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.

Groupset

Featuring ultra-reliable wireless shifting, innovative gearing, AXS App connectivity, and refined hydraulic disc brakes. It’s everything you could ask for in a modern groupset.
Wireless Shifting
Clean, safe, and reliable. SRAM Rival AXS wireless gear shifting is simple and intuitive. One button to go easier, one to go harder. Simple. A 60-minute battery charge lasts 60 hours, that potentially weeks and weeks of rides. It’s 100% waterproof and proven in the hardest racers on earth. No cables to stretch or get clogged with dirt. SRAM Rival AXS just works.
Efficient and Capable Gearing
Innovative 12-speed gearing provides huge range and tight jumps. Meaning you’ll always be able to find the right gear. Whether climbing the steepest hills or sprinting to the line. We’ve paired a 48/35 tooth front chainset to a 10-36 tooth rear cassette. For top end speed, this gives you a harder gear than a traditional compact groupset. And for the hills, the 35-tooth inner front chainring and 36-tooth cassette gives you the climbing potential other groupsets could only dream of.
AXS Mobile App
Control, personalisation, and monitoring are at your fingertips with the AXS mobile app. See how much time you spend in each cog, customise your shifting configuration, check battery charge status, and update firmware as needed right from your phone.
Disc Brakes for ultimate control
SRAM Rival AXS provides the best braking experience for all riders. Powerful hydraulic disc braking to inspire confidence, whatever the weather. No more achy hands after long descents. Reach adjustability for different hand sizes mean suitability for everyone.
