Overview

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.

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

Dropper Ready

Dropper Ready

Built to accept an internally-routed 27.2mm dropper seatpost, which shouldn´t be a surprise on a bike this capable.

Proportional Response

Proportional Response

Tuned for the rider, our size-specific construction creates optimal stiffness and compliance for each frame size. So, every rider benefits from the ideal ride feel and comfort of KingPin.

OutFront Steering Geometry

OutFront Steering Geometry

Confident stability meets nimble agility. An extra long fork offset paired with a slack head angle keeps the steering light and lively, yet delivers unreal confidence at speed and in the rough stuff.

Tidy does it

Tidy does it

Internal cable routing throughout the frame, combined with Conceal Stem, delivers a tidy, integrated look.

KingPin

KingPin

Our innovative gravel rear suspension is light, simple, and effective. A thru-axle pivot in the seat tube allows the rear triangle and seatpost of the bike to flex vertically, delivering up to 30mm of bump-smoothing travel.

StashPort + StashBag

StashPort is our take on a downtube storage system, accessed beneath the water bottle cage. Every bike includes StashBag, a specially designed bag for your essentials.
