Tune and BOR have a 2-fold Spider developed of the fastening principle of Sram XX and Co. with 120/80 bolt circle diameter corresponds to, but one size smaller. The Spider with 104 / 64er bolt circle diameter allows to mount smaller chainrings, making just on a 29er sense. The chainring bolts
be it directly screwed into a thread in the large chainring. The small chainring is mounted conventionally on threads in Spider. The 38er 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 Tune have 4 switching ramps and integrated -hilfen for a clean and fast gear changes.
This 2x10 Spider with 104/64 can also be found at the THM Clavicula M3.
