Direct mount chainrings are mounted on crank without spider. This type of chainring improves stiffness and reduces weight of your drivetrain.
Chainring fits Cannondale Hollowgram and FCA Direct Mount cranksets.
Ai Boost version has smaller offset, that it used on most boost frames (with wider rear axle).
Teeth height and profile are designed for tight fit with chain.
Alternating wide and narrow teeth securely holds the chain and prevents it from falling off.
Special profile of the tooth has a tight contact with the chain that distributes the load and increases the lifespan.
The tooth profile is specially designed for use with chains for mtb.
Wide mud gap and maximized chamfers ejects dirt off and reduces friction.
When riding in very dirty conditions, our technical solutions (profile and tooth height) allow you to be sure that there will be no chain drop or chain suck. Approved by numerous tests.
We recommend using a clutch rear derailleur for holding chain better on the chainring.
Use a new chain with a new chainring.
Chainrings are made of 7075-T6 aluminum alloy, using modern CNC milling machines.
Surface is anodized.
For Cannondale and FCA cranksets.
The chainrings can be used with the following drivetrains: 1×10, 1×11 and 1×12
