Our direct mount chainrings for SRAM cranksets replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet. They are available in 3 different offsets: standard 6mm offset, Boost 3mm offset, and BB30 short spindle/Superboost 0mm offset.
These direct mount chainrings will replace your existing chainring and spider or replace the direct mount ring on SRAM cranksets, including DUB cranks. The ring is attached via 3 bolts on the back side of the spider near the spindle.
This Elliptical chainring is designed for Boost drivelines and is compatible with all chains except Shimano HG12+.


CHOOSE YOUR OFFSET

Standard Road/CX/Gravel: 6mm offset for cyclocross and road crank applications with 47mm chainline
Standard MTB: 6mm offset for non-Boost mountain bikes, GXP and long spindle BB30 cranks for 49mm chainline
Boost: 3mm offset for 52mm chainline
BB30: 0mm offset for BB30 short spindle cranks for 49mm chainline
Fat bikes: If your fat bike has a 170/177 rear hub spacing, use the standard 6mm offset
Praxis Works Road/CX cranks use the 6mm offset. Praxis Works mountain cranks use the 3mm offset for their DM-A and 0mm offset for their DM-B chainrings.


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

POWERTRAC ELLIPTICAL
More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooth’s PowerTrac Elliptical™ (PTE) chainrings. Our proprietary design means a slightly less ovalized ring (10%) with less aggressive timing (112°) than competitors’ versions; any change to your pedal stroke is unnoticeable for most riders, but they still provide the power and traction benefits inherent to oval chainrings.
It’s like having two chainrings in one! With PowerTrac Elliptical rings, the larger-diameter section of the ring engages with the chain at the optimal point on the downstroke, or “Power Zone” – between 1-5 and 7-11 on a clock face – to take advantage of your body’s natural biomechanical power. For example, during this section a PTE 34t ring is equivalent to a 36t round ring. Similarly, in the “Recovery Zone” (11-1 and 5-7) the smaller section on the PTE ring engages, maximizing efficiency in the weakest part of the pedal stroke; here the PTE 34t ring is equivalent to a 32t round ring.
Additionally, the above provides a smoother, more efficient pedal rotation, which means better traction. Steadier torque on the rear wheel means less spinning out in the “Power Zone,” while pedaling is easier during the “Recovery Zone,” so you maintain momentum.
RECOMMENDATIONS

We recommend the use of a clutch style rear derailleur for the best chain security.
We recommend using a T25 L-Wrench or similar for removal and installation of the bolts. 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 we carry replacement bolts
For a longer lasting and more durable option, check out the CAMO System that offers stainless steel chainrings.

Rural Delivery

If your shipping address is classified as a "rural delivery" (RD) address you are required to select the rural delivery shipping option at checkout. Please note that if your address is rural delivery and the incorrect shipping option is selected, your order will not ship until the additional fee for rural delivery has been received. It is the responsibility of the buyer to ensure that the appropriate delivery option is selected to avoid any delays to an order. If you are unsure whether your address is classified as a rural delivery address, please check with your local postal service or contact us for assistance.

 

SHIPPING BIKES:

We do ship bikes! Every bike that is sold is first assembled, tuned, and tested to ensure it is at it's best operational order when it reaches you. If your bike needs to be freighted to you, it will then be boxed with factory-level care and precision to ensure minimal risk and assembly when it arrives.

All bikes that are shipped will be partially disassembled to fit within courier size constraints. We always endeavour to reduce the complexity and amount of re-assembly possible; however, we always recommend you have the bike reassembled or inspected by a qualified bicycle mechanic before riding.

 

DELIVERY FAQ'S

How long does delivery typically take?
Delivery times are generally 3-5 working days on average; however, please allow an extra 1-2 working days for Rural delivery. Note that this is not a guarantee, but an observational quote based on typical delivery times. We often see faster delivery, and rarely see longer wait times unless:

  • You have ordered a bike. Every bike that we sell and ship in a box is first assembled, tuned, and tested to ensure it is it's best operational order when it reaches you. Please allow for an additional 2-3 working days while this takes place. In the case of an e-Bike, please allow for a further working day as we organise Dangerous Goods shippment.
  • Your order is a custom order (not-in-stock or standard stocked items) that has to be specifically ordered from suppliers - we will do our best to communicate any potential delays.
  • If your order requires customisation or additional labour (eg. customising handle bars, changing of parts on a bike, etc.)
  • During peak seasons or public holidays, delivery times can be extended due to courier demand and delay.
  • Please note that there may be delays in receiving your online order from 24th December until the 11th of January, due to limited courier runs.

 

What if there is a delay extending beyond the quoted time?

Please be aware that our control is limited once it has been handed to the courier. Once you get a tracking number, the job is booked with the courier and it is in their hands, not ours, so please be aware of the following:

  • Couriers have their own specified policy regarding time frames, delays, damage and logging inquiries for lost goods.
  • If goods are damaged in transit, the issue needs to be logged directly with the courier company.

Based on this, we always recommend calling the courier company first as sometimes it can be as simple as a lost courier card and the package being at your local depot. All these details will be in the tracking information emailed to you when your order was dispatched.  By directly contacting the people handling your order, it reduces the chain of communication so all your questions can find answers in a faster and more accurate fashion. 

If you are still having trouble or have any additional questions, feel free to contact us and we will do what we can to help.
