The Lowdown takes everything we learned developing our full suspension line, and directs it into a long travel bruiser. We still have a penchant for 4130 steel, 29" wheels, slack head tube angles (63.5°) and steeper seat tube angles (79°), but now we've paired all of that with 170mm up front and 158mm out back.

The way we see it, we're still drawing strongly on our hardtail roots and design philosophy, we just removed one more constraint.

NEW! Our Mullet link allows you to run a 27.5" rear wheel, while maintaining the same geometry, travel and kinematics. 27.5" rear wheel is sold separately.

Lowdown Sizing

Note: This is an approximate guide, some people have longer legs than others! Feel free to contact us to discuss.
If you're between sizes, it's a good idea to try to ride them both, either by hopping on a demo or stealing from a close friend.
If that isn't an option, examine reach, stack and ETT numbers on your current bike and compare.

Devil's in the details

We left no stone unturned when designing our new suspension fleet.

Whether its our injection-moulded chain stay protector to help keep the paint fresh and the noise low, or the accessory mount and ample room for a water bottle even on the size small.

We've thought about the small details, because every single person who works at Chromag, is a rider too.


As you might expect from any Chromag, The Lowdown relies firmly on a 4130 chromoly steel foundation. We believe that the ride characteristics and aesthetics for which our hardtails are known, absolutely translates to a full suspension platform.

However, a dual suspension rig provides different challenges, which is why we opted for 6066 aluminum chainstays and seatstays. Primarily for weight saving and stiffness, but the chainstay also houses bearings which is more difficult to do in steel. Using a mix of aluminum and steel helps strike the right balance of compliance and rigidity.

The rocker is made from forged aluminum due to its strength/weight ratio and ability to be machined.


Like all our products, the Lowdown was designed with durability and serviceability in mind. The main pivot uses an expanding collet axle system, designed to avoid over-preload and over-constraint of bearings. This results in a main pivot that spins smoother, for longer.

All pivots spin on Enduro MAX bearings that are well-sealed, long-lasting, and commonly available through most local bike shops or as kits on our website. The pivot hardware is machined from high-strength 7075 aluminum, and the custom-drawn tubing is made from the same 4130 chromoly steel you’ve come to know on our hardtails.

Frames are assembled with plenty of grease, and each one is checked over by one of our mechanics before leaving Chromag HQ. The Lowdown is a no-nonsense frame that is built to last.

Head Tube Badge

Your bike is special. The head tube badge is the finishing touch so we’ve always made a point of taking the time to do something interesting with it. Our head tube badges have changed over the years and are an indication of the time each bike was made. Whether it’s a cast bronze, or polished stainless steel, water cut aluminum or a 3D CNC carving, each one represents our commitment to detail.


The UDH is designed to optimize shift performance across all bikes as well as create a sensible solution for replacing damaged hangers. The UDH has been widely adopted throughout the cycling industry with hundreds of models already featuring it.

Suspension philosophy

We chose to use a 4-bar suspension layout for the Lowdown, with a main pivot located just above the bottom bracket, a seattube-mounted rocker link, and a vertically oriented, trunnion-mounted shock. We found this layout to strike a good balance of tuneability, ride quality, and elegant simplicity. A 4-bar layout offered enough tuning parameters for us to design the suspension characteristics the way we wanted them, simultaneously achieving our targets for leverage ratio, progression, anti-squat, and anti-rise.

At the same time, it keeps things simple and intuitive. With no hidden hardware, sliders, or concentric multi-link pivots, every pivot can be accessed, bolt-checked, and worked on without taking the whole bike apart.
