BOR chainring 2x10 times LK104 | 36 teeth outside
BOR and Tune have a 2-fold Spider developed corresponding to the fastening principle of Sram XX and Co. with 120/80 bolt pattern, but one size smaller. The Spider with 104 / 64er bolt pattern allows to mount smaller chainrings, making just on a 29er sense. The chainring bolts are thereby directly screwed into a thread in the large chainring. The small chainring is mounted conventionally on threads in Spider. The 36er chainring is made specifically for this spider. A matching 22er or 24er chainring is available in our shop. For increased mileage, the chainrings are blasted with glass beads, which hardens the surface and compacted.
The chainrings of BOR have 4 switching ramps and integrated -hilfen for a clean and fast gear changes.
The BOR 2x chainrings are DI2 and EPS compatible.
bolt circle diameter: 104 mm
