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.

Great quality bamboo cutting boards
Size: Large-3SET
These cutting boards are very well made and feel solid. The bamboo is smooth, nicely finished, and already pre-oiled, which is a big plus. I like having three different sizes — it makes food prep much easier depending on what I’m cutting.
They look good on the counter, don’t slide around much during use, and clean easily with a quick wash. For the price, the quality is excellent. I would definitely recommend these if you’re looking for durable, eco-friendly cutting boards for everyday kitchen use.

Talk about high quality! I couldn’t believe the price of these THREE boards. They are so perfect for meats, veggies, fruits, charcuterie, really any of your needs. Major bonus is that they look amazing in your kitchen too! I love how easy they are the use, store and clean. Highly recommend!!

10/10 Would Buy Again
Size: Large-3SET
Absolutely gorgeous cutting boards. Bamboo is a rich deep drown, sturdy with all sorts of foods - vegetables, meats, fruit etc. Nothing sticks and very easy to hand wash - makes food prep a breeze. Great value, size as described, easy storage upright for drying.

Great quality for price
Size: Large-3SET
A little on the thin side, but it’s made with sustainable bamboo, and is nice to work with. Just don’t ever ever let a bamboo board like this stay wet for a long time. It WILL absolutely warp/de-laminate.
