BDop One-By Kit: Road Disc


The BDop ONE-BY kit is for 5-Bolt, 110 BCD cranks.

It includes the BDop R142-11 which is a 6-Bolt, road disc specific hub, a one-by chainring, and the chainring bolts needed to convert double cranksets to one-by.



The One- by Chainrings:
BDop ONE-BY Chainrings are for 5 bolt, 110 BCD cranksets.
They feature a thick/thin alternating pattern on the teeth to prevent chain drops.
Machined from 7075AL they are stiff and long-lasting.
Available in 38T, 40T, and 42T.

The One- by Chainring Bolts:
 Machined from 7075AL, the One-by chainring bolts are strong and durable.
They are for single chainrings which means they are narrower than bolts for double chainrings.

The BDop R142-11 Hub:
The BDop R142-11 hubs were one of the first hubs specifically for road disc bikes. They use a road specific chain line (not MTB chain line) which gives a better chain line than repurposed MTB hubs.
See the video below for more details.
The hub is available in:
Drillings: 24H, 28H
Freehub: Shimano 10/11 w ABG, Sram XD-R
Thru Axle: QR, 10mm*135mm, 12mm*135mm, 12mm*142mm
