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.

Campagnolo Chorus disc brake 12-speed groupset.
The Campagnolo product that combines racing performance with the needs of endurance. Designed for unforgettable outings where the entire day is spent in the saddle, the specific combinations of the Chorus 2x12 make it a versatile, simple and high performance groupset, however it's used: from Granfondo rides to adventurous Sunday spins to quick blasts on the bike after work.
As per tradition, the use of different materials and consequent little additional weight, together with a rear derailleur redesigned to house larger cassettes are the main elements that make this new Chorus 12-speed stand out from the crowd
Smooth, responsive shifting.
The Chorus derailleur benefits from the same technology and design of the top end Campagnolo components, incorporating the sophistication and performance of the 12 speed Record and Super Record. Mechanically the same as the more expensive groupsets, with our choice of an 11-32 cassette mated to a 52/36 chainset, delivers precise, smooth and responsive shifting at the expense of only a few grams.
Powerful hydraulic brakes.
The flat-mount Campagnolo brake calipers ensure powerful, modular braking in any situation owing to pistons measuring 22 millimetres in diameter. The pad return is now optimised to ensure that there is no friction when the brake lever is released. A special metal plate positioned between the pad and the caliper piston, cushions the vibrations during braking.
