Donhou Bicycles launches new 3D printed steel cross bike
East London based Donhou Bicycles produces some lovely steel frames and has now brought steel into the modern era by using 3D printing
Donhou Bicycles last week launched the new DSS3 CX/Gravel steel frameset that 'pushes the evelope on custom steel'.
What brings this bike into the modern era is the inclusion of a 3D printed seat lug, which has been years in development, according to Donhou.
>>> Cross bikes for the 2017/18 season
This unique feature brings a whole host of benefits to the new steel DSS3CX / Gravel bike and allows Donhou to incorporate key cross style features into the steel frame.
The top tube has been ovalized for a more comfortable shouldering position. Seat stays have been set wider apart to better tyre clearance and means that cabling for the rear mech can be fully internal.
The tubing used is a mix of Reynolds and Columbus steel and is built to use thru-axels and flat mount discs.
In terms of builds, Donhou has two 'tunes' which is either CX or Gravel (see below) and offers a number of upgrade kits or a full custom build. It also offers three stock sizes in each tune and of course custom builds if nothing suits in those ranges.
