Wolf Tooth 5 Bolt Drop Stop Chainring
Description
If you are in need of a 5 Bolt Chainring, chances are Wolf Tooth have an option to suit. Made from a high-grade 7075-T6 aluminium Wolf Tooth's Drop-Stop Chainrings are one of the best performing and longest lasting wide/narrow chainring options on the market.
Drop-Stop technology is Wolf Tooth’s patented wide/narrow chainring design. 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
Compatibility and Specs:
110 BCD:
- These rings are for use with 110 BCD 5 arm cranksets.
- Do NOT fit on the cranksets for Shimano DA 9000 / Ultegra 6800
- Not compatible with Campy CX10/11.
- Can be mounted in either the big or small ring position of a double crankset given chainstay clearance in the small ring position.
- Stock 2x bolts will not work. You will need bolts like our 6mm bolts which are optimized for single ring mounting.
- For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)
- Compatible with all 10-, 11-, and 12-speed chains except Shimano 12-speed chains.
- 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).
- Chainline - varies - these rings can be mounted in either the big or small ring position on double cranksets. The most common mounting is in the big ring position because of chainstay clearance. The ring centerline is ~2mm from the ring's mounting face so they usually sit about 2mm closer to the frame than the stock big ring (depends on the stock ring)
- Weight: 34T - 44g, 36T - 58g, 38t - 66g, 40t - 74g, 42t - 81g, 44t - 90g, 46t - 107g, 48t - 115g, 50t - 125g
110 BCD - Asymmetrical Shimano:
- These rings are for use with 110 BCD 5 arm cranksets.
- Crank arm clocking arrow will be rotated 180 degrees from normal on cranksets that have 4 bolts visible and 1 hidden bolt behind the crank arm (SRAM).
- Do NOT fit on the cranksets for Shimano DA 9000 / Ultegra 6800
- Not compatible with Campy CX10/11.
- Can be mounted in either the big or small ring position of a double crankset given chainstay clearance in the small ring position.
- Stock 2x bolts will not work. You will need bolts like our 6mm bolts which are optimized for single ring mounting.
- For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)
- Compatible with all 10, 11, and 12-speed chains except Shimano 12-speed chains.
- 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).
- Weight: 34T - 44g, 36T - 58g, 38T - 66g, 40T - 74g, 42T - 81g, 44T - 90g, 46T - 107g, 48T - 115g, 50T - 125g
130 BCD:
- These rings are for use with 130 BCD 5 arm cranksets.
- Do NOT fit on the cranksets for Shimano DA 9000 / Ultegra 6800
- Not compatible with Campy CX10/11.
- Sram Exogram cranksets with inset nut must use stock fifth bolt + spacer(s). The Force CX1 bolt features fifth bolt with 1X specific shoulder. This kit can be found online.
- Can be mounted in either the big or small ring position of a double crankset given chainstay clearance in the small ring position.
- 38T important note: The chain may contact the spider arm slightly when using the 38T chainring (see last photo in the product images).
- We recommend filing a small chamfer on the spider arm but you can also just install it and let the chain do the work. This is only an issue with the 38T as the 130 BCD was designed for 39T smallest ring.
- Stock 2x bolts will not work. You will need bolts like our 6mm bolts which are optimized for single ring mounting.
- For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)
- Compatible with all 10-, 11-, and 12-speed chains except Shimano 12-speed chains.

Quality chainring
by Mark
Does exactly what it is supposed to & a breeze to install.
I said goodbye to dropped chains!
by Chris
Premium quality product (made in USA). Does exactly what it's designed for. Not a hint of chain drop after 150km of bumpy commuting. This DropStop is a must if you are riding a 1x drivetrain.
Great replacement for 2x Shimano Tiagra
by Toni
I bought a 42T 110BCD version of this to replace the 2x chainring on Shimano Tiagra 4600. The original chainrings were 32T and 50T. It was really easy to install and surprisingly I was able to use the stock bolts that came with the Tiagra. Granted I've only done couple of rides with the new chainring I'm quite impressed with how smooth it is through the entire range of the rear cassette. Shifting also feels a lot smoother compared to the 2x set-up and the chain seems quite secure over bumps etc. The part was delivered within 3 days of ordering so overall very happy.
Great quality and nice finish.

Great quality and nice finish. The only downside is the price. Surely, the manufacturing of this one only cost few dollars :)
Great chainring for a 1X
by Mark -
Great chainring for a 1X setup, very similar is price and quality to the SRAM 1X chainring however, Wolftooth caters to cranks arms of 130BCD.
Worked great in mud, no
