Road - Complete Bikes and Framesets

Light, stiff, fast. The ride of steel. Why try to imitate it? Big Forest Frameworks frames are built to fit your body, riding style, and preferences for stiffness and comfort that you can't get in an off the shelf frame. Not to mention they are beautiful. We spent hundreds of hours in the workshop, riding through the countryside, and up mountain passes, to perfect what we think is the perfect road machine. But we also know that all riders are different. Our perfect bike is not your perfect bike, and it is the collaboration between the two of us that will make every ride on your Big Forest Frameworks Racer, feel like the first.

Options (Standard & Upgrade)


Columbus & Reynolds Tubesets

You'll find only the best steel in our frames, produced by Columbus in Italy, or Reynolds in the UK. We individually select each tube based on rider size, weight, and riding preferences for frame stiffness and comfort. Steel is famous for its ride quality, but it nevertheless takes experience, data, your input to build a frame that will ride the way you've been dreaming about. We bring that to the table at Big Forest Frameworks.


Bike Fit Session - Fine Tune Your Ride

Stop by the workshop for a bike fitting session in my Potsdamer workshop. We can fine tune your riding position before the frame is built so the fit is how you want it to be. Optimize your riding position for going fast, long days in the saddle, or the sweet spot in-between, a custom fit goes hand in hand with your custom built frame from Big Forest Frameworks. Can't make it to Potsdam? It works over e-mail as well. Fill out our order form, measure you body and current bike, and tell us how you like to ride.


Fillet Brazed Frames

Why a fillet brazed frame? Beautiful, strong, long lasting. The seamless transitions between the tubes on these frames make them look as if they were created from a single piece of steel. They are simple and elegant. Perhaps even ordinary from a distance. But when one gets a bit nearer for a closer inspection, the fit, finish, and function of a fillet brazed frame from Big Forest Frameworks really shines through. But fillet brazed frames don't only look good, they add to the lifetime of your frame significantly. The seamless fillets reduce stresses on the tubes, which increases the lifetime of the frame by 50% compared to a welded frame. Simply the highest quality one can come to expect.


Flat Mount Disc Dropouts

In 2015 Shimano introduced the flat mount disc mount for disc brakes on road bikes. We think it looks great and is here to stay, especially since Shimano has a long history of production some the the best disc brakes for MTB applications. For our 2016 Road and CX frames we are offering the option of a flat mount brake mount. These dropouts are available in either 10mm QR or 12mm thru-axle.


Low Mount Disc Dropout

The low mount disc dropout is our preferred dropout for frames configured for disc brakes. Placing the disc brake here helps to keep the bike looking clean and looks great.


Paragon Round Dropout

The Paragon Round Dropout is our standard dropout for frames with rim Brakes. It comes in either a QR or 12mm version. It is stainless steel and has a replaceable hanger. It saves weight compared the low mount disc dropout, and can be combined with a post mount disc mount if you prefer your frame to be configured for a 12mm through axle.


ISP (Integrated Seat Post)

Our ISP option really cleans up the look of the bike. It includes a Ritchey mast topper coated to match the color of your frame. It also saves a few games compared to a traditional seat post. Another feature of the ISP is that the brake cable can exit on the rear of the seat tube, which looks great and reduces cable rub!


Stainless Seat Post Clamp Adapter

Stainless steel adaptor for the seat post clamp - very sexy! Protects the frames finish from getting damaged over the years, and for this reason we recommend this option for all frames. It also increases the diameter of the the seat post tube to either 31.7mm or 34.9mm, the two main standards in use today, giving you the widest possible choice of clamps.


The Big Forest Frameworks Head Badge

A work of art in itself... the Big Forest Frameworks head badge. A beautiful thing designed by Daniel von weltunit, a design company based in Berlin, Germany. We are all about getting out on handmade bikes crafted with pride, and this badge fits perfectly. No shortcuts. No compromises.


Internal Brake Cable Guide (upgrade)

Internal cable guides for the shifter(s) and/or rear brake. Pick your bike up without grabbing the brake cable and scratching that nice paint job. A no brainer option you have to have and will thank yourself every time you put your hands around the top tube. And, these internal guides don't just put your cables on the inside, they also are beautifully sculpted on the outside, matching the seamless look of the rest of your fillet brazed frame.


Head Tube Mounted Gear Adjusters

I hate cables rubbing away at the paint on my bikes. This feature goes a long ways towards reducing that problem. Down tube mounted adjusters normally have the problem that the cable housing lies against the head tube. Every bump you ride over, the cable rubs away a little bit more of the paint. With this option there is no contact between the cables and the frame, so you don't even need to worry about applying plastic protectors.


Stainless Steel Front Derailleur Adaptor

Like the seat clamp adaptor, very sexy, and protects the finish of the frame from being damaged by a derailleur clamp.


Stainless Cable Guide & Adjusters

Over many years and tens of thousands of kilometers, we want your frame to not only still be riding like it did the first time you through your leg over the top tube, we want it to look great, too. All cable guides, stops, and bottle bosses are made of stainless steel. We also take the time to remove the finish from contact surfaces with water bottle bosses, brake mounts, and dropouts, so that when you tighten things down, it will look just as good when you loosen them up.


Custom Serial Numbers, Name Plates, Life Modus

It's a small detail, but that's what Big Forest Frameworks is all about. It is the little things that make what we do great. Choose you own serial number. Stamped in bronze and brazed to the frame. Letters and numbers are filled to match the frame color. Your birthday? Wedding day? Kid's birthday? Or get creative on that shit and tell the world what you want to say. Up to 8 numbers or letters on the inside of the chain stay.


Premium Frame Coatings

Our frames are powder coated by one of the best suppliers in the industry. This costs a bit more than is typical, but it is an investment in the longevity and good looks of your frame. The quality is so good that it takes a trained painter to tell the difference between our coated frames and a frame coated with wet paint. The advantage is durability, powder coasted frames are much more resistant to scratching and chipping compared to painted frames, important for bikes seeing mostly off road use. The Big Forest Frameworks logo on the downtube (and and any other graphics) are not just stickers. They are nestled under a protective layer of clear powder coating, keeping them from getting scratched when you ditch your bike going too fast into that sharp turn on your favorite trail through the woods. Choose from our standard colors, or upgrade to your favorite RAL color.


Internal Frame Protection?

Worried about rust? You don't need to unless your lock your bike from Big Forest Frameworks outside every night in the rain. We know you won't. The modern steel from Reynolds and Columbus is very rust resistant. Generally you can expect to be able to pass your frame from Big Forest Frameworks down to your oldest son or daughter if it happens to fit them. If it helps you to sleep at night, we would be happy to coat the inside of your frame with a protectant at the expense of a few grams.


Reynolds 931 Stainless (Upgrade)

For the ultimate steel ride, upgrade to Reynolds 953/931 and you'll never stop smiling each time you throw your leg over the top tube. While we don't think you need to worry about rust in or on any of your bikes from Big Forest Frameworks, frames built of Reynolds stainless steel simply will not rust. Enough said!


Carbon & Steel Forks (upgrade)

For the Racer we recommend a carbon fork (ENVE, 3T). Carbon forks can be optionally painted to match the frame or in a complimentary color.
