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. SRAM Force AXS offers the key features of RED AXS, in a more affordable package.
Wireless Shifting
Clean, efficient, and reliable. SRAM Force AXS wireless gear shifting is accurate and intuitive. A 60-minute battery charge gives up to 60 hours of ride time, it’s 100% waterproof and pro proven, from the World Tour to elite endurance races. No cables to stretch or get clogged with dirt.
Efficient and Capable Gearing
Innovative 12-speed gearing provides huge range but keeps jumps tight. Meaning you’ll always be able to find the right gear. Whether spinning up the steepest gradients or sprinting to the finish line. Reducing the size of the front chainrings allow for a more tightly packed rear cassette. We’ve paired the 46/33 tooth carbon chainset to the XG-1270 10-33 tooth rear cassette. For top end speed, this gives you a harder gear than a traditional 50 tooth compact chainset and 11 tooth cassettes. For when the road kicks up, the 33-tooth inner front chainring and 33-tooth cassette gives gradient conquering one to one gearing. SRAM’s proprietary Flattop chain is silent and ensures no watts are lost.
AXS Mobile App
Control, personalisation, and monitoring are at your fingertips with the AXS mobile app. See how much time you spend in each gear, customise your shifting configuration, check battery charge status, and update firmware as needed right from your phone.
Disc Brakes for ultimate control
SRAM Force AXS provides a pinpoint accurate braking experience for all riders. Powerful hydraulic disc braking performs effortlessly, whatever the weather. Carbon bladed levers are ergonomic and lightweight. Reach adjustability for different hand sizes mean suitability for everyone.
