The Classic features traditional butted steel frame tubing, using
heat treated, oversized* 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.

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. I
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, more difficult to control, especially at slower
speeds. I designed the
Classic using traditional road racing
geometry with tweaks for  fixed gear riding (for more info on
Wabi's
frame and wheel design philosophies, click here).

Samples are then 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
Classic 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. I
believe the Wabi
Classic will amaze you, both with its beautiful
workmanship and plush ride.

Steel is steel is steel, right? No. The type of tubing matters. Click

hopefully this article will help fill in some gaps.

Dimensions in mm            
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.
Reynolds 725 Heat Treated Chrome-moly Steel

Using an industry standard alloy with mechanical properties similar
to their famous 753 brand, Reynolds mandrel butt and heat-treat
this alloy so that thinner walls can be used compared to
non-heat-treated steels. 725 can be TIG welded and used within our
"Designer Select" combinations including 853 and 631 tubes.

Based on a 0.3% carbon steel alloy which has been heat-treated and
back-tempered for increased ductility. The chromium content
promotes hardenability and resistance to oxidation. The
molybdenum works in conjunction with the chrome to stabilize the
alloy and maintain strength after heat-treatment and in use.
Note that 42cm version uses 650C
wheels
*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.
