The Monk
4130
Almost all Chromag frames are made from quality 4130 chromoly steel tubing. Chromoly is an abbreviation for chromium-molybdenum indicating the materials that the steel is alloyed with.
The added chromium helps increase the steels hardenability and also provide some corrosion resistance.
The molybdenum helps to increase the toughness of the steel.
It has a high tensile strength but is also malleable which is what gives our frames their notorious ride quality and feel. Chromoly is often used when more strength is required than that of mild carbon steel.
It falls under the AISI (American Iron & Steel Institute) 41XX designations which is where the “41” comes from. The “30” indicates it contains approximately 0.30% carbon by weight.
Chromoly is much stronger than traditional 1020 steel and it has a higher 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 riders love to throw at it.
The monk has been a staple in our line-up for almost 2 decades.
key features
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.
We've never tried to hide the fact some of our products are made in Taiwan, in fact, we're proud of it.
Our Taiwanese partners are incredibly skilled and some of the best in the business.
As you would expect, these products are held to the same strict standards that we're renowned for.
The Monk comes with holes in the headtube ready to accept gyro tabs.
If you like to throw the bars so much you run out of brake line, then having a gyro is essential.
The Monk comes with Gyro tabs and screws packed with your owners manual.
Yes, steel might be a little heavier than it's
more flashy contemporaries, but these bikes are built to last. We use high grade 4130 Chromoly steel which is durable and contributes to a great feel as well. Steel tubes are known for their compliance and lend a calm, vibration-absorbent feeling to the ride of the frame.
Steel can theoretically last forever provided it's ridden within the scope for which it was intended.
Whether you get your bike in a box, or roll it out the front door here at Chromag HQ, you can rest assured your bike has been pored over with pride, and built with the utmost attention to detail by one of our extremely talented mechanics.
Threads are chased, seat tubes are reamed, head tubes are honed, fits are checked and checked again, all to make sure when you get your bike, everything is absolutely dialed.
Horizontal dropouts are a crucial part of a single sped setup, allowing you to tension your chain without the use of a derailleur.
Our built in chain tugs also allow you to dial in the chain tension, and keep it that way, even during mis-judged 360's and sideways landings.
The mountain biker’s dirt jumper.

At home on the pump track or your local spot the Monk has timeless style and character. The geometry is on the more familiar to mountain bikes end of the scale allowing you to get comfy quickly.

Sizing
The Monk has a very different fit to our other bikes. It only really gets longer (not taller) as you go up in size, which is why they are labelled short, long etc (rather than small, medium, large).

FAQ's
A 2.2” Maxxis fits with appropriate room around it.
No, there are no ISCG mounts on the Monk.
All our frames can work with +/-10mm of fork travel. To generalise the geometry change is around a 0.5° slacker head tube and seat tube angle for every 10mm added.
We setup our complete Monks with a 52mm chain line
With a 52mm chainline (SRAM boost standard), the Monk can fit up to a 34-tooth chainring.
For context, most of us here are running a 30t, with a 10/52 cassette.
There is a serial number on the back of your fork arch, adding this to Rockshox Trailhead app along with your weight gives a good baseline setting.
It does, however the specific blend of steel we use (CR-MO) has very good corrosion resistant properties. You can further protect things internally if you live in a partially harsh area or have concerns. Fluid Film is our recommended product for this.
Hope and other large 4 piston brake calipers can be tight, Sram codes fit just fine. Given the bikes intentions it is not expected that many will want to fit the largest heaviest brakes to it. Please let us know if you have tried to fit a more obscure component and faced issues.
Greasing you seat post prevents this issues, we strongly recommend re-greasing every 6 months at a minimum.
Not much! Here's what you need to do if we shipped your bike to you:
• Inflate tires to desired pressure. (Sealant is already installed)
• Install brake rotors, tightening bolts to 6.2Nm.
• Attach derailleur to frame, tightening to 9Nm making sure that the B-tension tab rests properly against the derailleur hanger stop.
• Grease headset bearings, install fork and handlebar, positioning the headset spacers above or below the stem according to rider fit.
• Align handlebar stem, preload headset and tighten stem pinch bolts to 8Nm.
• Install wheels, tighten axles.
• Install chain with quick link.
• Grease pedal threads and install pedals using pedal washers supplied.
• Adjust brakes, shifters, saddle position and height for personal preference.
• Set up suspension.
• Bed-in brakes. (Roll down a gentle gradient dragging one brake at a time. Avoid locking them up.)
• Go ride!
Note: If you had to Google "Nm", or you don't know which way to install your rotors, you should probably get a qualified mechanic to build your bike!
Here's what's been done:
• Chain length adjusted.
• Gears adjusted.
• Brakes set up and bled.
• Handlebar tightened to 6Nm.
• Grips tight on handlebar.
• Crankset tight, bottom bracket tight/adjusted.
• Saddle and seatpost tight.
• Seatpost greased *make sure to re-grease every 6 months!
• Tire sealant installed.
• Cassette tight.
