Efficient & Playful
Play in the parking lot and then get serious on the single track, this is your next frame. Our 2021 LV145 Chromoly Steel Enduro Mountain Bike Frame has grown up for 2021. We’re able to keep up with the trends faster than the juggernauts and give you a bike that won’t become obsolete next year. We’re ahead of the curve on Geo. Our LV145 MTB frame was designed for the rider that was looking for the best all-rounder they could find. Designed with a Mid-High pivot effect, this is a bike that pedals up better than the previous model. We also tune your shock for maximum pedal efficiency while enjoying the ride.

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

Slider Dropouts enable fine tuning of rear wheel adjustment due to wildly variable tire manufacturer sizing measurements. We thought ahead and found a solution to fitment of your favorite size wheels and tires without sacrificing anything you’d love in a chromoly steel frame.

Chromoly Steel
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 LV145 chromoly steel full suspension frame, the best of what we loved with the added bonus of our features that we wished we had.

Why Chromoly? Chromoly is much stronger than traditional steel and aluminum alloys. Heat treated Chromoly like what we use in our mountain bike frames is even stronger than commercial/common grade titanium with a slight weight penalty. Chromoly has a high strength to weight ratio and high tensile strength, which means we can use less material and achieve a product that can withstand the abuse that MTB endures without breaking easily. Ride safe though, we can’t be held responsible for your new found feel of steel, ride at your own risk, ride responsible. There are several factors to consider when it comes to mountain bike frame design. Some of the most important factors are weight, strength and cost. Our heat treated chromoly tubing is a material that offers high strength without an excessive weight or price tag.

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 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. Our LV145 steel full suspension mountain bike frame is engineered with controlled flex, working with the natural flex of heat treated chromoly and stiffening it up where it’s necessary for maximum efficiency.
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 safe 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, its multiple segments glued together into one piece which is strong too for only a comparable very short lifespan.
Chromoly steel mountain bike frames possess a natural flex that absorbs sounds. While not completely silent when contact is made with rocks or other roost, the ride is very stately feeling. Focus on the path ahead, not nuisances.
