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.

Love these pants
Color: Apricot, Size: Large
These wide leg palazzo pants are super nice! The material is very lightweight, making them perfect for summer. They’re incredibly flattering, comfortable, and I absolutely love the fit. The drawstring waist and pockets are a great bonus!
For reference, I’m 5’10”, 170 lbs, and ordered a Large — they fit perfectly. Highly recommend if you’re looking for stylish, flowy, comfortable summer pants!

Love! New favorite pants!!
Color: Apricot, Size: Medium
I really love these pants!
They’re extremely versatile. I wear them to work in professional attire, then come home, throw on a t-shirt, and wear them to lounge for the evening. They’ll even be great over a swimsuit on vacation.
Bonus points for having pockets! They have been durable enough for my phone and keys without them dragging the pants down.
When I first received them, I was surprised by how thin and somewhat see-through the apricot pants are— to the point that I considered returning them. I’m so glad I didn’t! They are insanely comfortable. Don’t let the reviews about being see-through deter you. Work around it! One day of wear and you’ll see why.
I prefer to wear these with shirts that tuck in the front and cover most of my bottom in the back due to how see-through they are in this light color. The comfort is worth it!
They are long for someone my height, 5’2”. I wear them with a Sofft sandal that has a thicker sole that adds a little height. This prevents them from touching the ground without me having to pull up on them all day. I can easily and comfortably wear them a little high on the waist to help with the length, as long as I’m wearing the thicker-soled sandal (or a heel). I don’t wear heels, so it’s thicker soled shoes for me!
I don’t feel these are going to be the most durable pants and expect to replace them more quickly than other pants- but I do expect to get at least a couple of good years out of them.
They are lightweight and cool, perfect for summer and spring. I don’t see myself wearing them to work or anywhere outside during cold winter weather.
I read the reviews and ordered a size down. I’m normally a large, size 8-10, and the medium fits wonderfully and is very giving. If I liked a tight pant, I probably could’ve gone with a small.
I will absolutely be purchasing them in other colors!
With this apricot color you’ll need to wear white or skin-colored seamless underwear.
I took one star off for being somewhat see-through. Outside of that, they are easily 5 star pants. ⭐️⭐️⭐️⭐️⭐️
For the $20-$25 price, get them and thank me later!!

Great quality for the price!
Color: Apricot, Size: Small
Great palazzo pants! I was looking for something to wear in Florida to a graduation but did not want to be too hot. These pants are versatile and very flattering. So comfortable as well and no wrinkles! The length was perfect for me at 5'2" and they wash very well. I purchased slip shorts to wear underneath to avoid the dreaded panty line / crease, etc. and the slip shorts smooth everything out & make you look seamless!

So great, that I own 4 pairs of these Sampeel pants!
Color: Pattern Leopard, Size: Large, Color: Pattern Leopard, Size: Large
I own 4 pairs of these pants because I love them so much! I receive many compliments when I wear them. They are stylish, comfortable, and a great thin material that keeps you cool while looking professional. I am 5" tall and can wear them with heels without needing them to be hemmed (which is unusual for me when ordering pants). They have an elastic waist band with drawstrings so I can wear them while losing weight, they don't wrinkle easily, and they have pockets! Great pants for a great price! I will continue to purchase more throughout the summer.

The good with the bad
Color: Pattern Kah, Size: XX-Large
Photos in listing depict a LINEN pant - in the close up's you can clearly see a linen/cotton like material. To my surprise, these pants are a silky, polyester material. There is NO stretch - I am glad I purchased a size larger than what I consider my " roomy " size. These style is also depicted as a beige and black color pattern, they are more of a light mauve color out of the packaging. Took a steamer to them to get the wrinkles out. Suitable for tall girls ( I am 5'9 ) and wearing them with 3 in wedge. They are cute - dressy enough for a business casual office setting or a date night. Probably not the best for hot humid weather as they are not breathable.
