Bikesales4u have just launched the Duell Roadmaster Audax frameset which is custom made in The Netherlands.

The frame is handbuilt using Dedacciai COM 12.5 tubing which was launched in the late 1990s with the name 18MCDV6 – the code for the steel alloy.

These tubes have a much higher tensile strength (1250 N/mm2) than commonly used chromoly steel tubes (up to 450 N/mm2). Plus, the hardening of the heat-treated tubes after the welding process makes the weld exceptionally strong and allows thinner tube walls to be extremely stiff. Miguel Indurain is among the famous cyclists to have used these frame tubes.

Later, Deda further increased the strength of the tubing with heat treatment (SAT 14.5 tubing) and a kinetic surface (EOM 16.5 tubing). These treatments produce the Dedacciai 12.5 tubing that’s used to build the Duell Roadmaster frame.

You can order a custom frame sized between 49 and 67cm. Frames can be specified with standard rear derailleur dropout, for use with a Rohloff Speedhub chain tensioner, or with a smooth dropout for using an eccentric bottom bracket.

A Roadmaster frameset including steel forks, headset and seat post clamp costs £1,399. An extra £100 gets you a full carbon fork instead. For all the details go to bikesales4u.com.
