From the A Return Tops website:
"The Donut aka Dilla is a hand made fixed axle return top manufactured by world famous creator guy Jensen Kimmitt. The name Dilla is a tribute to the late record producer and artist James "J-Dilla" Yancey who made the timeless and genre transcending "Donuts" album before passing away due to health complications caused by Lupus in 2006.
While intended to be an art piece/collectors item, the Dilla is fully functional and shred capable in the hands of fixie gurus.
Constructed of red oak and poplar.
