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

Amazing Support and Sleep Quality… But the Price Is Hard to Justify
These pillows genuinely surprised me. The best way I can describe them is that they somehow feel soft and firm at the same time. The memory foam is very responsive and almost feels like slime or Play-Doh in the way you can squish and shape it, but it immediately returns back to its original form. They feel premium the moment you touch them. I usually have a slightly hard time falling asleep and tend to toss around for a while before getting comfortable, but with this pillow I fell asleep incredibly fast. I’m not exaggerating when I say it took me less than two minutes the first night I used it. That alone impressed me. The biggest difference for me has been shoulder and neck comfort. I have a weaker right shoulder, and sleeping on that side normally causes discomfort or makes me wake up in pain during the night. With this pillow, I was actually able to sleep on my right side comfortably and woke up without that usual soreness. I also noticed I slept through the night without waking up repeatedly to readjust, which is rare for me. The contour shape definitely helps with alignment. The center cradles your head nicely while the raised edges support your neck well, especially for side sleeping. I can see why some people call these orthopedic pillows. The cooling pillow covers are also really nice. They feel smooth, breathable, and cool against the skin, which made the overall sleep experience feel more comfortable and “high-end.” That said, these pillows are not for everyone. I can understand some of the other reviews mentioning that the shape can feel restrictive if you move around a lot during sleep, or if you prefer a flatter pillow. These are very specifically designed pillows, not the kind you casually fold and bunch up however you want. My only major issue is the price. The pillows themselves are genuinely excellent, but I personally cannot justify spending around $330 for two pillows. I received them through the Amazon program, and while I really do love using them, if I were paying full price with my own money, I probably would not purchase them at that cost. If the price comes down significantly, though, I could absolutely see these being worth it for people dealing with neck or shoulder pain. Overall, the comfort and support are fantastic, and they noticeably improved my sleep quality. My neck and shoulder feel much better in the mornings, which honestly matters more than fancy marketing words ever will. The pillows are great. The pricing department just seems to have taken a very confident nap.

The Pillow Everyone in the House Wants Now
This set was originally for my mom and my daughter, but after trying one myself, I completely understand why they like it so much. In fact, it convinced me that I need to order one for myself as well. The contour design does a great job supporting the neck and head without feeling awkward or overly firm. It feels different from a traditional pillow at first, but after a night of sleep, the extra support becomes easy to appreciate. What stood out most was how rested I felt the next morning. The pillow helped keep my head and neck in a comfortable position throughout the night, whether sleeping on my back or side. My mom immediately noticed the comfort, and my daughter took to hers right away too. It's rare to find a pillow that works well for different ages and sleep styles, but this one seems to have broad appeal. The memory foam feels supportive without being hard, and the cooling cover adds to the overall comfort. The removable cover is also convenient for keeping everything clean and fresh.

The price of $340 for two pillows may be out of reach for many individuals
The price of $340 for two pillows may be out of reach for many individuals. While these pillows provide excellent neck support, they do limit sleeping positions to just one preferred pose. Designed with high-quality ergonomic features, these pillows are double-sided to cater to different comfort needs. The softer side is perfect for those seeking easy relaxation, while the firmer side offers enhanced support for a more restful night's sleep. Crafted from premium memory foam, the supportive contour design promotes a natural sleeping posture, ensuring balanced support whether you sleep on your back or side. Each neck pillow is accompanied by breathable, cooling pillowcases that enhance comfort throughout the night. These cases are also removable and machine washable, making it simple to keep both pillows clean, fresh, and hygienic. Overall, these pillows provide exceptional neck support, helping you relax and enjoy a restorative sleep experience.

BEST PILLOW OUT THERE! Great for back and side sleeping. So glad I found them!
Like a cloud! Really loving this pillow set! I have tried many different pillows trying to get rid of my neck pain to no avail. One of the pillows even had a chiropractor endorsing it - and then I found it was actually causing me jaw pain when I slept on my side because it was too firm and had no give. We are LOVING THIS CERVICAL NECK PILLOW! I have been using it consecutive nights as a back sleeper and side sleeper and my neck continues to feel pain-free, no cricks and when I sleep on my side there is no pressure on my jaw or shoulder pain. It has just enough support in all the right places and enough give in the center to allow my head to comfortably sink into the middle aligning my neck for comfort, and enough give it does not put pressure on my jaw from the side sleeping. It also came with 2 pillow cases that are soft - I love the way it keeps the frizzy of hair from developing around my face because my hair is sliding, rather than friction when I move in my sleep. This pillow is a Win-Win! Getting a set for my son too!

Great Pillows, But Made for Taller People
Clearly these pillows are high end, very well-made pillows that will last for, dare I say, decades, and they are supportive for the neck and spine... for some people. I got the set of two, one for myself and one for my husband. I am 5'4", about 165lbs, and he is 6'2" about 240lbs. So there is a big difference in size between us. The pillows arrived in a very small but high quality box, each rolled separately, and I thought for sure that they would take a while to roll out, fluff up, and unwrinkle, the way our bed and other pillows did. But that wasn't the case at all. These pillows immediately fluffed up and were usable with not a single wrinkle (see photos). The silk gray cases that come with them were also in no way wrinkled and fit like a glove. They were a little difficult to situate for me (the cases) because they must go on a certain way (my husband wants me to tell y'all that he got it right the first time). It took me three tries. But once they were on, they looked beautiful and the pillows felt very soft with them on. Now, that said, it was clear the moment I laid on it that it's made for someone taller, or rather, with a longer neck. When I lay on it, my head does not land on the center of the pillow where the bump is, where it's supposed to cradle my neck. My head instead lays directly on that bump, cocked up with my neck kinked. That's also because *I* am a side sleeper. Now if I lay on my back, my head lays a little more in the center. That is the only way this pillow slightly works for me. If you read the "instructions," it explains that there is a section for your head when you're laying on your back (the center dip) and a section for when you're on your side (the edges). Either way is too high for me. My neck isn't long enough. In order to get it into the correct position, I have to stretch it unnaturally. When I lay naturally, my neck is bent and kinked and hurts more in the morning than ever before. The feel of it, putting aside its side and dimensions, is very soft to the touch but also quite firm at the same time. It's not the kind of memory foam that takes a while to bounce back. It's bounces back immediately. It's very springy. The only way I can use this pillow is if I spin in around to keep the cervical support bump at the top and just lay over the flat portion, making it more like a regular pillow. It's still too high and stiff for me, but it's better. Now for my husband (6'2"), this pillow works great! He's a back sleeper and it really supports his neck. And he does sometimes lay on his side, and apparently it's supports his neck then too. His neck is long enough to reach that edge section for side sleepers and the center supportive dip for back sleepers. He loves it! He says, his neck feels great in the morning and it's his new favorite pillow. When I got this pillow set, it was listed at $340, and he said that it was not worth that price. But it is now listed at $169, and he's saying that is a much more reasonable price. I personally wouldn't pay that, but that's because the pillow doesn't work for me. I stand by my statement that these pillows are for taller people (or people with longer necks). But for him, he would pay it. I wish it worked for me. I'm a bit jealous, to tell you the truth.
