A personal touch on Ragot's bike is this moto inspired headset steerer damper. In heavy cornering, it stiffens up the steering feel of the bike. Zero offset stem for the Summum.
Hopey has been making those for over a decade now.
I'm surprised more people don't run them, especially on courses like Val di Sol, where there were slappers left and right in those rocks.
stiffens up the steering for cornering, also it wont allow hitting things like roots or rocks to quickly jar your steering, which could cause you to crash. it also would reduce arm pump, cause you wouldnt have to work as hard to keep your handlebars straight on a rough course.
