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.
all tubes of the Liteville are seamlessly drawn from 7005 aluminum.
All frame parts like bottom bracket, rocker arms or drop-outs are being manufactured on state-of-the-art CNC machines.
Only especially trained welders with long experience in aluminum welding work for Liteville. A custom welding filler is being used.
Already after tack-welding the frames are being checked for the first time and trued if needed. During the welding process truing is repeated up to 10 times. Only like this, our high standards in regards to precission can be achieved.
... it is a very important step, responsible in part for durability and stiffness of the frame. Test protocols ensure adherence to our specs.
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.
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.
Before anodizing, the surface is shot-peened with small steel balls to harden the surface. This improves hardness compared to glas-peening.
... are lasered into the anodized surface. The laser burns up the color pigments to show the natural color of the aluminum.
