Tune BOR and have developed a 2-fold Spider corresponding to the fastening principle of SRAM XX and Co. with 120/80 bolt circle diameter corresponding to small, however, a number. The Spider with 104 / 64er bolt circle diameter allows to mount smaller chainrings, making just on a 29er sense. Chainring bolts are thereby directly screwed into a thread in the large chainring. The small chain wheel is mounted on conventional thread in the spider. The 38er chainring is made specifically for this spider. A suitable 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 quick gear changes.
This 2x10 Spider with 104/64 can also be found on the THM M3.
