Tech / Geometry
On this page, you'll find information on how our frames are built, how they are designed and the details on the geometry for each model and size.
FRAME MATERIALS
REYNOLDS 725 TIG WELDED FRAMES
These Wabi frames feature traditional butted steel frame tubing using heat treated, Reynolds 725 chrome molybdenum steel. Each frame is hand tig welded, and all aspects of the alignment are checked before any frame leaves the factory. The fork features butted 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 an integrated brazed type.
REYNOLDS 725 LUGGED FRAMES
The Wabi lugged frames feature traditional butted steel frame tubing, using heat treated 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 frames are 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.
COLUMBUS SPIRIT SINGLE SPEED FRAMES
This frame features triple butted Columbus Spirit steel frame tubing. Each frame is hand tig welded and all aspects of the alignment are checked before any frame leaves the factory. The fork features carbon fiber blades, with an aluminum steerer.
FRAME DESIGN
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. We design the frames 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 and more difficult to control, especially at slower speeds. Richard, our founder, designed our bikes using traditional road racing geometry with tweaks for fixed gear riding.
Samples are built for stress testing on a machine. Wabi frames are built 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 Wabi 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. We believe your Wabi bike will amaze you, both with its beautiful workmanship and its plush ride.
FRAME GEOMETRY
IMPORTANT NOTE: Seat tube sizing is Center-to-Center (C-t-C). This is center of the bottom bracket shell to the center of where the seat tube meets the top tube. Other manufacturers may use Center-toTop (C-t-T). This is center of the bottom bracket shell to the top of the seat tube. This can mean the listed sizing can differ fro 2-4cm, but the frames may actually be the same size.
