We have chainrings for SRAM Directmount under Boost (148mm rear hub), with an offset of 3mm. They can also be used with our cranksets, for example, you can now install a shorter shaft on the BB92 Bb.
And as always, the constant spec:
- No need for chain guide
- Материал: алюминий 7075 Т6
- Designed for 10/11/12-speed drivetrain (can be used in 9-speed)
For oval chainring:
- Ovality: 15%
- Mounting angle: 112 degrees (counter-clockwise from the crank)
