Introducing the New LVN140 Chromoly Steel Mountain Bike Frame | USA Built – Full Suspension MTB Frame

Linkage Driven Performance

While a single pivot is enjoyable, introducing a link transforms it into something even more fun and competitive. Single pivot steel frames excel in agility, but when you add a link, the dynamics become even better. The addition of a link enhances resistance to bottoming out, facilitates easier shock tuning, and eliminates the complexities associated with multi-link maintenance.

Effortless Climbing

The LVN140 conquers technical hills with ease, offering ample travel to absorb drops, roots, and boulders. Our meticulously optimized Pivot Point ensures the bike delivers over 100% Anti-squat throughout its travel. This design ensures that when you pedal, the power is efficiently transferred to the ground, maximizing performance and minimizing energy wastage.

Durable and Confidence Inspiring

The LVN140 is our latest and greatest and is a culmination of all the things we have learned making steel full suspension frames. While steel is incredibly strong, when used in a bicycle frame the tubing wall thickness needs to be optimized for longevity and durability. We put in the work to ensure that the the the weight of this frame is low and centralized. What that means is when riding, is your frame is working with you providing confidence and stability thanks to optimized handling and performance characteristics.

Mid Pivot Balance

Our carefully calibrated mid-high pivot strikes the perfect balance on the trails. The regressive initial axle path counters a shrinking wheelbase during descents, providing stability. This balance prevents handling alterations and unpredictable characteristics during cornering, offering superior performance in various trail conditions.

CNC Machining Excellence

Elevating the frame’s feel, we incorporated CNC machined shock mount/pivot arms. The 4140 chromoly arms, despite being challenging to machine, exemplify the frame’s high-end quality. This commitment to precision machining ensures that our frame outperforms others in its class.

Single Pivot Steeze and Durability

Featuring a stainless steel pivot axle and double-stacked quad 6001-2rs bearings, our frame excels in longevity and rigidity where it matters most. The advantages of a single pivot design include easy maintenance, cost-effectiveness, predictable rides, and enhanced speed on steep descents.

Adaptable Design

Slider Dropouts provide fine-tuning of rear wheel adjustment to accommodate various tire sizes from different manufacturers. Our innovative approach ensures compatibility with your preferred wheel and tire sizes without compromising the qualities you desire in a chromoly steel frame.

Modern Specifications

Designed for a 73mm BSA bottom bracket, 148mm boost, internal cable routing for dropper seat posts, and tapered forks, the LVN140 incorporates all the modern mountain bike specifications in an exciting and high-performing steel frame package.

Geometry & Sizing

Name: LVN140 MTB Frame | 140MM Rear Travel | Chromoly Steel Full Suspension MTB Frame
SKU: LVN140_steel_mountain_bike_frame
Availability: InStock

Sizing Tip:

We recommend short stems 32mm-40mm in length for proper sizing and handling characteristics. Pay attention to the Top Tube and Reach measurements, they may be different from what you’re used to do to our seat tube offset to clear the rear tire at full travel.

The LVN140 was developed with progressive geometry in mind. Utilizing slack geometry with 37-46mm offset forks provides a stable, fast and well handling steed.

Why Chromoly?

Chromoly is much stronger than traditional steel and aluminum alloys. Chromoly is the most earth friendly material that we’ve seen besides bamboo that’s being made into bicycles. Studies show that chromoly requires 6-11 times less energy and emissions than competing materials to mine, manufacture and process.

Most people looking to buy our frame will have their minds made up on chromoly steel frames and prefer this material for their next frame but if you’re new to or curious about this amazing material, here are some of the advantages you’ll hear from experienced riders:

Quiet

Chromoly steel bike frames possess a natural flex that absorbs sounds. While not completely silent when contact is made with rocks or roost, the ride is very stately feeling. Focus on the path ahead, not nuisances.

Durability

You’re buying a bike that will stand the test of time with proper care and maintenance. Imagine owning a bike that can be welded and repaired rather than degrade and be thrown away. Most people consider the user-friendly nature of chromoly to be a very wise investment.

Feel

Our steel full suspension mountain bike frames are engineered with controlled flex, working with the natural characteristics of heat treated chromoly and stiffening it up where it’s necessary for maximum efficiency. Chromoly tubing for a mountain bike is very thin yet incredibly strong, it has an inherent flex that people strive for in order to reduce vibrations translated to their hands and feet which works to reduce rider fatigue and increase rider comfort. Ride longer, more comfortably and much harder. Slight flex in the rear keeps the wheel planted in sharp hard turns keeping you on two wheels.

Strong

Chromoly’s strength to weight ratio rivals that of titanium yet it’s more affordable. Rest easy knowing what you’ve accepted as norm, steel is strong. Imagine a high-tech, lighter weight yet stronger alloy of steel being made into a frame for your next mountain bike. There are pluses and minuses for every known material being made into a mountain bike frame but welded seems, not glued, is something we personal feel is more solid and secure. Metal melted to metal, not piece, glued to piece. Fancy marketing words will lead you to believe other materials are “one solid piece” (“Monocoque”) but research shows that’s misleading, it’s actually multiple segments glued together into one piece which is strong too for only a comparably very short lifespan. Ride safe though, we can’t be held responsible for your new found feel of steel, ride at your own risk, ride responsible.
