(marketed as "Turn Helper Concept") and used Pivot’s hollow-core aluminum construction.
In the mountain biking world, few projects have achieved the legendary, meme-shattering status of Pinkbike's . What started as a satirical thought experiment on the future of mountain bike geometry turned into a two-part video series and comprehensive review cycle that fundamentally changed how riders look at bike design.
See how Pinkbike took the data from the first experiment and engineered a slightly more refined, yet still completely unhinged, second iteration of the bike. pinkbike grim donut unblocked
