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.

Don’t order from this company if you need your things in a few days, I ordered prime almost 4 days ago and it’s now saying it’s delayed until July 5th… WTH! I should’ve been told sooner so I could buy from another company

Doesn’t stink, not super thick and minimal white cast
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
The product is a lot thinner than other sunblocks. VERY creamy! The tint is sheer but it’s less sheer than I actually thought. Which is fine bc I’ll use it as more natural makeup in the summer time if I go anywhere. It’s not so much that you can tell either though! My sister who sees me every single day told me my skin looked “very youthful” today and didn’t know it was tinted spf. She had smelled my face when I wore another spf and had agreed the other one STUNK so badly but we didn’t smell anything on this one. I am fairly light but I got the medium based on reviews I searched for on tiktok. I figured the white cast would lighten it up somehow but there is NO WHITE CAST! But the color is still fine bc it isn’t chalky like la Roche posay tinted liquid spf. This is very natural! When I applied this product it looked SO SHINY. I almost regretted it…. But 20-30 min later (I applied it then immediately drove 15 min to my sisters house) the product had set and it has a much more natural and dewy but not crazy oily finish. I love it so far. I do consider myself to have very sensitive dry/combo skin and am in the process of repairing a damaged skin barrier. This didn’t itch or burn or anything. I did notice it started pulling after rubbing it in so much but I did kinda rush my morning routine this morning. I’ll update if it wasn’t my bad. Update: it’s been 5 hrs since I applied it. It’s definitely not going to be doubling as a moisturizer. I don’t feel like it’s dehydrated but it’s not moisturizing like other sun screen has been. But maybe just expected it to since it’s cerave but it’s not marketed as such. But that’s ok with me bc I’m more worried about the SPF part of the product. Shade: at first I didn’t notice bc I was just indoors…. But it has enough tint for someone to notice the change in skin tone between my face and body so now I’m going to need to order the light one

Outstanding sunscreen.
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
I just ordered my second bottle of this sunscreen. I live in Florida so sunscreen is a big necessity. Love it. The little tint is perfect and it feels great. It is not overly greasy. I do apply a little powder and a little blush then I’m on my way out the door. I highly recommend this product.

The perfect summer tint with SPF protection
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
I am really enjoying this CeraVe Hydrating Mineral Sunscreen! I am always on the hunt for products that give me a quick, healthy glow without having to put on a full face of makeup, especially during the summer, and this completely hits the mark for easy coverage. ​The texture is beautifully lightweight and glides on so smoothly. I was honestly a bit nervous that it would leave that heavy, sticky, suffocating feeling that so many sunscreens do, but it is completely non-greasy. Plus, a huge win for me is that after wearing it for hours, it doesn't migrate or burn my eyes at all. ​The only reason I'm knocking off one star is the shade range. I picked up the Medium tint, and while I can definitely make it work for the summer when I have a bit more color, I really wish they offered an "in-between" shade option between Light and Medium. ​If you're looking for a comfortable, daily SPF that lets your skin breathe while evening out your complexion, this is a fantastic staple to have in your routine!

This really works!
Style: SPF 50, Size: 1 Count (Pack of 1)
A week on the beach and no burns! It is a little hard to get rubbed in and I probably had a little bit of a white cast on my skin. So worth it though for the protection of me and the reefs.
