Drop-Stop Chainring: for Shimano Road 110 Asymmetric 4-bolt Cranks

Wolf Tooth brings their Drop-Stop chainring profile to the latest generation of Shimano cranks that use the Asymmetric 110bcd 4-bolt chainrings. For optimal chainline Wolf Tooth took care of the math for you, no need for additional spacers as they are already machined into the chainring. The Shimano Asymmetric Drop-Stop chainring mounts to the outside chainring position and is offset inward.  This chainring fits the following cranks:

• Shimano Dura Ace 9000
• Shimano Ultegra 6800
• Shimano 105 5800
• Tiagra 4703 and 4700

Not sure if this chainring will fit your crank, Wolf Tooth has a guide to measuring BCD here.
Wolf Tooth Drop-Stop chainrings will work with 9/10/11 speed drivetrains. If you are looking to use the chainring with a 1x9 setup you must use a 10-speed chain which will work just fine with your 9-speed cassette.

• For Shimano 4-Bolt 110mmBCD Asymmetric cranks
• Mounts in the big ring position
• Use with 10 or 11-speed chains
• 6mm chainring bolts not included
• Made in the USA

Now you can run a 1x chainring on your Shimano quipped cross bike with the Wolf Tooth Drop-Stop chainring.
