What if mayhem unveils elegance?
Let turmoil reveal
the polished experience of Rapha
Turmoil
=
Unaccustomed Transition
In non-traversable sections, riders dismount, carrying their bikes until a rideable path emerges,
then remount to conquer the road again. Pedaling efficiency is a direct trade-off for foot mobility.
THE POLISHED EXPERIENCE
The freedom to explore unimpeded by obstacles
Core Concept
Flowing Feedback - Constant adjustments overtime.
From dismounting and trekking with the bike (turmoil), and then readjusting for optimal riding, ensuring a polished experience unimpeded by obstacles.
Pressurized piezoelectric pad generates electricity.
“Piezoelectric materials produce an electric voltage when they are placed under stress. This may be a result of bending, stretching, or a variety of other means including when they are subjected to vibrations.”

Electricity stimulates 4D printed material
“When exposed to a stimulus such as heat, moisture, light, or electric current, structures undergo a change in material properties or shape over a length of time. These characteristics may be tuned and “programed” into the specimen.”

Rearward shift of the pedal joint for improved MTP mobility
“Placing the cleat slightly behind the ball of the foot often decreases compression of nerves and blood vessels under the metatarsal heads, minimizing the chances of foot and toe numbness. Anecdotally, many clients report this feels more powerful and stable.”
