Our take on the ultimate all-round gravel bike. Go anywhere, bring everything and then keep on going.
One chainring, endless possibilities. The Topstone 3 GRX - 1X delivers simplicity without sacrificing performance. A Shimano GRX610/820 blended group keeps shifting precise and reliable, while KingPin suspension takes the sting out of rough terrain. WTB tires keep you connected to the trail, making every ride a good one—whether it’s a quick lap or a full-day escapade.
FEATURES:
- Smiles for Miles: Kingpin is our lightweight, go-for-longer rear suspension. Maintenance-free and complexity-free, it gives the Topstone frame legit rear-wheel travel without compromising stiffness for the sprint. Kingpin provides a smoother ride, more traction to push harder, and more give to take on the rough stuff. You’ll hardly know it’s there, but you’ll be very glad you’ve got it.
- Bring It All: Our all-new StashPort storage system in the downtube is designed to be concealed yet convenient. Paired with the special StashBag, you can bring your essentials along for the ride and know that they’ll be kept safe, whatever you get up to out there. Meanwhile, multiple mounting points on the frame, mean more gear and more adventures.
- Tuned Ride: A dialed-in ride, just for you. AKA: Proportional Response Construction. Everything from the carbon layup to the geometry on Topstone is individually tuned by frame size. So that the bike – including KingPin suspension – works in harmony to give you the best ride for you and your dimensions.

Best money ever spent!
Color: Brown, Size: 6 Panels
I LOVE this divider! I live in an apartment with a covered patio that faces the parking lot and desperately needed some privacy. I was hesitant about ordering this due to mixed reviews but I'm so glad I took a chance. I bought the six panel in brown and it came in perfect condition, covers the entire opening, it's lightweight but sturdy enough for wind. In the 5-6 months I've had it outside it only blew over once in a hurricane and that was my fault. I should have taken it down, I knew the storm was coming...but no damage was done! It looks amazing and now I can go out on my patio day or night with complete privacy. If you're on the fence as I was, get it! Great product!

Buyer beware!
Color: Off White, Size: 6 Panels
Beware not at all a good quality. Screen is made of a very fragile product. Very cheap looking not at all anything I would want in my home. And once you have purchased it basically it is yours because Amazon can't help you because it is a third party seller. Which means you have to work with the seller directly and they want you to send it back to them on your dime to California which would almost cost the same as the purchase price.
