Precision machined in Minnesota from premium 7075-T6 aluminum, this chainring delivers optimized chain retention, ideal chainline, and long-term durability for modern 1x performance builds.\u003c\/p\u003e\n\n\u003cp\u003eDesigned specifically for Shimano’s 110 BCD asymmetric 4-bolt crank standard, this chainring mounts in the big ring position and is offset inward to achieve a \u003cstrong\u003e47.5mm chainline\u003c\/strong\u003e—ideal for 1x drivetrains. The result is improved drivetrain alignment, reduced cross-chaining, and smoother overall performance whether you're racing cyclocross or building a streamlined gravel machine.\u003c\/p\u003e\n\n\u003cp\u003eAt the core is Wolf Tooth’s patented \u003cstrong\u003eDrop-Stop® wide\/narrow tooth profile\u003c\/strong\u003e. The wide teeth provide maximum chain contact on the drive side to distribute load and increase wear life, while the narrow teeth allow mud and debris clearance. The alternating tooth pattern actively reduces chain derailment—especially important in rough or muddy conditions.\u003c\/p\u003e\n\n\u003ch3\u003e110 BCD Asymmetric 4-Bolt Chainring Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBCD:\u003c\/strong\u003e 110mm Asymmetric 4-Bolt (Shimano standard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Position:\u003c\/strong\u003e Big ring position (offset inward for 1x)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainline:\u003c\/strong\u003e 47.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Profile:\u003c\/strong\u003e Drop-Stop® wide\/narrow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075-T6 aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeights:\u003c\/strong\u003e 38T – 66g | 40T – 74g | 42T – 81g | 44T – 90g\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Made in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCranks:\u003c\/strong\u003e Shimano 110 BCD Asymmetric 4-bolt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Models:\u003c\/strong\u003e Dura-Ace 9000, Ultegra 6800, 105 5800, RS510, Tiagra 4700\/4703, Sora R3000\/R3030, Claris R2000\/R2030\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e38T–50T:\u003c\/strong\u003e Compatible with 105 R7000, Ultegra R8000, Dura-Ace R9100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e36T:\u003c\/strong\u003e Not compatible with R7000, R8000, R9100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNot Compatible:\u003c\/strong\u003e Dura-Ace R9200, Ultegra R8100, 105 R7100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Meter:\u003c\/strong\u003e 42T and larger compatible with Dura-Ace R9100 power meter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolts Required:\u003c\/strong\u003e 6mm single-ring chainring bolts (stock 2x bolts will not work)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDrivetrain Notes\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eFor 9-speed drivetrains, use a 10-speed chain for tighter fit and improved retention.\u003c\/li\u003e\n  \u003cli\u003eClutch-style rear derailleur recommended for optimal chain security.\u003c\/li\u003e\n  \u003cli\u003eFor extremely muddy conditions, consider adding a chainguide or chainkeeper.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benifits\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptimized 1x Chainline:\u003c\/strong\u003e Inboard offset improves drivetrain alignment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnhanced Chain Retention:\u003c\/strong\u003e Drop-Stop® tooth shaping reduces derailment risk.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLightweight Strength:\u003c\/strong\u003e 7075-T6 aluminum balances durability and minimal weight.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision Fit:\u003c\/strong\u003e Engineered specifically for Shimano’s asymmetric 110 BCD pattern.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThe Wolf Tooth 110 BCD Asymmetric 4-Bolt Chainrings for Shimano Cranks remain a proven solution for riders moving to a 1x drivetrain on compatible Shimano road and gravel cranks.
