MPX HORST LINK SUSPENSION

MPX Horst Link design helps isolate braking and pedaling forces from FAULTLINE MPX’s suspension activity, which means reduced brake jack and improved traction under power.

KS VANTAGE

All FAULTLINE MPX models feature a KS Vantage dropper seat post, which offers up to 30mm of user-adjustable travel. To get the right fit dialed in it’s as easy as turning a 3mm Allen bolt at the top of the post.

V2 GEOMETRY

FAULTLINE MPX’s V2 geometry features a 77-degree seat tube angle which places riders in an optimal pedaling position for seated climbing.

TUBELESS TIRES

The benefits of a tubeless tire setup are undeniable: improved traction with lower pressures and a minimized risk for pinch flats. Vittoria Agarro tires featured on FAULTLINE MPX models make tubeless setup a breeze.

UDH

UDH (Universal Derailleur Hanger) design not only allows compatibility with modern SRAM drivetrains, but it also makes proprietary derailleur hangers a thing of the past.

PROGRESSIVE LEVERAGE

FAULTLINE MPX is designed with a moderately progressive leverage curve, which helps maintain support through the mid-stroke while offering a smooth ramp-up to full travel.

V2 GEOMETRY

A 66-degree head tube angle on FAULTLINE MPX strikes a nice balance by delivering composure on the downhills without the drawbacks of an overly-slack front end.

ISCG MOUNTS

Want to run a chain-retention device or bash guard on your FAULTLINE MPX? No problem, ISCG tabs are welded directly to the BB shell. 

MPX (Horst-Link) PLATFORM

There’s a reason Horst-link suspension platforms are popular. The combination of relative simplicity, effectiveness, and tunability is tough to beat. MPX is our take on the Horst-link layout, which gives FAULTLINE not only excellent pedaling efficiency, but also offers a supple, active feel while minimizing brake jack.

6061 ALUMINUM ALLOY

Metal rules. Especially the triple-butted 6061 aluminum alloy kind. Why? It’s lightweight, strong, and cost-effective (not to mention 100% recyclable), making it the perfect choice for FAULTLINE MPX frames.

Faultline® Close-Up Shock

PLAYFULLY CAPABLE

Short-travel bikes are making a comeback, and for good reason. Favorable suspension kinematics paired with proper geometry can make a 125mm-travel bike into one hell of a shred weapon. Our FAULTLINE MPX bikes feature a complete suspension platform overhaul, improved geometry, and three build options that each punch well above their price point. Look closely, you may have just found your next full-suspension bike.
