BDop One-By Chainrings


BDop ONE-BY Chainrings fit 5 bolt, 110 BCD cranksets. They can be ordered with or without chainring bolts (which are thinner than chainring bolts for normal 2 chainring set-ups).



BDop ONE-BY Chainrings feature a thick/thin alternating pattern on the teeth to prevent chain drops.

They are 7075AL so they are stiff and long-lasting.

Available in 38T, 40T, and 42T.
