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

This is a spider for use with the Cannondale cranksets that have a removable spider.

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

  1. Perfect chainline for wear and shifting precision

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

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

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

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

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




  • This is a spider for use with the Cannondale cranksets that have a removable spider
  • 3 different chainline options are available.  The number and letter refer to the mm offset and direction from the mounting face to the centerline of the teeth:
    • M9 (minus 9mm - standard dish towards the frame)
      • For use on standard (non-Ai offset) mountain bikes
    • M4 (minus 4mm - Ai offset)
      • For use on Cannondale bikes with the Ai (asymmetric integration) offset rear triangle AND all Cannondale 27.5 Plus bikes
      • For use on 2x Fat CAAD (a 166mm spindle)
    • M1 (minus 1mm - dished towards the frame)
    • M1 (minus 1mm - dished towards the frame)
      • Cannondale cyclocross and road bikes (38T max CAMO chainring)
      • Ai cyclocross bikes with 155mm spindle (38T max CAMO chainring) 
  • FSA direct mount cranksets using boost chainline are compatible with Camo M9 (minus 9mm) offset spider when using the Wolf Tooth 2.5mm FSA spacer available separately.
  • CAMO mounting bolts can be purchased separately, but all the CAMO spiders come with stainless steel bolts if you don't order them.
  • All Camo Spiders are not compatible with Bash Guide ISCG05

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.  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 threadlock
