We created CAMO (Chainline And Material Optimization) for direct mount style cranksets. Easily swap between chainrings on a whim and enjoy a variable selection of chainring options, all compatible with your selected CAMO spider or BashSpider. With no nuts or spacers involved, swapping chainrings takes less time than brewing a cup of your favorite beverage.

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 SRAM 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.

This is a spider for use with Shimano cranksets that have a removable spider. Key advantages of the CAMO system include:

  • Perfect chainline for wear and shifting precision

  • Optimal material usage for weight, stiffness, and wear

  • Spend less for chainring swapping by buying only the chainring, compared to chainrings that have an integrated spider

  • Swapping chainrings is very fast with only five small bolts and no nuts

  • Availability, as Wolf Tooth has many direct mount options: round or oval, stainless or aluminum, for several cranksets.

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

  • CAMO mounting bolts are included with each spider.


  • 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 Spiders are not compatible with Bash Guide ISCG05


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

  • We recommend the use of a clutch style rear derailleur for the best chain security.

  • If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.

  • 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. Don't worry, 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
