NV170 Steel Mountain Bike Frame

From our years of experience with many other bikes, finding what we loved and disliked, they always left us with a bigger dislike list than love list. They did a satisfactory job but we wanted a bike that blew all the others away. This was the motivation for the NV chromoly steel full suspension frame, the best of what we loved with the added bonus of our features that we wished we had such as a comfortable yet supportive ride.

High Travel Meets High Pedal Efficiency

We all know 170mm of travel gives riders plenty of squish for shredding down most any trail but what happens when the lift or the shuttles aren’t running? Our NV170 Chromoly Steel Full Suspension Dream Build Kit is like a downhill bike that pedals up really well. NV170’s pivot point has been revised to offer over 100% anti-squat for more pedaling efficiency than ever before! Our 2022 NV170 Chromoly Steel Full Suspension Mountain Bike Dream Build checks all the right boxes. We’re able to keep up with the trends faster than the big brands and give you a bike that won’t become obsolete next year. We always stay ahead of the curve on Geo.

CNC Machining

We opted for CNC machined shock mount/pivot arms to help give our frame it’s high end feel. Nothing says “high-end” more than CNC machined parts, especially our 4140 chromoly arms which are not kind to tooling and extremely expensive to machine. We spared no expense to offer a frame that despite it’s simplicity, it’s overachieving compared to bikes that cost a lot more.

Single Pivot Steeze and Durability

Stainless steel pivot axle and quad 6001-2rs bearings double stacked for longevity and rigidity where it matters most. Thanks to modern suspension technology, single pivot is back. Why single pivot? Easy maintenance and easy on your wallet. The ride is predictable and it doesn’t get hung up as easily on impacts which allows you to carry more speed on those steep descents.


Slider Dropouts enable fine tuning of rear wheel adjustment due to wildly variable tire manufacturer sizing measurements. We think outside the box, so we offer a solution to fitment of your favorite size wheels and tires without sacrificing anything you’d love in a chromoly steel frame.

Modern Standards

Made for 73mm BSA bottom bracket, 148mm boost, internal cable routing for dropper seat posts, tapered forks. All your modern trail bike specs in a more progressive and exciting package.

Why Chromoly?

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:


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.


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.


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.


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.

  1. Marcus Melhuish (verified owner)

    I’ll start by saying steel is real! I have always been on a steel hardtail until I ordered this frame and it is amazing! currently running a 170mm bomber up front with 29” wheel and 27.5 out back and this thing handles like a trail bike and smashes rough terrain like a DH bike! The build quality is exceptional and looks sick too. All in all i could not be happier.

  2. Joshua Padilla (verified owner)

    Riding the NV170 through rugged terrain feels like riding on a well maintained singletrack. I run 27.5 Enduro/DH wheels with a 190mm RockShox Zeb fork and an MRP progressive coil shock. I frequently ride mine over obstacles such as large downed trees and root riddled drops and have yet to break anything after a few months of constant riding. I’ve damaged linkage bearings on my Trek and Haro full suspensions in the past and even even cracked aluminum frames before so the extra durable single pivot and rugged steel of the NV170 is very much welcome. Don’t let the externally routed cables put you off either, this only makes it easier to maintain/replace drivetrain and brake components (functionality vs cosmetic). I suggest the NV170 to anyone that wants an extremely reliable and easy to maintain platform for shredding rough trails!

  3. Jose (verified owner)

    Best enduro bike I’ve ever owned. Planted, silent and comfortable. It inspires confidence! I’ve beaten all of my previous times in the California Enduro Series with this bike!
