The Special features traditional butted steel frame tubing, using heat treated, oversized Reynolds 725 chrome molybdenum steel. Each frame is built by hand, using low temperature brass brazing and investment cast lugs and bottom bracket shell. The Special is produced to our specs in Taiwan, but by a company that has been producing pro level brazed steel frames for decades in Japan. The alignment of all aspects are checked before any frame leaves the factory. The fork features tapered cro-moly steel blades, brazed to an investment cast crown. Fork tips and rear drops are precision investment cast steel, and the seat post clamp is integrated into the seat lug.
There are two critical aspects of frame design- cockpit design (rider fit- where the rider connects to the bike and where these points are in relation to each other) and steering/handling. Our frame design is done here, in-house, to ensure the desired characteristics. The seat tube angle, top tube length and stem height and length are the key elements to consider for correct rider fit. Then, for handling, stability and agility are both considered- too stable and the steering is heavy; too quick and the bike is twitchy, more difficult to control, especially at slower speeds. We designed the Special using traditional road racing geometry with tweaks for fixed gear riding (for more info on our frame and wheel design philosophies, click here).
Samples are then built for stress testing on a machine. We build to the most rigid standard, the EN, the current European standard. This is your assurance of the quality and structural integrity of each Wabi Cycles frame.
The Special, as the name implies, is not just another steel frame- the quality of tubing, design and manufacturing combine to create the traditional ride that the best steel frames are known for. The Wabi Special is unlike any other fixed gear frame you will see- it's the perfect combination of function and art.

A word on fit. There is no one way to nail correct fit on the first try. If you've been riding a long time, you probably know what you need, from the dimensions on an existing bike (see our fit guide page for more info).
One word of caution about positioning adjustments- general wisdom is to not radically change seat height, to avoid knee problems. This is more important the more you ride. So, try to get as close to right as you can initially on seat height and then modify by 3 or 4mm as needed.
I've had many years of experience in fitting people to bicycles, both in person and long distance, so if you have any questions as to what frame size you should get, or other dimensional questions, contact me and I'll be glad to help you.
Steel is steel is steel, right? No. The type of tubing matters. Click here to connect to an article on steel tubing. It can be confusing- hopefully this article will help fill in some gaps.
*Traditional steel frames use 25.4mm diameter TT, 28.6mm ST and DT. Oversized uses 28.6 TT and 31.75 DT. ST remains the same.
