Clean lines, rounded tubes, uncluttered and unphased, The Holdsworth Helm has been meticulously designed and constructed using Aerospace Grade 9 3AL-2.5V Titanium, for unparalleled lightness and strength. With geometry that retains the high-speed pedigree of a pure road bike, but with modern touches that make it perfect for ultra-endurance expeditions also. This is a bike made for long, fast days in the saddle.
A CNC detailed tapered head tube allows for a large weld platform and bigger bearings. Resulting in a stronger, less flexible, and better handling front end. Hourglass profile chain stays and a 27.2mm seat post give comfort and spring. The bridgeless seat tubes offer sprightliness, whilst offering a clean aesthetic. Power is transferred directly though the creak free BSA threaded bottom bracket, which has been CNC engraved with the coordinates of the radar station at the peak of Great Dun Fell.
