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.

At this rate, I'm leaving this to my kids in my will
Size: 19 Ounce (Pack of 1)
Ten months in and I have barely made a dent in this tub. I am genuinely starting to consider my options — mixing it into smoothies, using it as a cooking fat, applying it to every surface in the house. Something has to be done because at the current rate of consumption this container will outlive me. In all seriousness, the value proposition here is almost absurd. CeraVe Moisturizing Cream is a legitimately great product — dermatologist recommended, ceramides, hyaluronic acid, fragrance free, non-comedogenic, works on face and body, gentle enough for sensitive skin. It does everything a moisturizer should do without irritating your skin or smelling like you bathed in a candle. The 19oz tub is the right call if you actually plan to use moisturizer regularly. A little goes a long way, which is both the best and most frustrating thing about it. Best because you're getting incredible value per ounce. Frustrating because you will be looking at this same tub for the foreseeable future with no end in sight. Great product, generational quantity. Buy it once, pass it down. One star deducted because I now have to figure out what to do with the remaining 18.5 ounces.

Switched from luxury brands and never looked back!
Size: 19 Ounce (Pack of 1)
I used to spend way too much on high end body moisturizers thinking the price meant better results. Tried CeraVe on a whim and realized I was paying for packaging and fragrance this whole time. This does more for my skin than anything I used before. I use it daily all over my body after showering and my skin stays soft the entire day. No irritation ever. The formula is so gentle that I forget I'm even wearing anything. No fragrance, no stinging, no breakouts. Just clean hydration. If you have sensitive skin and you're nervous about trying something new, this is about as safe as it gets. The 19 oz tub lasts a long time even with daily full body use. Ceramides and hyaluronic acid at this price point is honestly ridiculous value. Save your money on the luxury stuff and just get this.

So Far, Really Good for Dry and Sensitive Skin
Size: 8 Ounce, Size: 8 Ounce
I’ve only been using this moisturizer for about 2 weeks, but so far I really like it. It keeps my skin feeling hydrated throughout the day without feeling greasy or heavy. The texture is smooth, absorbs nicely, and doesn’t irritate my skin at all. I also noticed my skin feels softer and less dry since I started using it. It’s simple, gentle, and works well for everyday use, especially if you have sensitive skin. So far I haven’t experienced any breakouts or strong fragrance issues, which I appreciate. Too early to say long-term results, but my first impression has been very positive and I would buy it again.

Gentle but effective
Size: 4 Fl Oz
I’ve used quite a few exfoliating products over the years, but I keep coming back to this one because blackheads seem determined to make themselves at home in my pores. No matter how consistent I am with the rest of my skincare routine, they always find a way to show up, especially around my nose and chin. What I like most about this exfoliant is that it works without feeling harsh. It has a lightweight liquid texture that applies easily and absorbs quickly. Unlike physical scrubs that can leave my skin feeling irritated or over-exfoliated, this provides gentle chemical exfoliation with none of the rough scrubbing. My skin feels smoother after use, and I don’t get the tight, stripped feeling that some acne-focused products can cause. After using it regularly, I notice fewer clogged pores and a visible reduction in blackheads. My pores also look less noticeable, and my skin texture appears more even overall. It helps keep congestion under control before it turns into larger blemishes, which is a big reason why it has remained a staple in my routine. For me, this is one of those rare products that manages to be both effective and gentle at the same time. If blackheads and clogged pores are an ongoing battle, this has been one of the most reliable products I’ve found for keeping them under control while still being comfortable enough for regular use. Summary: This exfoliant has earned a permanent spot in my skincare routine. It helps reduce blackheads, keeps my pores looking clearer, and improves overall skin texture without irritating my skin. For anyone dealing with persistent pore congestion, it’s easy to see why this product has such a loyal following.
