommended for the sci-fi, with the above caveat.

Engrossing and Thought-Provoking
Format: Hardcover
This is an absolutely engrossing read in the first half of the book, especially--so much so that I actually canceled a social plan so that I could keep reading. The author shifts effortlessly across scenes and time--the play of past and present is very much part of the book's plot and insight--and I developed a fast curiosity and unsettling investment in understanding our anti-heroine/heroine Natalie. This surprised me, because had a friend not recommended the novel I never would have signed on to spend time in the head of a "tradwife." For me the novel was an imagined and imaginative provocation on American womanhood (and masculinity) in the 21st century, where no options or "performances" seem entirely satisfying or even real. I found it simultaneously disturbing and darkly humorous, especially in its depiction of young women's collegiate lives. However, readers should have some tolerance for caricature throughout. While I howled at the depictions of the miserable lives of aspiring "modern" women in the dorms and figuratively pounded my fists at the hypocrisy of the tradwife, I was also conscious of hyperbole and exaggeration--no, their lives aren't that bad; nor, I would guess, are the "tradwives" as bad as Natalie, who is a profoundly unlikable character. I did find that the novel bogged down in its middle and late-middle chapters--the mystery of what's happening to Natalie remains but the momentum seems to stall out into repetition. I also felt that the ending seemed too rushed and too tidy, given the nuance we see earlier in the novel. It ends with what feels like a reductive endorsement of modern (or post-modern) life for women when, earlier in the novel, we get to contemplate the flaws in ALL of the scripts and performances that women--and the hapless Caleb-- are asked to live by, or choose... Indeed, the characters that I would have loved to hear more from are the two who seemed more grounded and, ultimately, perhaps happier than the others: Natalie's sister and even her mother... The concluding exposition felt rushed, as did the analysis, in other words...Some of the religious scenes seemed tone-deaf to me... I'm not an evangelical, but Natalie's relationship to God strained credulity. **Highly recommend** this to anyone looking for a provocative and engrossing read on women's lives and constraints in the age of social media that engages in a fascinating thought experiment along the way...

An unexpected reading experience!
Format: Hardcover
Very unexpected novel! I went into it without any knowledge or prior information of what it was going to be about. Main character is not a person you would want to be friends. So when calamities happen to her it was hard for me to muster up much sympathy or compassion. It was more of “you had this coming, you deserve every miserable minute”. And boy, there were many! Some harder to believe than others. As I was reading, I first thought- I don’t want to keep this book, it’s not worth saving. But it developed to be definitely the type of story that sticks in your mind, you find yourself revisiting parts and characters and wondering why that happened and why did that person react a certain way. And to me that’s a book worth reading and keeping on my limited bookshelf. So I changed my opinion as I read to the end of the novel. It is certainly a book worthy of a neighborhood book group discussion. I am recommending and sharing my copy to family members and reading friends.

Beneath the perfect surface
Format: Kindle
Yesteryear completely caught me off guard in the best possible way. What begins as a fascinating look into social media influence, curated perfection, and historical living slowly unfolds into something far deeper and far more emotional than I expected. The storytelling was incredibly well done, especially the way the author balanced the polished modern influencer world against the harsh realities of 1800s frontier life. The transitions between timelines and perspectives were seamless, and by the end, every piece fit together in a way that completely redefined the story. What made this especially compelling for me was how layered Natalie’s character felt. Her upbringing, family expectations, faith, public image, and the pressure to maintain perfection all shaped the choices she made throughout the story. Rather than feeling one-dimensional, she felt like someone slowly buckling under the weight of everything she believed she was supposed to be. The emotional impact of this book surprised me. Beneath the historical elements and social media commentary is a story about identity, appearances, family, and the toll that constant performance can take on a person and those around them. This is one of those books where the less you know going in, the better the experience will be. I expected an entertaining premise, but I ended up with a story that lingered long after I finished the final page.

About that twist…
Format: Kindle
SPOILER ALERT! The thing about big, improbable twists in stories is that the less time you have to think about them, the better their effect. For fans of the classic TV show The Twilight Zone, it has always been clear that the half-hour shows were far better and far more punchy and memorable than their rather sad hour-long cousins. And a book has far, far more time to contemplate a twist than a TV show. Unfortunately, despite some pointed observations by the author (narcissistic people are pretty much unlikable, cruelty and brutality give power to weak men, abused children very often cling to their abusers), the big, improbable twist in Yesteryear almost completely sinks the story. The twist is the same one that sank M. Night Shyamalan’s 2004 movie The Village, and it fares no better here. Yes, people can and do live off the grid. But avoiding every single sign of civilization for years on end? Even if you’re not in a commercial flight path, there are such things as helicopters and small private planes, especially in remote areas. Perhaps people rarely stray onto private land in the wilderness, but once in a while, stray they do. And when that wilderness home was once widely publicized? Excuse me, but people are going to look for it. This is all not to say that Yesteryear was not entertaining - it was. I read it in one sitting. The characters, as unlikable and unreliable as they are, were well drawn. A couple of the children were also quite believable, but the author’s excuse for the rest of the kids being cyphers was that their mother saw them as cyphers as well. Okay, that’s fair, but knowing them better would have enhanced the story for the reader. This is certainly a promising book. It held my attention and was very well-written. But that twist - well, it sank M. Night Shyamalan, too.
