Wolf Tooth Direct Mount Stainless Steel for SRAM Cranks
Possibly the toughest chainrings available which last up to 10x longer than aluminium!!!
It is exciting to be a part of the recent Enduro, All Mountain and Trail fueled trend that is shifting mountain bike and component design focus from "weight weenie" to "fun, functional, and DURABLE". Made from 416 stainless steel and heat-treated for hardness and strength, these chainrings are not only beautifully machined but they will stand up to whatever you can dish out. These chainrings are functionally the same as our Direct Mount for SRAM
rings (dished roughly 6mm) except they are made of stainless steel for increased durability. They will have the perfect perfect 1x chainline on SRAM GXP cranks, BB30 Long Spindle cranks, SRAM Road cranks, and SRAM CX1 cranks with removable spiders.
- These are 6mm offset direct mount chainrings to fit SRAM cranks
- These direct mount chainrings will replace your existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle. You will use these same 3 bolts to attach the Wolf Tooth SDM (TM) chainring.
- Provide a great chainline on most boost bikes. See this explanation for details.
- They fit on SRAM cranksets with removable spiders that are either GXP, Long Spindle BB30 or any Road/CX crankset
- Models include but are not limited to: S2200, S2210, X9, X0, X01, XX1, X1 1400, SRAM Road/CX, Truvativ AKA Cranksets (GXP version), and newer S1400 (or X7) .
- If you are planning to use this on an X9 or XX1 fat bike crankest, check out this explanation of chainline and hub spacing.
- This decision tree will help you determine if you have a removable spider, and if you do what ring you need for your cranksets (there are 2 different ring offsets used by the BB30/PF30 cranksets):
- 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).
- Direct Mount bash rings are specially designed to mount to these stainless rings.
- We recommend using a T25 L-Wrench like this one or similar for removal and installation of the bolts.
- The stock bolts are easily damaged when removing them to install a direct mount chainring. We have replacement bolts if you need them.
- Design and manufactured in the Minneapolis, MN USA
- Wolf Tooth’s patent pending 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.
- Mateial - hardened and electropolished 416 stainless steel.
- Wolf Tooth Components stainless steel rings will last 5x or more longer than Aluminum rings.
- Colors - silver
- Chainline - 49mm when used on mountain bike cranksets and 44-45mm when used on CX/Road cranksets
- 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.
- A T25 Torx wrench is required to remove the bolts that secure the the chainring or spider to the crankarm.
- An L-wrench works best since the crank spindle may contact a socket adapter and prevent it from engaging properly.
- Use the same 3 bolts to attach the Wolf Tooth ring or if you need, we carry replacement bolts
- Weight - 24T= 106g, 26T= 123g, 28T= 137g, 30T=155g
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.
