Road Reimagined
Go long, go short, go fast. This is WorldTour performance for real world rides.

Ride Confident
More visibility, more awareness, more integration, with our next-gen SmartSense system. All running from a single concealed battery. Intelligent lights adapt to let other road users know you’re there. While the rear-facing Garmin radar keeps you switched on to approaching traffic. Letting you ride the bike that’s up for anything, whatever time of day or night.
Radar
The rear radar watches your back, alerting you to approaching vehicles so you can ride with ease.
Lights
The headlight is small yet powerful, turning night into day with up to 800 lumens. A daylight function keeps you safe, while its stem-mounted design keeps the cockpit clean.
Battery
Neatly integrated into the downtube, the battery powers lights, radar, and shifting, providing up to 24 hours in flashing mode or over 12 hours in steady mode.
Compliant Comfort
With advancements in our carbon layup, our engineers have made the new Synapse 20% more compliant than its already butter-smooth predecessor, ensuring you feel 100% more comfortable even on the roughest roads.
Like A Glove
A great fit and feel makes for a great ride. And with our Proportional Response Construction, every rider gets that as standard. From the carbon layup through to the geometry, everything on Synapse has been tuned and tested by frame size. So that your bike works in harmony with you to give the best possible ride for you and your height.
Bring it all, bring it on
Our all-new StashPort storage system in the downtube is there when you need it and hidden when you don’t. Paired with its StashBag buddy, you can bring along your ride essentials and know that they’ll be secure, whatever you get up to out there. Meanwhile, best-in-class tire clearance lets you take the idea of riding for longer to a whole new level.
Real World Performance
Designed to go fast, built to go long, and made to keep you comfortable, the Synapse redefines road performance. With a lightweight frame featuring wind-tunnel-sculpted tubing and PB-blasting stiffness-to-weight, it’s a bike that’s ready for anything you demand of it. Just ask Lachlan Morton why he trusted it for his record-smashing lap of Australia. Unreal speed, engineered for real-world roads.

Nothing ordinary about it…
I bought this for my 14 year old niece for Christmas and it was a big hit. Apparently The Ordinary is on all of my nieces’ Amazon wish lists, and I have no shortage of nieces. I see it pop up every time I check their lists for birthdays, Christmas, graduations, and every other buying holiday in between. When you’re a teenager, having clear, fresh looking skin is basically a top priority, and she was really excited to start using these. She’s been experimenting with different skincare lately, and so far this is the only brand that hasn’t caused her to break out, which is a pretty big win at 14. She said it feels light on the skin and leaves her face feeling clean and hydrated without being heavy or sticky.
And honestly, there’s nothing ordinary about this stuff except the name. It’s a great little starter set for someone getting into skincare, and judging by the reaction I got when she opened it, it also earned me favorite aunt status, which I’ll gladly take.

It's great for food delivery and driver jobs
Size: 7''x3''
My husband got this for food deliveries and uber/Lyft. The app let him add several texts. I believe he added 4. He was able to design it how he wanted it. It seemed fairly easy and I liked how it looked. The words would scroll over, like... Uber eats, etc... It included a big roll of strong red tape. The led screen product is charged by wall plug, phone, or the car usb phone charger. I think it was a spectacular product. I thought it was limited to 4 letters since it is small in size.

Very good LED sign for cars, studios, desks, etc
Size: 1PCS 15''x4''
Great! Item really stands out. This LED sign by Ray home features way more than just devil eyes. There's a lot of pre-built templates for every gig work there is out there for your car. Item was described. A bit dim during the day but at night really shines stands out. You can customize it with uploads withdrawing. You can have programs that animate between the different signage. It's a great product for a car or for your home. To be honest, I can see a lot of uses for this. High quality design. Easy to work app. The adhesive is great for glass. It's reusable plus it comes with strips. If you want to mount it permanently not on glass. Overall a great deal.
