The Liteville tube set
To convert a frame design into reality there is no way around a
special tube set. The standard tube sets on the market do not give
the designer sufficient choice in connection points or the tubing
is underdimensioned in the critical areas, so in the end the design
would always be a compromise.
That's why all tubes for our Liteville frames are custom-made. Every single tube has been designed for the position it is used in and butted several times (5 times for the top tube). Seat and chain tubes even have different wall thinkness left and right to be correct for chain torque and brake forces. All these measures guarantee a frame stiff and light at the same time - with the strength to take what you'll ride with the bike.

Frame material
All tubes of the Liteville are seamlessly drawn from 7005 aluminum.
The CNC-Parts
All frame parts like bottom bracket, rocker arms or drop-outs are
being manufactured on state-of-the-art CNC machines.
Welding
Only especially trained welders with long experience in aluminum
welding work for Liteville. A custom welding filler is being used.
Heat treatment
... it is a very important step, responsible in part for durability
and stiffness of the frame. Test protocols ensure adherence to our
specs.
The bearings
Used in a Liteville frame are only high-quality, double-sealed
stainless ball bearings. All bearings are specific to their
position. Those bearings are more expensive but they guarantee long
durability and stiffness without additional maintenance.
Bearing construction
To keep the bearings in place we only use heavy-duty, fine-pitch
hollow Titanium bolts. The main pivot is designed to not exert
bending force onto the bolts. Into the inner rings of the main
bearings aluminum inserts are pressed, sitting themselves in
recesses in the bottom bracket. This guarantees the holding bolts
only being exposed to tensile forces only.
The surface
Before anodizing, the surface is shot-peened with small steel balls
to harden the surface. This improves hardness compared to
glas-peening.
Logos
... are lasered into the anodized surface. The laser burns up the
color pigments to show the natural color of the aluminum.
