Frame

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.
Versatile Road Geometry
Lightweight and High Strength Aerospace Grade 9 3AL-2.5V Titanium
Capable 700c x 32mm Tyre Clearance
Premium CNC Machined Detailing
Lifetime Frame Warranty

Now featuring SERVO WAVE ACTION brake technology, the new DURA-ACE ST-R9270 brake lever delivers modulation and control like never before. Wireless shifting keeps your bike looking clean while offering the fastest, most precise gear changes available. All of this resides in a dual control lever to employs the most advanced materials to offer light weight and refined ergonomics that provide comfort and control for the most demanding conditions.
With an all-new mono-body construction design, high performance braking has reached a new peak. The BR-R9270 caliper drops weight while also providing increased pad clearance, ensuring a quieter ride. Lastly, a new bleeding process makes maintenance easier than ever.
The DURA-ACE FC-R9200 crank performs two vital functions; transferring your pedalling effort into the drivetrain and ensuring the fastest, most precise front shifting available. With HOLLOWTECH II crank arms to ensure light weight and Shimano's class-leading chainring designs, the FC-R9200 won't let you down.
