Wolf Tooth CAMO RaceFace CINCH Reverse Dish Spider - P2 for 58mm Chainline/+4mm Offset
CAMO Stands for Chainline and Material Optimization. Available in various chainlines and spider configurations, CAMO spiders allow the use of previously unavailable chainring styles, materials and chainline in a lightweight, modular and customizable package. These spiders are only compatible with CAMO rings and bolts.
I used this to correct the chainline of my 2019 trek farley. I upgraded it to gx eagle 1x12 at the same time converted the 192mm crank spindle to 170mm to narrow the qfactor for more pedaling effeciency. This spider gave me the perfect chainline!
