BOR chainring 2x10 times LK120 | 40 teeth outside
Very lightweight chainring aluminum for mounting on spidering with a bolt circle of 120/80 mm. The bolt circle diameter of 120/80 mm is known from cranks such. Ex. Sram XX, X0 or BOR XX.
The CNC machined chainrings BOR of high-strength aluminum, are hardened as ever in a special process with a glass mount peening and then anodized with 3 times the usual layer thickness. This Double Surface Treatment gives the leaves thereby increased durability!
A combination of BOR 2x chainrings allows a significantly higher grading than by most manufacturers is achieved: 36/24 - 38/25 - 40/26 - 42/27. This is the maximum number of access steps on the big sheet reaches (up to 6) and the wagon is thus DI2 / EPS - compatible.
The chainring has the same thread as the original SRAM XX chainrings (M10x0,75) and is screwed directly.
bolt circle diameter: 120 mm
Compatibility: 10-speed, 11-speed
