This is a CAMO BashSpider ONLY. A CAMO Chainring is required to complete this system.

The CAMO BashSpider is the world's only crankset-mounted boost bash ring. This is a spider with an integrated bash ring for use with direct mount Shimano cranksets. The CAMO BashSpider pairs with a CAMO chainring to complete the CAMO System. 

The "rolling" ability of the BashSpider allows the rider to move easily over obstacles. Bash rings that are mounted on the crankset are better supported than bash rings that are mounted to the frame or bottom bracket, as bash solutions like ISCG 05 can void frame warranties. 

The CAMO chainring system was created by the Wolf Tooth engineers for Chainline And Material Optimization on direct mount style chainrings. Key advantages include:

  1. Perfect chainline: wear and shifting precision

  2. Optimal material usage: weight, stiffness, and wear

  3. Price: less expensive replacement chainrings

  4. Swapping simplicity: quick chainring change with five small bolts and no nuts

  5. Availability: Wolf Tooth has everything for your direct mount needs—round or oval, stainless or aluminum, no matter the crankset

  6. Flash: spider colors and bolt colors add a little more style to your  ride

  7. Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud-shedding ability




  • This spider is designed to work with Shimano cranksets that have a removable spider.
  • Not compatible with the XTR 9100-1, XTR 9100-2, or XTR 9130 crankset (narrow q-factor version)
  • Currently available only for Boost chainline. The number and letter refer to the mm offset and direction from the mounting face to the centerline of the teeth:
      • M5 (minus 5mm - Boost)
        • dished towards the frame
      • CAMO mounting bolts are included with each spider but can also be purchased separately in a variety of colors
      • Only works with CAMO 28T-34T round or 30T-32T elliptical chainrings

      Installation notes:

      • You will be able to access all bolts without removing the spider
      • Line up the little dot on the ring with the dot on the spider. You cannot install the ring in the wrong rotational orientation.
      • Be sure the bosses on the spider "plug in" to the chainring.
      • Torque bolts only to 4-5 Nm and use blue Loctite threadlocker
