Road Reimagined

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

Model Description

The all-rounder that’s anything but average. With SRAM’s crisp-shifting wireless electronic Rival AXS 2x, SmartSense Gen 2 visibility and awareness tech, and the Synapse’s legendary ride quality, this one’s engineered to disappear beneath you—until you need it most. Whether the sun’s setting or the pace is rising, it keeps you alert, lit, and in command. Call it modern endurance with eyes in the back of its head and plenty of watts in reserve.

What it's for

Comfortable high-performance road riding, long distance missions, fast group rides

  • Lightweight, smoothly compliant, sleekly aero Synapse carbon frameset with StashPort downtube storage
  • SmartSense Gen 2 - Enhanced visibility and awareness from the sleekly integrated system of lights and radar
  • SRAM's workhorse Rival AXS group - precise, reliable wireless electronic shifting
  • Powerful, controllable braking from SRAM Rival hydraulic disc brakes

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.

Feels good, smells not so good.
Scent: Lavender, Size: 3.3 Fl Oz (Pack of 1)
My favorite lavender hand cream doubled in price, so I looked for an alternative and settled on this one. JR Watkins is a well-established name with a reputation for quality. The cream is nice, but I'm not fond of the scent. There are many different kinds of lavender, and this one is not my favorite.

True Lavender Scent
Scent: Lavender, Size: 3.3 Fl Oz (Pack of 1)
Good quality cream. Nice fragrance - true lavender scent. Non-greasy. I like the flip top cap - easy to use and handy in the car.

Absolutely love this hand cream!
Scent: Lemon Cream, Size: 3.3 Ounce (Pack of 1)
I have really dry skin, partly because I take a chemo med for autoimmune issues that really dehydrated me no matter how much water I drink. Other lotions I bought were either too greasy and just sat on the surface of my skin OR simply weren’t hydrating enough. But this hand cream is my absolute favorite now. It is super moisturizing, but is also fully absorbed by my skin very quickly. It’s honestly impressive. There was a nearly immediate, extremely noticeable difference in the condition of my skin after I started using this. This lotion even seemed to solve a related issue I was having where my dead skin cells just refused to be shed, no matter how much I scrubbed in the shower or how much of my normal body lotion I applied. Sorry if it’s TMI, but literally minutes after applying this for the first time on my arms, I was able to basically just wipe off that dead layer of my skin, revealing much softer and more supple skin underneath. This is an issue that has been plaguing me for over a year that was seemingly solved in one day. Additionally, I find that the scent is very pleasant. It weirdly reminds me of Froot Loops at first, but in the best way possible. It’s just got that nice citrus-forward, sweet fragrance, and as it dries down the scent gets mellower and more creamy as the lemon settles into the background. It’s definitely got a gourmand scent imo, but it’s not cloyingly sweet or artificial. It just genuinely smells like madeleines with lemon curd or something. I think the Shea butter is largely responsible for the creamy, vanilla-like scent that develops after a couple minutes. It’s very nice, I find myself smelling my hands for like an hour after I apply it because it’s just so delicious! It doesn’t have a strong throw at all once absorbed, the scent fades to only be detectable if someone is inches from your skin, so it hopefully shouldn’t annoy people around you unless they are severely intolerant to fragrance.

I would not recommend
Scent: Coconut, Size: 3.3 Ounce (Pack of 3)
First problem…the product description says “scent coconut” which is a false description. I would describe the scent as “medicinal” and of course reminds me of being in a hospital. Second problem…a reviewer called this item non greasy. This product is very greasy/oily and is slow to absorb. The good thing about this item is that its effective for dry skin. Having tried a couple dozen hand creams, my top 3 in ascending order are… 3. Okeffees working hands. Unscented . If you’re working outside, landscaping, etc, this is excellent. 2. Ahava. Strong masculine scent (musky). Works great. Not greasy or oily. Fast drying. The only negatives are: it’s not always in stock, it’s expensive. 1. Jack Black hand healer. Slight scent from eucalyptus (smells similar to menthol). Works great. Not greasy. Fast drying. It’s expensive however significantly less expensive than Ahava. It’s also much easier to find in stock.
