Smiles per Mile
Kingpin is our lightest and strongest rear suspension. Simple and maintenance-free, it gives the Topstone frame real rear wheel travel without compromising responsiveness, even during the most aggressive starts. Kingpin provides comfort and traction so you can ride harder, knowing you're protected on the roughest terrain. Discreet in appearance, but real in results and benefits.
Carry your gear
Our new StashPort storage system in the downtube is designed to be discreet while fully functional. Paired with the special StashBag, you can carry your essentials knowing they’re protected no matter what. Meanwhile, multiple mounting points on the frame allow you to attach more accessories and enjoy new adventures.
Ideal performance
Trail response tailored to you, thanks to our Proportional Response concept. Everything on the Topstone — from carbon lay-up to geometry — is individually adjusted for each frame size. This ensures that the bike’s response — including KingPin suspension — works in harmony with your weight and build, delivering the best experience on the trails.
*KINGPIN*
Our innovative rear suspension for gravel is light, simple, and effective. A thru-axle pivot in the seat tube allows the rear triangle and seatpost to flex vertically, providing up to 30mm of travel to smooth out bumps.
*STASHPORT + STASHBAG*
StashPort is our version of a downtube storage system, accessed beneath the bottle cage. Every bike includes a StashBag, a specially designed bag to carry your essentials.
*TIRE CLEARANCE*
The Topstone Carbon accommodates tires up to 52 mm wide in the frame and 56 mm in the rigid fork. On the Lefty Oliver, tire clearance is optimized for 700x47 mm, with height being the main limiting factor.
*DROPPER POST COMPATIBLE*
The frame supports a 27.2 mm diameter dropper post with internal cable routing — no surprise on a bike this capable.
*PROPORTIONAL RESPONSE*
Tuned for the rider, our size-specific construction creates optimal stiffness and compliance for each frame size. Every rider benefits from ideal ride feel and KingPin comfort.
*OUTFRONT STEERING GEOMETRY*
Internal cable routing throughout the frame, combined with the Conceal stem, allows cables to be routed cleanly inside with outstanding aesthetics.
