Discover the best bike components at Escapa. TheBpart Oval Chainring for Race Face 12V SH 6DM Cranksets iscompatible with RACE FACE RF Next SL, RF SIXC, RF Turbine, RF Atlas, and AEFFECT Cinch cranksets. Our chainrings are 100% CNC-machined from a solid block of 7075 T6 aluminum to ensure extreme strength and excellent durability, thanks to the anodized finish across our entire color range. They feature a unique tooth profile and a narrow-wide design to prevent chain drop. Perfect for 1×12 drivetrains. Direct mount on Race Face cranksets.
Narrow/Wide Design
While riding, the movement and vibration of the chain cause it to shift from side to side, making it easy for the chain to come off. Bpart Components’ narrow/wide chainrings limit this lateral movement and reduce the chance of the chain coming off on your most extreme rides.
Tooth Profile
The precise tooth profile design on Bpart chainrings ensures maximum chain contact with the chainring under all riding conditions, delivering unmatched smoothness and precision in chain movement.
Tooth Height
When we combine a well-designed profile with a carefully selected tooth height, we get a winning combination:
Looking at the graph, we can clearly see the mechanical difference between a low profile (A) and a high profile (B); the chain will come off more easily on a drivetrain with “low” teeth than with “high” teeth, which are found on Bpart chainrings.
Mud Clearance
We observed in a narrow-wide design that the tighter the chain fits against the chainring, the better the drivetrain performance; however, there is a trade-off when riding in muddy conditions: the space between the chain and the chainring is very small, which promotes mud buildup since it cannot be easily removed. As a result, the chain may come off if it does not seat properly.
At Bpart, we’ve focused on maximizing the space between the chain and the mud-shedding bevel, eliminating unnecessary recesses that encouraged the buildup of dust and mud.

The variable thickness of our teeth (wide-narrow) prevents potential chain drops
Our specially shaped tooth profile ensures greater contact with the chain and a smoother pedaling experience
By increasing the tooth height, we improve chain retention even when there is jerking or rattling.
The vents on the back of the tooth prevent mud buildup and unnecessary wear.
We reduce the bike’s weight by 150 to 350 gr by eliminating the front derailleur.
A chain guide isn’t necessary unless you’re a very aggressive rider; in that case, check out our Trail Up chain guide.
