Wolf Tooth 104 BCD Stainless Steel Chainrings

Possibly the toughest chainrings available which last up to 10x longer than aluminium!!!

416 stainless steel is not the first material choice for most component manufacturers looking to use stainless steel (most use soft 300 series). That is because 416 is hard...hard because the raw billet is expensive, hard because it takes a long time to machine. However, that did not stop Wolf Tooth because there is no denying that it is the best material for those that need the ultimate durability in a chainring. These stainless steel chainrings are not only beautiful, but they will last 5-10 times longer than their aluminium versions.


Compatibility:
  • These are functionally the same as the aluminium 104 BCD rings.
  • These rings fit any 104 BCD crankset, and here are instructions on how to measure your BCD
  • Notes for those the plan to run a 32t chainring on a 2x Shimano crankset (XT, SLX, or Deore).
  • 30t x 104 ring is the only Quarq power meter compatible 30t ring available!
  • For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)
  • Compatible with all 10, 11, and 12 speed chains (Including SRAM Eagle)
  • If using a 9 speed drivetrain use a 10 speed chain (shifts and works well on a 9 speed drivetrain and fits the ring tighter for better chain retention).
  • Provide a great chainline on most boost bikes. See this explanation for details.
  • QUARQ is a trademark of SRAM, LLC, registered in the U.S. and other countries. 



Tech Specs:
  • Design and manufactured in Minneapolis, MN USA
  • Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability
  • Recommend the use of a clutch style rear derailleur for the best chain security.
  • Made from hardened and electropolished 416 stainless steel
  • Will last 5-10x longer (or even more) than our 7075 Aluminum chainrings
  • Colors - raw SST
  • Chainline (approximate as BB centring and cranksets vary)
  • 30t - 48mm on 3x cranksets and 49mm on 2x
  • 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.
  • Weight - 30t - 72g, 32t - 88g



About the Wolf Tooth Drop-Stop design:

Wolf Tooth Components are the best performing and longest lasting wide/narrow chainrings on the market, and that is no accident. We've put countless hours into designing, prototyping, and testing to come up with our innovative new tooth profile, which is pending multiple patents. Test riders all over the world have confirmed that this design provides unparalleled performance. Here are the details of WHY it works:   

Asymmetric tooth shape:   


 
This is a close up view of our new tooth profile. Notice that right side of the tooth has a very different shape than the left side. The right side of the tooth transmits force to the chain and the left side provides clearance for mud and debris. Since they have completely different functions it makes sense that they are designed differently. Extra strength where you need it, less material where you don't:

 

This picture shows a top and side view of our chainring with a chain so you can see how they fit together. Notice that the right side of the tooth is as wide as we can make it to maximise amount of area in contact. More area in contact means the load is spread over a larger area which in turn minimises wear on the tooth. The left side of the tooth helps to guide the chain as it meshes with the chainring but it does not have to transmit any load. The left side of the tooth is narrower than the roller pin on the chain. Wear is not a concern on this side of the tooth so we removed extra material to create a channel for mud to flow away. More clearance means less friction and less chance of mud causing a dropped chain.  
 


This cross section shows the mud purging channel that allows Drop-Stop chainrings to rip through mud without dropping the chain. Notice how the extra relief on the left side of the tooth provides room for mud to flow. Mud relief cutouts on the valleys between the teeth provides space for mud to flow between the chain plates and chain roller. All surfaces are angled so there are no sharp corners for mud and grease to build up.
