BOR chainring 2x10 times LK104 | 40 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 40er chainring is made specifically for this spider. A matching 26er 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 own 6 switching ramps and integrated -hilfen for a clean and fast gear changes.
The BOR 2x chainrings are DI2 and EPS compatible.
