SHIMANO ROAD 1X OVAL DROP-STOP B CHAINRING - 110 x 4 BCD
SHIMANO ROAD 1X OVAL DROP-STOP B CHAINRING - 110 x 4 BCD
Low stock
Wolf Tooth was first to market with cyclocross 1x specific chainrings because we saw cyclocross as the perfect use for our patent pending Drop-Stop® technology. These beautifully machined 110 BCD asymmetric 4-bolt chainrings are optimized for your 1x Shimano CX / road / gravel drivetrain, whether you run Dura Ace 9000, Ultegra 6800, 105 5800, or Tiagra 4700. They are also offset for the ideal 1x chainline.
Fits 110 BCD Asymmetric 4-bolt Shimano cranks.
Drop-Stop technology: On Wolf Tooth’s patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.
Alternating wide/narrow tooth pattern prevents chain derailment.
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.
COMPATIBILITY
Fits Shimano 110 BCD asymmetric 4-bolt cranks
All sizes are compatible with Dura Ace 9000, Ultegra 6800, 105 5800, RS510, Tiagra 4700 or 4703, Sora R3000 or R3030, and Claris R2000 or R2030 cranks.
38-50t are compatible with 105 R7000, Ultegra R8000, and Dura-Ace R9100.
NOT compatible with Dura-Ace R9200 and Ultegra R8100
Size 42t and larger will work with the Dura Ace 9100 power meter
Mounts in the big ring position of the cranks but is offset inward for perfect chainline.
The stock 2x bolts will not work. You will need our 6mm bolts, which are optimized for single ring mounting.
If using a 9-speed drivetrain use a 10-speed chain. It fits tighter for better chain retention
Chainline 47.5mm
Use Drop-Stop B for all 9, 10, and 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo, SRAM Eagle, SRAM Road and Transmission (T-type) Flattop chains
DROP-STOP TECHNOLOGY
Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability.
RECOMMENDATIONS
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.
We recommend the use of a clutch style rear derailleur for the best chain security.

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.
